• Silverlight ItemsControl vertical scrollbar, using a wrappanel as ControlTemplate

  - by Orestes C.A.

  I have a collection of elements, each one with a name and a subcollection of image blobs. I want to display an Accordion, with each item representing each of the MainElements. inside each element, I display the images in the subcollecion of said MainElement. The Accordion gets resized by the user, so I use a wrappanel for presenting the images. When the accordion is wide enough, the images reorder themselves fitting as many as posible in each row. the problem comes when the wrappanel only displays one image per row (because there's no space enough for more), the image list continues, but I can't see all the images, because they don't fit inside the control's height. I need a vertical scrollbar to be displayed inside the AccordionItem so I can scroll down the image list. So, here's my code: <layoutToolkit:Accordion Width="Auto" Height="Auto" ItemsSource="{Binding MainElementCollection}"> <layoutToolkit:Accordion.ItemTemplate> <DataTemplate> <TextBlock Text="{Binding MainElementName}" /> </DataTemplate> </layoutToolkit:Accordion.ItemTemplate> <layoutToolkit:Accordion.ContentTemplate> <DataTemplate> <ItemsControl ItemsSource="{Binding SubElementCollection}" ScrollViewer.VerticalScrollBarVisibility="Auto" > <ItemsControl.Template> <ControlTemplate> <controlsToolkit:WrapPanel /> </ControlTemplate> </ItemsControl.Template> <ItemsControl.ItemTemplate> <DataTemplate> <Grid> <Image Margin="2" Width="150" Source="{Binding PreviewImage, Converter={StaticResource ImageConverter}}" /> </Grid> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> </DataTemplate> </layoutToolkit:Accordion.ContentTemplate> </layoutToolkit:Accordion> http://www.silverlightshow.net/tips/How-to-add-scrollbars-to-ItemsControl.aspx suggests that I should surround my wrappanel with a scrollviewer, like this <ItemsControl.Template> <ControlTemplate> <scrollviewer> <controlsToolkit:WrapPanel /> </scrollviewer> </ControlTemplate> </ItemsControl.Template> But then my wrappanel gets really small and I can only see a small vertical scrollbar Any ideas? Thanks a lot. Edit: I figured thatthe wrappanel loses its width when used in the controltemplate It should be used as follows: <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <controlsToolkit:WrapPanel ScrollViewer.VerticalScrollBarVisibility="Visible" /> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> Anyway, I tried adding the ScrollViewer.VerticalScrollBarVisibility="Visible" line but I'm stuck again.

• Flash CS3 -- tahoma text loading differently than on client's computer.

  - by codemonkey613

  A client has sent me a Flash CS3 website template she was working on. I'm supposed to do some work on it. When I load it, it displays incorrectly. The body type appears incorrectly. It's different then what it appears on her computer. Causing all the body text to overlap each other. She has Windows Vista with Flash CS3. I'm using Windows XP Professional with Flash CS4. When I open the file, it says that 'tahoma' font is missing on my computer. And asks me to select a replacement. Obviously, I have Tahoma on my computer -- everyone does. I even got her to send her version of Tahoma to me from her Windows Font Folder. When I tried to install it, it says "font already installed". So, I pointed it to my Tahoma font as a replacement. This could be the problem. But why does it not recognize my version of tahoma? Anyone know what's going on, or how I can fix it? I'm supposed to be working on this website, but can't proceed because I might be wasting time if it doesn't match up.

