  • How do you apply a Theme to a Silverlight 3 application?

    - by skb
    I am trying to build a Silverlight website, using standard Silverlight controls. I read that Silverlight 3 comes with 9 proffessionally design Themes. I really want to use them, but everywhere I look just talks about making you own theme, or other tangential topics. Can anyone tell me how to apply one of the out-of-the-box themes? Or, if there is any tribal knowledge that those themes suck, where some other standard themes can be found?

    - by Alex
    Ok, I have a Preferences activity set with an XML layout. Here I have a couple of Preferences that open some dialogs. On these preferences I want to have an arrow on the right of them like in the screenshot. How I do this, is something related to the theme ? First screenshot is how I want to look, second is what I have now. http://img545.imageshack.us/i/screenshot1zlk.png/ http://img405.imageshack.us/i/tsc3.png/

  • Can I import another users calendar into Outlook 2010 and maintain his color highlights?

    - by Matthias Mayer
    I am importing a colleagues complete Outlook 2010 calendar (sent by mail as .ics file). However, all coloring is lost: categories, automatically formatted entries, etc. are not visualized in my colleagues colors - just in a non-distinguishable standard office style. Is there a way that my colleague also sends me his color preferences, ie. to maintain his individual coloring in my view? Thanks in advance! Matthias

  • How can I add color highlighting for PHP functions?

    - by Jeff Gortmaker
    I've recently begun using Notepad++, and have found a part of its styling functionality that confuses me. I'm currently attempting to color all of PHP's defined functions (such as count(), strlen(), etc.). In the Settings-Style Configurator, you cannot add a new style for such a function list. Instead, I have begun editing the stylers.xml and langs.xml. To add the new coloring, in langs.xml, I've modified the php section to the following: <Language name="php" ext="php php3 phtml" commentLine="//" commentStart="/*" commentEnd="*/"> <Keywords name="instre1">[default keywords]</Keywords> <Keywords name="instre2">[my function list]</Keywords> </Language> The [default keywords] and [my function list] are replaced with wordlists. I've also edited the php section in stylers.xml to look like the following: <LexerType name="php" desc="php" ext=""> <WordsStyle name="QUESTION MARK" styleID="18" fgColor="FF0000" bgColor="FDF8E3" fontName="" fontStyle="0" fontSize="" /> <WordsStyle name="DEFAULT" styleID="118" fgColor="000000" bgColor="FEFCF5" fontName="" fontStyle="0" fontSize="" /> <WordsStyle name="STRING" styleID="119" fgColor="FF0000" bgColor="FEFCF5" fontName="" fontStyle="0" fontSize="" /> <WordsStyle name="STRING VARIABLE" styleID="126" fgColor="FF0000" bgColor="FEFCF5" fontName="" fontStyle="1" fontSize="" /> <WordsStyle name="SIMPLESTRING" styleID="120" fgColor="FF0000" bgColor="FEFCF5" fontName="" fontStyle="0" fontSize="" /> <WordsStyle name="WORD" styleID="121" fgColor="008040" bgColor="FEFCF5" fontName="" fontStyle="1" fontSize="" keywordClass="instre1">True False</WordsStyle> <WordsStyle name="NUMBER" styleID="122" fgColor="FF0000" bgColor="FEFCF5" fontName="" fontStyle="0" fontSize="" /> <WordsStyle name="VARIABLE" styleID="123" fgColor="0080FF" bgColor="FEFCF5" fontName="" fontStyle="0" fontSize="" /> <WordsStyle name="COMMENT" styleID="124" fgColor="FF8040" bgColor="FEFCF5" fontName="" fontStyle="0" fontSize="" /> <WordsStyle name="COMMENTLINE" styleID="125" fgColor="FF8040" bgColor="FEFCF5" fontName="" fontStyle="0" fontSize="" /> <WordsStyle name="OPERATOR" styleID="127" fgColor="8000FF" bgColor="FEFCF5" fontName="" fontStyle="0" fontSize="" /> <WordsStyle name="FUNCTIONS" styleID="128" fgColor="000080" bgColor="FEFCF5" fontName="" fontStyle="1" fontSize="" keywordClass="instre2"></WordsStyle> </LexerType> The changed part is the last "FUNCTIONS" line. When I restart Notepad++ and go into the Settings-Style Configurator section, under the php language, the FUNCTIONS style exists. I can change the style's color, and can see the entire keyword list under 'Default Keywords'. However, it is not changing the coloring of the words in my code. When I edit the WORD style, which contains stuff like 'if', 'and', and 'true', things change accordingly in my code. Any ideas on how to make this work?

  • asp.net, how to change text color to red in child nodes in VB codes?