• optimizing iPhone OpenGL ES fill rate

  - by NateS

  I have an Open GL ES game on the iPhone. My framerate is pretty sucky, ~20fps. Using the Xcode OpenGL ES performance tool on an iPhone 3G, it shows: Renderer Utilization: 95% to 99% Tiler Utilization: ~27% I am drawing a lot of pretty large images with a lot of blending. If I reduce the number of images drawn, framerates go from ~20 to ~40, though the performance tool results stay about the same (renderer still maxed). I think I'm being limited by the fill rate of the iPhone 3G, but I'm not sure. My questions are: How can I determine with more granularity where the bottleneck is? That is my biggest problem, I just don't know what is taking all the time. If it is fillrate, is there anything I do to improve it besides just drawing less? I am using texture atlases. I have tried to minimize image binds, though it isn't always possible (drawing order, not everything fits on one 1024x1024 texture, etc). Every frame I do 10 image binds. This seem pretty reasonable, but I could be mistaken. I'm using vertex arrays and glDrawArrays. I don't really have a lot of geometry. I can try to be more precise if needed. Each image is 2 triangles and I try to batch things were possible, though often (maybe half the time) images are drawn with individual glDrawArrays calls. Besides the images, I have ~60 triangles worth of geometry being rendered in ~6 glDrawArrays calls. I often glTranslate before calling glDrawArrays. Would it improve the framerate to switch to VBOs? I don't think it is a huge amount of geometry, but maybe it is faster for other reasons? Are there certain things to watch out for that could reduce performance? Eg, should I avoid glTranslate, glColor4g, etc? I'm using glScissor in a 3 places per frame. Each use consists of 2 glScissor calls, one to set it up, and one to reset it to what it was. I don't know if there is much of a performance impact here. If I used PVRTC would it be able to render faster? Currently all my images are GL_RGBA. I don't have memory issues. Here is a rough idea of what I'm drawing, in this order: 1) Switch to perspective matrix. 2) Draw a full screen background image 3) Draw a full screen image with translucency (this one has a scrolling texture). 4) Draw a few sprites. 5) Switch to ortho matrix. 6) Draw a few sprites. 7) Switch to perspective matrix. 8) Draw sprites and some other textured geometry. 9) Switch to ortho matrix. 10) Draw a few sprites (eg, game HUD). Steps 1-6 draw a bunch of background stuff. 8 draws most of the game content. 10 draws the HUD. As you can see, there are many layers, some of them full screen and some of the sprites are pretty large (1/4 of the screen). The layers use translucency, so I have to draw them in back-to-front order. This is further complicated by needing to draw various layers in ortho and others in perspective. I will gladly provide additional information if reqested. Thanks in advance for any performance tips or general advice on my problem!