    - by StudentIT
    I got everything worked now by list of server Name but I want to add a IF statement by checking a column from SQL Server called Compliance by either True or False value listed. If it False, the Name will change text color to Red. If it True, the Name won't change text color. I am not sure how add that in VB codes side. I am pretty sure that I would need to put IF statement inside While dr.Read(). I am pretty new to VB.Net and not sure which VB code that change text color. Here is my VB codes, Sub loadData() 'clear treeview control TreeViewGroups.Nodes.Clear() 'fetch owner data and save to in memory table Dim sqlConn As New System.Data.SqlClient.SqlConnection((ConfigurationManager.ConnectionStrings("SOCT").ConnectionString)) Dim strSqlSecondary As String = "SELECT [Name] FROM [dbo].[ServerOwners] where SecondaryOwner like @uid order by [name]" 'Getting a list of True or False from Compliance column Dim strSqlCompliance As String = "SELECT [Compliance] FROM [dbo].[ServerOwners] where SecondaryOwner like @uid order by [name]" Dim cmdSecondary As New System.Data.SqlClient.SqlCommand(strSqlSecondary, sqlConn) Dim cmdCompliance As New System.Data.SqlClient.SqlCommand(strSqlCompliance, sqlConn) cmdSecondary.Parameters.AddWithValue("@uid", TNN.NEAt.GetUserID()) cmdCompliance.Parameters.AddWithValue("@uid", TNN.NEAt.GetUserID()) Dim dr As System.Data.SqlClient.SqlDataReader Try sqlConn.Open() Dim root As TreeNode Dim rootNode As TreeNode Dim firstNode As Integer = 0 'Load Primary Owner Node 'Create RootTreeNode dr = cmdSecondary.ExecuteReader() If dr.HasRows Then 'Load Secondary Owner Node 'Create RootTreeNode root = New TreeNode("Secondary Owner", "Secondary Owner") TreeViewGroups.Nodes.Add(root) root.SelectAction = TreeNodeSelectAction.None rootNode = TreeViewGroups.Nodes(firstNode) 'populate the child nodes While dr.Read() Dim child As TreeNode = New TreeNode(dr("Name"), dr("Name")) rootNode.ChildNodes.Add(child) child.SelectAction = TreeNodeSelectAction.None End While dr.Close() cmdSecondary.Dispose() End If 'check if treeview has nodes If TreeViewGroups.Nodes.Count = 0 Then noServers() End If Catch ex As Exception hide() PanelError.Visible = True LabelError.Text = ex.ToString() Finally sqlConn.Dispose() End Try End Sub

  • How do I determine if a terminal is color-capable?

    - by asjo
    I would like to change a program to automatically detect whether a terminal is color-capable or not, so when I run said program from within a non-color capable terminal (say M-x shell in (X)Emacs), color is automatically turned off. I don't want to hardcode the program to detect TERM={emacs,dumb}. I am thinking that termcap/terminfo should be able to help with this, but so far I've only managed to cobble together this (n)curses-using snippet of code, which fails badly when it can't find the terminal: #include <stdlib.h> #include <curses.h> int main(void) { int colors=0; initscr(); start_color(); colors=has_colors() ? 1 : 0; endwin(); printf(colors ? "YES\n" : "NO\n"); exit(0); } I.e. I get this: $ gcc -Wall -lncurses -o hep hep.c $ echo $TERM xterm $ ./hep YES $ export TERM=dumb $ ./hep NO $ export TERM=emacs $ ./hep Error opening terminal: emacs. $ which is... suboptimal.

  • how can i have a working dropdownlist with links from a csv in php

    - by Mark Dekker
    I have a website that loads a CSV, divides it into parts, and shows these parts. There are 7 parts, and since it is for a music store it is sliced like this: the name of the product the subname the price the stock in one shop the stock of the other shop the group name the brandname What i have now is that it shows 12 products on 1 page, with a next and previous link on top of the page. The pages are made with the group name, every group has it's own page, so you have a drums page, guitar page, speaker page. That all works great. What i programmed in there is a dropdownlist, it drops down a list of brandnames, which should narrow the search for a person who is looking at the products. Problem is right now, that the dropdown menu works, i see the brands, but they are NONE clickable, only the brands that are currently on the page are shown, so NOT all the brands from that group are shown, only the 12 that are currently showing, when you press next, it shows 12 more brands, but i want them to be shown right on the start. And the third problem is, when it is showing the brands, it shows them double or triple, depending on how many products have the same brand. Is there a way what i want, with this code as a basis ? <html> <body bgcolor=#E2E965 link=black vlink=black alink=black text=#D5DF23> <style type="text/css"> #nav, #nav ul { padding: 0; margin: 0; list-style: none; } #nav li { float: left; width: 120px; } #nav ul { position: absolute; width: 120px; left: -1000px; } #nav li:hover ul { left: auto; } <!-- a {text-decoration:none} //--> body { scrollbar-arrow-color: #E2E965; scrollbar-face-color: #D7182A; scrollbar-highlight-color: #000000; scrollbar-3dlight-color: #D6DF23; scrollbar-shadow-color: #00000; scrollbar-darkshadow-color: #00000; scrollbar-track-color: #D6DF23; } input:link {text-decoration: none; color: #E2E965;} input:visited {text-decoration: none; color: #E2E965;} input:active {text-decoration: none; color: #E2E965;} .spacer_black { margin: 0px; padding: 0px; border: 5px; height: 2px; width: 100%; line-height: 0px; font-size: 0px; background-color: #000000;} </style> <table width=800 border=0><td> </html> <?PHP $offset = isset($_GET['offset'])?$_GET['offset']:0; $LinesToDisplay = 12; $row = $offset + $LinesToDisplay; $row2 = $offset - $LinesToDisplay; $file_handle = fopen("web.txt", "rb"); error_reporting( E_ALL ); // DEBUGGING $SelectArray=array(); while ((($parts = fgetcsv($file_handle,4096,"|")) !== FALSE) && ($LinesToDisplay > 0) && (!feof($file_handle))) { //new code //skip first $offset lines $num = count($parts[6]); $SelectArray[]=$parts[6]; if ($parts[5] == 9999) { if ($offset-- > 0) {continue;} $parts[0] = ucwords(strtolower($parts[0])); $parts[1] = ucwords(strtolower($parts[1])); ?> <td> <?php echo "<table BACKGROUND='background.jpg' border=0 width=250><td width='243' height='105'>"; echo "<font size=-1 face='helvetica' color=#812990><b>$parts[0]</b></font>"; echo "<i>"; ?> <html> <div onMouseOver="this.style.color = 'black';" onMouseOut="this.style.color = '#D5DF23';"> </html><?php echo "<font size=2>-$parts[1]</font>"; echo "</div></i>"; ?><html><a href="#" title="Koop nu de <?php echo $parts[0]; ?>" onClick="window.open('form.php?p=<?php echo urlencode($parts[0]); ?>','popuppage','width=400,height=400,top=250,left=250,resizable=0,statusbar=0,titlebar=yes,toolbar=no,scrollbars=no,location=no,directories=no');"> <div><img src='ster.jpg' border=0 width='46' align='right'></a> <a href="#"><img src='envelope.jpg' border=0 width='46' align='right'title="Heeft u een vraag over <?php echo $parts[0]; ?>" onClick="window.open('vraag.php?p=<?php echo urlencode($parts[0]); ?>','popuppage','width=400,height=400,top=250,left=250,resizable=0,statusbar=0,titlebar=yes,toolbar=no,scrollbars=no,location=no,directories=no');"> <div></a> <TABLE BORDER='0' cellpadding='0' CELLSPACING='0'> <TR> <TD WIDTH='70' HEIGHT='20' BACKGROUND='pricebackground.jpg' VALIGN='bottom'> <center> <font size=2 color=white face='helvetica'> <b></html> <?php echo "€ $parts[2]"; ?> </b> </td> </tr> </table> <?php echo "<b><font size=3 color=#D7182A>Op Voorraad In:<br></font>"; echo ("<font color=black> Amsterdam </font>"); if ( $parts[3] >= 1 ) echo ("<IMG SRC =green.gif>").""; if ( $parts[3] <= 0 ) echo ("<IMG SRC =red.gif>").""; echo ("<font color=black> Utrecht </font>"); if ( $parts[4] >= 1 ) echo ("<IMG SRC =green.gif>")."</td></table></b><p style='margin:9px;'>"; if ( $parts[4] <= 0 ) echo ("<IMG SRC =red.gif>")."</td></table></b><p style='margin:9px;'>"; $LinesToDisplay--; if ($LinesToDisplay/3==intval($LinesToDisplay/3)) { echo "<tr><td>"; } }} fclose($file_handle); ?> <tr align=right> <select style="background-color: #FFFFFF; color: #000000; font-family: Arial; font-weight: none; font-size: 12; width: 150px; "> <?php $i=1; foreach ($SelectArray as $val){ echo "<option value=\"$i\">$val</option>\n"; $i++; } ?> </select> <font color=black><body alink=black vlink=black link=black text=black> <center><a href="occasiona.php?offset=<?php echo $row2; ?>" align=center>&laquo; previous</a> || <a href="occasiona.php?offset=<?php echo $row; ?>">next &raquo;</a></table></html>

  • how to set a fixed color bar for pcolor in python matplotlib?

    - by user248237
    I am using pcolor with a custom color map to plot a matrix of values. I set my color map so that low values are white and high values are red, as shown below. All of my matrices have values between 0 and 20 (inclusive) and I'd like 20 to always be pure red and 0 to always be pure white, even if the matrix has values that don't span the entire range. For example, if my matrix only has values between 2 and 7, I don't want it to plot 2 as white and 7 as red, but rather color it as if the range is still 0 to 20. How can I do this? I tried using the "ticks=" option of colorbar but it did not work. Here is my current code (assume "my_matrix" contains the values to be plotted): cdict = {'red': ((0.0, 1.0, 1.0), (0.5, 1.0, 1.0), (1.0, 1.0, 1.0)), 'green': ((0.0, 1.0, 1.0), (0.5, 1.0, 1.0), (1.0, 0.0, 0.0)), 'blue': ((0.0, 1.0, 1.0), (0.5, 1.0, 1.0), (1.0, 0.0, 0.0))} my_cmap = matplotlib.colors.LinearSegmentedColormap('my_colormap', cdict, 256) colored_matrix = plt.pcolor(my_matrix, cmap=my_cmap) plt.colorbar(colored_matrix, ticks=[0, 5, 10, 15, 20]) any idea how I can fix this to get the right result? thanks very much.