• In WPF, Selecting ItemContainerStyle based on data bound content

  - by Bart Roozendaal

  In #WPF you have ItemTemplateSelectors. But, can you also select an ItemContainerStyle based on the datatype of a bound object? I am databinding a scatterview. I want to set some properties of the generated ScatterViewItems based on the object in their DataContext. A mechanism similar to ItemTemplateSelector for styles would be great. Is that at all possible? I am now binding to properties in the objects that I am displaying to get the effect, but that feels like overhead and too complex (and most importantly, something that our XU designers can't do by themselves). This is the XAML that I am using now. Your help is greatly appreciated. <s:ScatterView x:Name="topicsViewer"> <s:ScatterView.ItemTemplateSelector> <local:TopicViewerDataTemplateSelector> <DataTemplate DataType="{x:Type mvc:S7VideoTopic}"> <Grid> <ContentPresenter Content="{Binding MediaElement}" /> <s:SurfaceButton Visibility="{Binding MailToVisible}" x:Name="mailto" Tag="{Binding Titel}" Click="mailto_Click" HorizontalAlignment="Right" VerticalAlignment="Top" Background="Transparent" Width="62" Height="36"> <Image Source="/Resources/MailTo.png" /> </s:SurfaceButton> <StackPanel Orientation="Horizontal" VerticalAlignment="Bottom" HorizontalAlignment="Center" Height="32"> <s:SurfaceButton Tag="{Binding MediaElement}" x:Name="btnPlay" Click="btnPlay_Click"> <Image Source="/Resources/control_play.png" /> </s:SurfaceButton> <s:SurfaceButton Tag="{Binding MediaElement}" x:Name="btnPause" Click="btnPause_Click"> <Image Source="/Resources/control_pause.png" /> </s:SurfaceButton> <s:SurfaceButton Tag="{Binding MediaElement}" x:Name="btnStop" Click="btnStop_Click"> <Image Source="/Resources/control_stop.png" /> </s:SurfaceButton> </StackPanel> </Grid> </DataTemplate> <DataTemplate DataType="{x:Type mvc:S7ImageTopic}"> <Grid> <ContentPresenter Content="{Binding Resource}" /> <s:SurfaceButton Visibility="{Binding MailToVisible}" x:Name="mailto" Tag="{Binding Titel}" Click="mailto_Click" HorizontalAlignment="Right" VerticalAlignment="Top" Background="Transparent" Width="62" Height="36"> <Image Source="/Resources/MailTo.png" /> </s:SurfaceButton> </Grid> </DataTemplate> <DataTemplate DataType="{x:Type local:Kassa}"> <ContentPresenter Content="{Binding}" Width="300" Height="355" /> </DataTemplate> </local:TopicViewerDataTemplateSelector> </s:ScatterView.ItemTemplateSelector> <s:ScatterView.ItemContainerStyle> <Style TargetType="s:ScatterViewItem"> <Setter Property="MinWidth" Value="200" /> <Setter Property="MinHeight" Value="150" /> <Setter Property="MaxWidth" Value="800" /> <Setter Property="MaxHeight" Value="700" /> <Setter Property="Width" Value="{Binding DefaultWidth}" /> <Setter Property="Height" Value="{Binding DefaultHeight}" /> <Setter Property="s:ScatterViewItem.CanMove" Value="{Binding CanMove}" /> <Setter Property="s:ScatterViewItem.CanScale" Value="{Binding CanScale}" /> <Setter Property="s:ScatterViewItem.CanRotate" Value="{Binding CanRotate}" /> <Setter Property="Background" Value="Transparent" /> </Style> </s:ScatterView.ItemContainerStyle> </s:ScatterView> Bart Roozendaal, Sevensteps

• The nexus of MSDeploy, MSBuild and Hudson

  - by roufamatic

  Hey, I have experience with MSBuild and Hudson, but am new to MSDeploy. I currently have a simple solution with one web application project. I set up a build configuration and am using the "Publish" command (Visual Studio 2010) to simply copy files to a local folder and do config file replacement. What I would like to do is automate this using Hudson. So I figure I'll create an MSBuild script that will Perform the build (by calling out to the project file with my desired build configuration) Call MSDeploy to do all the same things that the "Publish" command is doing, except copy the files to a different folder. Configure Hudson to poll subversion and perform steps 1 & 2 when changes are detected Step 2 is where I'm getting lost. I assumed that the project.xml file that was created by VS2010 corresponded to -verb:sync -source:manifest=project.xml options, but msdeploy is choking on that xml file so clearly that's not what it's intended for. What command is Visual Studio executing under the covers to perform the config file replacement and the file copy? How do I automate the Publish command?

• Replace text in word textbox objects using VSTO and C#

  - by Roberto

  Hi, I have to find/replace text from a word document. It works fine for plain text spread through the document, however when the text is in a textbox, the standard find/replace approach doesn't reach it. I found a vba solution, however since I am working in C#, I would like to find a solution in C#. The word document is in 2007 format and my visual studio is 2010. I am using .Net Framework 3.5, but if required, I can consider moving to 4.0. Here is the code for the find/replace that only works with plain text (not in word textbox objects): object Missing = System.Reflection.Missing.Value; object fileToOpen = (object)@"c:\doc.docx"; object fileToSave = (object)@"c:\doc.docx"; Word.Application app = new Word.ApplicationClass(); Word.Document doc = new Word.Document(); try { doc = app.Documents.Open(ref fileToOpen, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing); object replaceAll = Word.WdReplace.wdReplaceAll; app.Selection.Find.ClearFormatting(); app.Selection.Find.Text = "MyTextForReplacement"; app.Selection.Find.Replacement.ClearFormatting(); app.Selection.Find.Replacement.Text = "Found you!"; app.Selection.Find.Execute( ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref replaceAll, ref Missing, ref Missing, ref Missing, ref Missing); I also tried using the below code, but didn't work as well: foreach(Word.Shape s in app.ActiveDocument.Shapes) { if(s.TextFrame.HasText >= 1) //The value is always 0 or -1, and even leaving 0 go forward, // it doesn't work, because there is no text in there... { foreach(Word.Field f in s.TextFrame.TextRange.Fields) { switch( f.Type) { . . //I never reached this point . } } } Any help will be appreciated... Thanks, -- Roberto Lopes