CAML it’s a markup language like html that allows developers to do queries against SharePoint lists, it’s syntax is very easy to understand and it allows to add logical conditions like Where, Contains, And, Or, etc, just like a SQL Query. For one of our projects we have the need to do a filter on SharePoint views, the problem here is that the view it’s a list containing a CAML Query with the filters the view may have, so in order to filter the view that’s already been filtered before, we need to append our filters to the existing CAML Query. That’s not a trivial task because the where statement in a CAML Query it’s like this: <Where>   <And>     <Filter1 />     <Filter2 />   </And> </Where> If we want to add a new logical operator, like an OR it’s not just as simple as to append the OR expression like the following example: <Where>   <And>     <Filter1 />     <Filter2 />   </And>   <Or>     <Filter3 />   </Or> </Where> But instead the correct query would be: <Where>   <Or>     <And>       <Filter1 />       <Filter2 />     </And>     <Filter3 />   </Or> </Where> Notice that the <Filter# /> tags are for explanation purpose only. In order to solve this problem we created a simple component, it has a method that receives the current query (could be an empty query also) and appends the expression you want to that query. Example: string currentQuery = @“ <Where>    <And>     <Contains><FieldRef Name='Title' /><Value Type='Text'>A</Value></Contains>     <Contains><FieldRef Name='Title' /><Value Type='Text'>B</Value></Contains>   </And> </Where>”; currentQuery = CAMLQueryBuilder.AppendQuery(     currentQuery,     “<Contains><FieldRef Name='Title' /><Value Type='Text'>C</Value></Contains>”,     CAMLQueryBuilder.Operators.Or); The fist parameter this function receives it’s the actual query, the second it’s the filter you want to add, and the third it’s the logical operator, so basically in this query we want all the items that the title contains: the character A and B or the ones that contains the character C. The result query is: <Where>   <Or>      <And>       <Contains><FieldRef Name='Title' /><Value Type='Text'>A</Value></Contains>       <Contains><FieldRef Name='Title' /><Value Type='Text'>B</Value></Contains>     </And>     <Contains><FieldRef Name='Title' /><Value Type='Text'>C</Value></Contains>   </Or> </Where>     The code:   First of all we have an enumerator inside the CAMLQueryBuilder class that has the two possible Options And, Or. public enum Operators { And, Or }   Then we have the main method that’s the one that performs the append of the filters. public static string AppendQuery(string containerQuery, string logicalExpression, Operators logicalOperator){   In this method the first we do is create a new XmlDocument and wrap the current query (that may be empty) with a “<Query></Query>” tag, because the query that comes with the view doesn’t have a root element and the XmlDocument must be a well formatted xml.   XmlDocument queryDoc = new XmlDocument(); queryDoc.LoadXml("<Query>" + containerQuery + "</Query>");   The next step is to create a new XmlDocument containing the logical expression that has the filter needed.   XmlDocument logicalExpressionDoc = new XmlDocument(); logicalExpressionDoc.LoadXml("<root>" + logicalExpression + "</root>"); In these next four lines we extract the expression from the recently created XmlDocument and create an XmlElement.                  XmlElement expressionElTemp = (XmlElement)logicalExpressionDoc.SelectSingleNode("/root/*"); XmlElement expressionEl = queryDoc.CreateElement(expressionElTemp.Name); expressionEl.InnerXml = expressionElTemp.InnerXml;   Below are the main steps in the component logic. The first “if” checks if the actual query doesn’t contains a “Where” clause. In case there’s no “Where” we add it and append the expression.   In case that there’s already a “Where” clause, we get the entire statement that’s inside the “Where” and reorder the query removing and appending elements to form the correct query, that will finally filter the list.   XmlElement whereEl; if (!containerQuery.Contains("Where")) { queryDoc.FirstChild.AppendChild(queryDoc.CreateElement("Where")); queryDoc.SelectSingleNode("/Query/Where").AppendChild(expressionEl); } else { whereEl = (XmlElement)queryDoc.SelectSingleNode("/Query/Where"); if (!containerQuery.Contains("<And>") &&                 !containerQuery.Contains("<Or>"))        {              XmlElement operatorEl = queryDoc.CreateElement(GetName(logicalOperator)); XmlElement existingExpression = (XmlElement)whereEl.SelectSingleNode("/Query/Where/*"); whereEl.RemoveChild(existingExpression);                 operatorEl.AppendChild(existingExpression);               operatorEl.AppendChild(expressionEl);                 whereEl.AppendChild(operatorEl);        }        else        {              XmlElement operatorEl = queryDoc.CreateElement(GetName(logicalOperator)); XmlElement existingOperator = (XmlElement)whereEl.SelectSingleNode("/Query/Where/*");                 whereEl.RemoveChild(existingOperator);               operatorEl.AppendChild(existingOperator);               operatorEl.AppendChild(expressionEl);                 whereEl.AppendChild(operatorEl);         }  }  return queryDoc.FirstChild.InnerXml }     Finally the GetName method converts the Enum option to his string equivalent.   private static string GetName(Operators logicalOperator) {       return Enum.GetName(typeof(Operators), logicalOperator); }        Normal 0 21 false false false ES-UY X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin-top:0cm; mso-para-margin-right:0cm; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0cm; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} Normal 0 21 false false false ES-UY X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin-top:0cm; mso-para-margin-right:0cm; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0cm; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} This component helped our team a lot using SharePoint 2007 and modifying the queries, but now in SharePoint 2010; that wouldn’t be needed because of the incorporation of LINQ to SharePoint.

  • Highlight Row in GridView with Colored Columns

    - by Vincent Maverick Durano
    I wrote a blog post a while back before here that demonstrate how to highlight a GridView row on mouseover and as you can see its very easy to highlight rows in GridView. One of my colleague uses the same technique for implemeting gridview row highlighting but the problem is that if a Column has background color on it that cell will not be highlighted anymore. To make it more clear then let's build up a sample application. ASPX:   1: <asp:GridView runat="server" id="GridView1" onrowcreated="GridView1_RowCreated" 2: onrowdatabound="GridView1_RowDataBound"> 3: </asp:GridView>   CODE BEHIND:   1: private DataTable FillData() { 2:   3: DataTable dt = new DataTable(); 4: DataRow dr = null; 5:   6: //Create DataTable columns 7: dt.Columns.Add(new DataColumn("RowNumber", typeof(string))); 8: dt.Columns.Add(new DataColumn("Col1", typeof(string))); 9: dt.Columns.Add(new DataColumn("Col2", typeof(string))); 10: dt.Columns.Add(new DataColumn("Col3", typeof(string))); 11:   12: //Create Row for each columns 13: dr = dt.NewRow(); 14: dr["RowNumber"] = 1; 15: dr["Col1"] = "A"; 16: dr["Col2"] = "B"; 17: dr["Col3"] = "C"; 18: dt.Rows.Add(dr); 19:   20: dr = dt.NewRow(); 21: dr["RowNumber"] = 2; 22: dr["Col1"] = "AA"; 23: dr["Col2"] = "BB"; 24: dr["Col3"] = "CC"; 25: dt.Rows.Add(dr); 26:   27: dr = dt.NewRow(); 28: dr["RowNumber"] = 3; 29: dr["Col1"] = "A"; 30: dr["Col2"] = "B"; 31: dr["Col3"] = "CC"; 32: dt.Rows.Add(dr); 33:   34: dr = dt.NewRow(); 35: dr["RowNumber"] = 4; 36: dr["Col1"] = "A"; 37: dr["Col2"] = "B"; 38: dr["Col3"] = "CC"; 39: dt.Rows.Add(dr); 40:   41: dr = dt.NewRow(); 42: dr["RowNumber"] = 5; 43: dr["Col1"] = "A"; 44: dr["Col2"] = "B"; 45: dr["Col3"] = "CC"; 46: dt.Rows.Add(dr); 47:   48: return dt; 49: } 50:   51: protected void Page_Load(object sender, EventArgs e) { 52: if (!IsPostBack) { 53: GridView1.DataSource = FillData(); 54: GridView1.DataBind(); 55: } 56: }   As you can see there's nothing fancy in the code above. It just contain a method that fills a DataTable with a dummy data on it. Now here's the code for row highlighting:   1: protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e) { 2: //Set Background Color for Columns 1 and 3 3: e.Row.Cells[1].BackColor = System.Drawing.Color.Beige; 4: e.Row.Cells[3].BackColor = System.Drawing.Color.Red; 5:   6: //Attach onmouseover and onmouseout for row highlighting 7: e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='Blue'"); 8: e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=''"); 9: }   Running the code above will show something like this in the browser: On initial load: On mouseover of GridView row:   Noticed that Col1 and Col3 are not highlighted. Why? the reason is that Col1 and Col3 cells has background color set on it and we only highlight the rows (TR) and not the columns (TD) that's why on mouseover only the rows will be highlighted. To fix the issue we will create a javascript method that would remove the background color of the columns when highlighting a row and on mouseout set back the original color that is set on Col1 and Col3. Here are the codes below: JavaScript   1: <script type="text/javascript"> 2: function HighLightRow(rowIndex, colIndex,colIndex2, flag) { 3: var gv = document.getElementById("<%= GridView1.ClientID %>"); 4: var selRow = gv.rows[rowIndex]; 5: if (rowIndex > 0) { 6: if (flag == "sel") { 7: gv.rows[rowIndex].style.backgroundColor = 'Blue'; 8: gv.rows[rowIndex].style.color = "White"; 9: gv.rows[rowIndex].cells[colIndex].style.backgroundColor = ''; 10: gv.rows[rowIndex].cells[colIndex2].style.backgroundColor = ''; 11: } 12: else { 13: gv.rows[rowIndex].style.backgroundColor = ''; 14: gv.rows[rowIndex].style.color = "Black"; 15: gv.rows[rowIndex].cells[colIndex].style.backgroundColor = 'Beige'; 16: gv.rows[rowIndex].cells[colIndex2].style.backgroundColor = 'Red'; 17: } 18: } 19: } 20: </script>   The HighLightRow method is a javascript function that accepts four (4) parameters which are the rowIndex,colIndex,colIndex2 and the flag. The rowIndex is the current row index of the selected row in GridView. The colIndex is the index of Col1 and colIndex2 is the index of col3. We are passing these index because these columns has background color on it and we need to toggle its backgroundcolor when highlighting the row in GridView. Finally the flag is something that would determine if its selected or not. Now here's the code for calling the JavaScript function above.     1: protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e) { 2:   3: //Set Background Color for Columns 1 and 3 4: e.Row.Cells[1].BackColor = System.Drawing.Color.Beige; 5: e.Row.Cells[3].BackColor = System.Drawing.Color.Red; 6:   7: //Attach onmouseover and onmouseout for row highlighting 8: //and call the HighLightRow method with the required parameters 9: int index = e.Row.RowIndex + 1; 10: e.Row.Attributes.Add("onmouseover", "HighLightRow(" + index + "," + 1 + "," + 3 + ",'sel')"); 11: e.Row.Attributes.Add("onmouseout", "HighLightRow(" + index + "," + 1 + "," + 3 + ",'dsel')"); 12: 13: }   Running the code above will display something like this: On initial load:   On mouseover of GridView row:   That's it! I hope someone find this post useful!