  I m making App in java using Swing component and JAI library.

• TableViewCell autorelease error

  - by iAm

  OK, for two days now i have been trying to solve an error i have inside the cellForRowAtIndex method, let start by saying that i have tracked down the bug to this method, the error is [CFDictionary image] or [Not a Type image] message sent to deallocated instance. I know about the debug flags, NSZombie, MallocStack, and others, they helped me narrow it down to this method and why, but I do not know how to solve besides a redesign of the app UI. SO what am i trying to do, well for this block of code, displays a purchase detail, which contains items, the items are in there own section, now when in edit mode, there appears a cell at the bottom of the items section with a label of "Add new Item", and this button will present a modal view of the add item controller, item is added and the view returns to the purchase detail screen, with the just added item in the section just above the "add new Item" cell, the problem happens when i scroll the item section off screen and back into view the app crashes with EXC_BAD_ACCESS, or even if i don't scroll and instead hit the back button on the navBar, still the same error. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = nil; switch (indexPath.section) { case PURCHASE_SECTION: { static NSString *cellID = @"GenericCell"; cell = [tableView dequeueReusableCellWithIdentifier:cellID]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue2 reuseIdentifier:cellID] autorelease]; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; } switch (indexPath.row) { case CATEGORY_ROW: cell.textLabel.text = @"Category:"; cell.detailTextLabel.text = [self.purchase.category valueForKey:@"name"]; cell.accessoryType = UITableViewCellAccessoryNone; cell.editingAccessoryType = UITableViewCellAccessoryDisclosureIndicator; break; case TYPE_ROW: cell.textLabel.text = @"Type:"; cell.detailTextLabel.text = [self.purchase.type valueForKey:@"name"]; cell.accessoryType = UITableViewCellAccessoryNone; cell.editingAccessoryType = UITableViewCellAccessoryDisclosureIndicator; break; case VENDOR_ROW: cell.textLabel.text = @"Payment:"; cell.detailTextLabel.text = [self.purchase.vendor valueForKey:@"name"]; cell.accessoryType = UITableViewCellAccessoryNone; cell.editingAccessoryType = UITableViewCellAccessoryDisclosureIndicator; break; case NOTES_ROW: cell.textLabel.text = @"Notes"; cell.editingAccessoryType = UITableViewCellAccessoryNone; break; default: break; } break; } case ITEMS_SECTION: { NSUInteger itemsCount = [items count]; if (indexPath.row < itemsCount) { static NSString *itemsCellID = @"ItemsCell"; cell = [tableView dequeueReusableCellWithIdentifier:itemsCellID]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:itemsCellID] autorelease]; cell.accessoryType = UITableViewCellAccessoryNone; } singleItem = [self.items objectAtIndex:indexPath.row]; cell.textLabel.text = singleItem.name; cell.detailTextLabel.text = [singleItem.amount formattedDataDisplay]; cell.imageView.image = [singleItem.image image]; } else { static NSString *AddItemCellID = @"AddItemCell"; cell = [tableView dequeueReusableCellWithIdentifier:AddItemCellID]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:AddItemCellID] autorelease]; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; } cell.textLabel.text = @"Add Item"; } break; } case LOCATION_SECTION: { static NSString *localID = @"LocationCell"; cell = [tableView dequeueReusableCellWithIdentifier:localID]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:localID] autorelease]; cell.accessoryType = UITableViewCellAccessoryNone; } cell.textLabel.text = @"Purchase Location"; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; cell.editingAccessoryType = UITableViewCellAccessoryNone; break; } default: break; } return cell; } the singleItem is of Modal Type PurchaseItem for core data now that i know what is causing the error, how do i solve it, I have tried everything that i know and some of what i dont know but still, no progress, please any suggestions as to how to solve this without redesign is my goal, perhaps there is an error i am doing that I cannot see, but if it's the nature of autorelease, than i will redesign.