  • Changing CSS with jQuery syntax in Silverlight using jLight

    - by Timmy Kokke
    Lately I’ve ran into situations where I had to change elements or had to request a value in the DOM from Silverlight. jLight, which was introduced in an earlier article, can help with that. jQuery offers great ways to change CSS during runtime. Silverlight can access the DOM, but it isn’t as easy as jQuery. All examples shown in this article can be looked at in this online demo. The code can be downloaded here.   Part 1: The easy stuff Selecting and changing properties is pretty straight forward. Setting the text color in all <B> </B> elements can be done using the following code:   jQuery.Select("b").Css("color", "red");   The Css() method is an extension method on jQueryObject which is return by the jQuery.Select() method. The Css() method takes to parameters. The first is the Css style property. All properties used in Css can be entered in this string. The second parameter is the value you want to give the property. In this case the property is “color” and it is changed to “red”. To specify which element you want to select you can add a :selector parameter to the Select() method as shown in the next example.   jQuery.Select("b:first").Css("font-family", "sans-serif");   The “:first” pseudo-class selector selects only the first element. This example changes the “font-family” property of the first <B></B> element to “sans-serif”. To make use of intellisense in Visual Studio I’ve added a extension methods to help with the pseudo-classes. In the example below the “font-weight” of every “Even” <LI></LI> is set to “bold”.   jQuery.Select("li".Even()).Css("font-weight", "bold");   Because the Css() extension method returns a jQueryObject it is possible to chain calls to Css(). The following example show setting the “color”, “background-color” and the “font-size” of all headers in one go.   jQuery.Select(":header").Css("color", "#12FF70") .Css("background-color", "yellow") .Css("font-size", "25px");   Part 2: More complex stuff In only a few cases you need to change only one style property. More often you want to change an entire set op style properties all in one go.  You could chain a lot of Css() methods together. A better way is to add a class to a stylesheet and define all properties in there. With the AddClass() method you can set a style class to a set of elements. This example shows how to add the “demostyle” class to all <B></B> in the document.   jQuery.Select("b").AddClass("demostyle");   Removing the class works in the same way:   jQuery.Select("b").RemoveClass("demostyle");   jLight is build for interacting with to the DOM from Silverlight using jQuery. A jQueryObjectCss object can be used to define different sets of style properties in Silverlight. The over 60 most common Css style properties are defined in the jQueryObjectCss class. A string indexer can be used to access all style properties ( CssObject1[“background-color”] equals CssObject1.BackgroundColor). In the code below, two jQueryObjectCss objects are defined and instantiated.   private jQueryObjectCss CssObject1; private jQueryObjectCss CssObject2;   public Demo2() { CssObject1 = new jQueryObjectCss { BackgroundColor = "Lime", Color="Black", FontSize = "12pt", FontFamily = "sans-serif", FontWeight = "bold", MarginLeft = 150, LineHeight = "28px", Border = "Solid 1px #880000" }; CssObject2 = new jQueryObjectCss { FontStyle = "Italic", FontSize = "48", Color = "#225522" }; InitializeComponent(); }   Now instead of chaining to set all different properties you can just pass one of the jQueryObjectCss objects to the Css() method. In this case all <LI></LI> elements are set to match this object.   jQuery.Select("li").Css(CssObject1); When using the jQueryObjectCss objects chaining is still possible. In the following example all headers are given a blue backgroundcolor and the last is set to match CssObject2.   jQuery.Select(":header").Css(new jQueryObjectCss{BackgroundColor = "Blue"}) .Eq(-1).Css(CssObject2);   Part 3: The fun stuff Having Silverlight call JavaScript and than having JavaScript to call Silverlight requires a lot of plumbing code. Everything has to be registered and strings are passed back and forth to execute the JavaScript. jLight makes this kind of stuff so easy, it becomes fun to use. In a lot of situations jQuery can call a function to decide what to do, setting a style class based on complex expressions for example. jLight can do the same, but the callback methods are defined in Silverlight. This example calls the function() method for each <LI></LI> element. The callback method has to take a jQueryObject, an integer and a string as parameters. In this case jLight differs a bit from the actual jQuery implementation. jQuery uses only the index and the className parameters. A jQueryObject is added to make it simpler to access the attributes and properties of the element. If the text of the listitem starts with a ‘D’ or an ‘M’ the class is set. Otherwise null is returned and nothing happens.   private void button1_Click(object sender, RoutedEventArgs e) { jQuery.Select("li").AddClass(function); }   private string function(jQueryObject obj, int index, string className) { if (obj.Text[0] == 'D' || obj.Text[0] == 'M') return "demostyle"; return null; }   The last thing I would like to demonstrate uses even more Silverlight and less jLight, but demonstrates the power of the combination. Animating a style property using a Storyboard with easing functions. First a dependency property is defined. In this case it is a double named Intensity. By handling the changed event the color is set using jQuery.   public double Intensity { get { return (double)GetValue(IntensityProperty); } set { SetValue(IntensityProperty, value); } }   public static readonly DependencyProperty IntensityProperty = DependencyProperty.Register("Intensity", typeof(double), typeof(Demo3), new PropertyMetadata(0.0, IntensityChanged));   private static void IntensityChanged(DependencyObject d, DependencyPropertyChangedEventArgs e) { var i = (byte)(double)e.NewValue; jQuery.Select("span").Css("color", string.Format("#{0:X2}{0:X2}{0:X2}", i)); }   An animation has to be created. This code defines a Storyboard with one keyframe that uses a bounce ease as an easing function. The animation is set to target the Intensity dependency property defined earlier.   private Storyboard CreateAnimation(double value) { Storyboard storyboard = new Storyboard(); var da = new DoubleAnimationUsingKeyFrames(); var d = new EasingDoubleKeyFrame { EasingFunction = new BounceEase(), KeyTime = KeyTime.FromTimeSpan(TimeSpan.FromSeconds(1.0)), Value = value }; da.KeyFrames.Add(d); Storyboard.SetTarget(da, this); Storyboard.SetTargetProperty(da, new PropertyPath(Demo3.IntensityProperty)); storyboard.Children.Add(da); return storyboard; }   Initially the Intensity is set to 128 which results in a gray color. When one of the buttons is pressed, a new animation is created an played. One to animate to black, and one to animate to white.   public Demo3() { InitializeComponent(); Intensity = 128; }   private void button2_Click(object sender, RoutedEventArgs e) { CreateAnimation(255).Begin(); }   private void button3_Click(object sender, RoutedEventArgs e) { CreateAnimation(0).Begin(); }   Conclusion As you can see jLight can make the life of a Silverlight developer a lot easier when accessing the DOM. Almost all jQuery functions that are defined in jLight use the same constructions as described above. I’ve tried to stay as close as possible to the real jQuery. Having JavaScript perform callbacks to Silverlight using jLight will be described in more detail in a future tutorial about AJAX or eventing.

  • Math with Timestamp

    - by Knut Vatsendvik
    table.sql { border-width: 1px; border-spacing: 2px; border-style: dashed; border-color: #0023ff; border-collapse: separate; background-color: white; } table.sql th { border-width: 1px; padding: 1px; border-style: none; border-color: gray; background-color: white; -moz-border-radius: 0px 0px 0px 0px; } table.sql td { border-width: 1px; padding: 3px; border-style: none; border-color: gray; background-color: white; -moz-border-radius: 0px 0px 0px 0px; } .sql-keyword { color: #0000cd; background-color: inherit; } .sql-result { color: #458b74; background-color: inherit; } Got this little SQL quiz from a colleague.  How to add or subtract exactly 1 second from a Timestamp?  Sounded simple enough at first blink, but was a bit trickier than expected. If the data type had been a Date, we knew that we could add or subtract days, minutes or seconds using + or – sysdate + 1 to add one day sysdate - (1 / 24) to subtract one hour sysdate + (1 / 86400) to add one second Would the same arithmetic work with Timestamp as with Date? Let’s test it out with the following query SELECT   systimestamp , systimestamp + (1 / 86400) FROM dual; ---------- 03.05.2010 22.11.50,240887 +02:00 03.05.2010 The first result line shows us the system time down to fractions of seconds. The second result line shows the result as Date (as used for date calculation) meaning now that the granularity is reduced down to a second.   By using the PL/SQL dump() function, we can confirm this with the following query SELECT   dump(systimestamp) , dump(systimestamp + (1 / 86400)) FROM dual; ---------- Typ=188 Len=20: 218,7,5,4,8,53,9,0,200,46,89,20,2,0,5,0,0,0,0,0 Typ=13 Len=8: 218,7,5,4,10,53,10,0 Where typ=13 is a runtime representation for Date. So how can we increase the precision to include fractions of second? After investigating it a bit, we found out that the interval data type INTERVAL DAY TO SECOND could be used with the result of addition or subtraction being a Timestamp. Let’s try again our first query again, now using the interval data type. SELECT systimestamp,    systimestamp + INTERVAL '0 00:00:01.0' DAY TO SECOND(1) FROM dual; ---------- 03.05.2010 22.58.32,723659000 +02:00 03.05.2010 22.58.33,723659000 +02:00 Yes, it worked! To finish the story, here is one example showing how to specify an interval of 2 days, 6 hours, 30 minutes, 4 seconds and 111 thousands of a second. INTERVAL ‘2 6:30:4.111’ DAY TO SECOND(3)

  • GLSL Shader Texture Performance

    - by Austin
    I currently have a project that renders OpenGL video using a vertex and fragment shader. The shaders work fine as-is, but in trying to add in texturing, I am running into performance issues and can't figure out why. Before adding texturing, my program ran just fine and loaded my CPU between 0%-4%. When adding texturing (specifically textures AND color -- noted by comment below), my CPU is 100% loaded. The only code I have added is the relevant texturing code to the shader, and the "glBindTexture()" calls to the rendering code. Here are my shaders and relevant rending code. Vertex Shader: #version 150 uniform mat4 mvMatrix; uniform mat4 mvpMatrix; uniform mat3 normalMatrix; uniform vec4 lightPosition; uniform float diffuseValue; layout(location = 0) in vec3 vertex; layout(location = 1) in vec3 color; layout(location = 2) in vec3 normal; layout(location = 3) in vec2 texCoord; smooth out VertData { vec3 color; vec3 normal; vec3 toLight; float diffuseValue; vec2 texCoord; } VertOut; void main(void) { gl_Position = mvpMatrix * vec4(vertex, 1.0); VertOut.normal = normalize(normalMatrix * normal); VertOut.toLight = normalize(vec3(mvMatrix * lightPosition - gl_Position)); VertOut.color = color; VertOut.diffuseValue = diffuseValue; VertOut.texCoord = texCoord; } Fragment Shader: #version 150 smooth in VertData { vec3 color; vec3 normal; vec3 toLight; float diffuseValue; vec2 texCoord; } VertIn; uniform sampler2D tex; layout(location = 0) out vec3 colorOut; void main(void) { float diffuseComp = max( dot(normalize(VertIn.normal), normalize(VertIn.toLight)) ), 0.0); vec4 color = texture2D(tex, VertIn.texCoord); colorOut = color.rgb * diffuseComp * VertIn.diffuseValue + color.rgb * (1 - VertIn.diffuseValue); // FOLLOWING LINE CAUSES PERFORMANCE ISSUES colorOut *= VertIn.color; } Relevant Rendering Code: // 3 textures have been successfully pre-loaded, and can be used // texture[0] is a 1x1 white texture to effectively turn off texturing glUseProgram(program); // Draw squares glBindTexture(GL_TEXTURE_2D, texture[1]); // Set attributes, uniforms, etc glDrawArrays(GL_QUADS, 0, 6*4); // Draw triangles glBindTexture(GL_TEXTURE_2D, texture[0]); // Set attributes, uniforms, etc glDrawArrays(GL_TRIANGLES, 0, 3*4); // Draw reference planes glBindTexture(GL_TEXTURE_2D, texture[0]); // Set attributes, uniforms, etc glDrawArrays(GL_LINES, 0, 4*81*2); // Draw terrain glBindTexture(GL_TEXTURE_2D, texture[2]); // Set attributes, uniforms, etc glDrawArrays(GL_TRIANGLES, 0, 501*501*6); // Release glBindTexture(GL_TEXTURE_2D, 0); glUseProgram(0); Any help is greatly appreciated!