• Python win32com - Automating Word - How to replace text in a text box?

  - by Greg

  I'm trying to automate word to replace text in a word document using Python. (I'm on word 2003 if that matters and Python 2.4) The first part of my replace method below works on everything except text in text boxes. The text just doesn't get selected. I notice when I go into Word manually and hit ctrl-A all of the text gets selected except for the text box. Here's my code so far: class Word: def __init__(self,visible=0,screenupdating=0): pythoncom.CoInitialize() self.app=gencache.EnsureDispatch(WORD) self.app.Visible = visible self.app.DisplayAlerts = 0 self.app.ScreenUpdating = screenupdating print 'Starting word' def open(self,doc): self.opendoc=os.path.basename(doc) self.app.Documents.Open(FileName=doc) def replace(self,source,target): if target=='':target=' ' alltext=self.app.Documents(self.opendoc).Range(Start=0,End=self.app.Documents(self.opendoc).Characters.Count) #select all alltext.Find.Text = source alltext.Find.Replacement.Text = target alltext.Find.Execute(Replace=1,Forward=True) #Special handling to do replace in text boxes #http://word.tips.net/Pages/T003879_Updating_a_Field_in_a_Text_Box.html for shp in self.app.Documents(self.opendoc).Shapes: if shp.TextFrame.HasText: shp.TextFrame.TextRange.Find.Text = source shp.TextFrame.TextRange.Find.Replacement.Text = target shp.TextFrame.TextRange.Find.Execute(Replace=1,Forward=True) #My Usage word=Word(visible=1,screenupdating=1) word.open(r'C:\Invoice Automation\testTB.doc') word.replace('[PGN]','1') The for shp in self.app .. section is my attempt to hit the text boxes. It seems to find the text box, but it doesn't replace anything.

• Changing FileNames using RegEx and Recursion

  - by yeahumok

  Hello I'm trying to rename files that my program lists as having "illegal characters" for a SharePoint file importation. The illegal characters I am referring to are: ~ # % & * {} / \ | : < ? - "" What i'm trying to do is recurse through the drive, gather up a list of filenames and then through Regular Expressions, pick out file names from a List and try to replace the invalid characters in the actual filenames themselves. Anybody have any idea how to do this? So far i have this: (please remember, i'm a complete n00b to this stuff) class Program { static void Main(string[] args) { string[] files = Directory.GetFiles(@"C:\Documents and Settings\bob.smith\Desktop\~Test Folder for [SharePoint] %testing", "*.*", SearchOption.AllDirectories); foreach (string file in files) { Console.Write(file + "\r\n"); } Console.WriteLine("Press any key to continue..."); Console.ReadKey(true); string pattern = " *[\\~#%&*{}/:<>?|\"-]+ *"; string replacement = " "; Regex regEx = new Regex(pattern); string[] fileDrive = Directory.GetFiles(@"C:\Documents and Settings\bob.smith\Desktop\~Test Folder for [SharePoint] %testing", "*.*", SearchOption.AllDirectories); StreamWriter sw = new StreamWriter(@"C:\Documents and Settings\bob.smith\Desktop\~Test Folder for [SharePoint] %testing\File_Renames.txt"); foreach(string fileNames in fileDrive) { string sanitized = regEx.Replace(fileNames, replacement); sw.Write(sanitized + "\r\n"); } sw.Close(); } } So what i need to figure out is how to recursively search for these invalid chars, replace them in the actual filename itself. Anybody have any ideas?