  • pyQt4: QWidget subclass not responding to new setStyleSheet() background colour

    - by Ronny
    I am having an issue with PyQt4. I want to create a new widget within a window, and I want this widget to have a custom color. When i create a subclass of the QWidget class, and instantiate it, I am not able to change its background color through the setStyleSheet() function. When I instantiate a new QWidget object, I have no problems in changing its background color. But i dont want an ordinary QWidget object.I want to create my own subclass of QWidget. When i create a subclass of a QPushButton, I am also able to change its background color using the setStyleSheet() function. There are no error messages or warnings in the console window, it just refuses to work properly without any indication as to why. So what i would like to know is why is it that i can change the background color of a widget if i simply create a QWidget object, or a subclass of QPushButton, but not when i create a subclass of QWidget. And how can i therefore change the background color of an object that is a subclass of QWidget? Is it maybe something specific to the version of python or PyQt that i am using? Is it a bug in the library? or some flaw in the way that i am writing my code? I am using python 2.6.4 and PyQt4 Below is an example of the code that leads me to trouble. There are three widgets within the window one below the other. The parent widget is set with background color of green. The top widget is set to red, the middle one, is the subclass of QWidget, which should be blue, but it appears invisible because it takes on the color of the parent window for some reason. and the bottom widget is a subclass of QPushButton and is white. import sys from PyQt4 import QtGui, QtCore ################################################################################ #--------------------------------------------------------- CUSTOM WIDGET CLASS 1 class CustomWidget(QtGui.QWidget): def __init__(self, parent): QtGui.QWidget.__init__(self, parent) # some custom properties and functions will follow ################################################################################ #--------------------------------------------------------- CUSTOM WIDGET CLASS 2 class CustomWidget2(QtGui.QPushButton): def __init__(self, parent): QtGui.QPushButton.__init__(self, parent) # some custom properties and functions will follow ################################################################################ #----------------------------------------------------------- PARENT WIDGET CLASS class Parent(QtGui.QWidget): def __init__(self, parent=None): #---------------------------------------------------------- SETUP WINDOW QtGui.QWidget.__init__(self, parent) self.resize(500, 340) self.setStyleSheet("QWidget {background-color: #00FF00}") #-------------------------------------------------- SETUP DEFAULT WIDGET wid1 = QtGui.QWidget(self) wid1.setGeometry(10, 10, 480, 100) wid1.setStyleSheet("QWidget {background-color: #FF0000 }") #------------------------------------------------- SETUP CUSTOM WIDGET 1 wid2 = CustomWidget(self) wid2.setGeometry(10, 120, 480, 100) wid2.setStyleSheet("QWidget {background-color: #0000FF }") for i in dir(wid2): print i #------------------------------------------------- SETUP CUSTOM WIDGET 2 wid3 = CustomWidget2(self) wid3.setGeometry(10, 230, 480, 100) wid3.setStyleSheet("QWidget {background-color: #FFFFFF }") ################################################################################ #-------------------------------------------------------------------------- MAIN app = QtGui.QApplication(sys.argv) win = Parent() win.show() app.exec_()

  • Setting treeview background color in VB6 has a flaw - help?

    - by RenMan
    I have successfully implemented this method of using the Win32 API to set the background color of a treeview in VB 6: http://support.microsoft.com/kb/178491 However, one thing goes wrong: when you expand the tree nodes more than two levels deep, the area to the left of (and sometimes under) the inner plus [+] and minus [-] signs is still white. Does anyone know how to get this area to the correct background color, too? Note: I'm also setting the BackColor of each node, and also the BackColor of the treeview's imagelist. Here's my version of the code: Public Sub TreeView_SetBackgroundColor(TreeView As MSComctlLib.TreeView, BackgroundColor As Long) Dim lStyle As Long, Node As MSComctlLib.Node For Each Node In TreeView.Nodes Node.BackColor = BackgroundColor Next TreeView.ImageList.BackColor = BackgroundColor Call SendMessage( _ TreeView.hwnd, _ TVM_SETBKCOLOR, _ 0, _ ByVal BackgroundColor) 'Now reset the style so that the tree lines appear properly. lStyle = GetWindowLong(TreeView.hwnd, GWL_STYLE) Call SetWindowLong(TreeView.hwnd, GWL_STYLE, lStyle - TVS_HASLINES) Call SetWindowLong(TreeView.hwnd, GWL_STYLE, lStyle) End Sub