• Disable antialiasing for a specific GDI device context

  - by Jacob Stanley

  I'm using a third party library to render an image to a GDI DC and I need to ensure that any text is rendered without any smoothing/antialiasing so that I can convert the image to a predefined palette with indexed colors. The third party library i'm using for rendering doesn't support this and just renders text as per the current windows settings for font rendering. They've also said that it's unlikely they'll add the ability to switch anti-aliasing off any time soon. The best work around I've found so far is to call the third party library in this way (error handling and prior settings checks ommitted for brevity): private static void SetFontSmoothing(bool enabled) { int pv = 0; SystemParametersInfo(Spi.SetFontSmoothing, enabled ? 1 : 0, ref pv, Spif.None); } // snip Graphics graphics = Graphics.FromImage(bitmap) IntPtr deviceContext = graphics.GetHdc(); SetFontSmoothing(false); thirdPartyComponent.Render(deviceContext); SetFontSmoothing(true); This obviously has a horrible effect on the operating system, other applications flicker from cleartype enabled to disabled and back every time I render the image. So the question is, does anyone know how I can alter the font rendering settings for a specific DC? Even if I could just make the changes process or thread specific instead of affecting the whole operating system, that would be a big step forward! (That would give me the option of farming this rendering out to a separate process- the results are written to disk after rendering anyway) EDIT: I'd like to add that I don't mind if the solution is more complex than just a few API calls. I'd even be happy with a solution that involved hooking system dlls if it was only about a days work. EDIT: Background Information The third-party library renders using a palette of about 70 colors. After the image (which is actually a map tile) is rendered to the DC, I convert each pixel from it's 32-bit color back to it's palette index and store the result as an 8bpp greyscale image. This is uploaded to the video card as a texture. During rendering, I re-apply the palette (also stored as a texture) with a pixel shader executing on the video card. This allows me to switch and fade between different palettes instantaneously instead of needing to regenerate all the required tiles. It takes between 10-60 seconds to generate and upload all the tiles for a typical view of the world. EDIT: Renamed GraphicsDevice to Graphics The class GraphicsDevice in the previous version of this question is actually System.Drawing.Graphics. I had renamed it (using GraphicsDevice = ...) because the code in question is in the namespace MyCompany.Graphics and the compiler wasn't able resolve it properly. EDIT: Success! I even managed to port the PatchIat function below to C# with the help of Marshal.GetFunctionPointerForDelegate. The .NET interop team really did a fantastic job! I'm now using the following syntax, where Patch is an extension method on System.Diagnostics.ProcessModule: module.Patch( "Gdi32.dll", "CreateFontIndirectA", (CreateFontIndirectA original) => font => { font->lfQuality = NONANTIALIASED_QUALITY; return original(font); }); private unsafe delegate IntPtr CreateFontIndirectA(LOGFONTA* lplf); private const int NONANTIALIASED_QUALITY = 3; [StructLayout(LayoutKind.Sequential)] private struct LOGFONTA { public int lfHeight; public int lfWidth; public int lfEscapement; public int lfOrientation; public int lfWeight; public byte lfItalic; public byte lfUnderline; public byte lfStrikeOut; public byte lfCharSet; public byte lfOutPrecision; public byte lfClipPrecision; public byte lfQuality; public byte lfPitchAndFamily; public unsafe fixed sbyte lfFaceName [32]; }

• Maven String Replace of Text Web Resources

  - by Jaco van Niekerk

  I have a Maven web application with text files in src/main/webapp/textfilesdir As I understand it, during the package phase this textfilesdir directory will be copied into the target/project-1.0-SNAPSHOT directory, which is then zipped up into a target/project-1.0-SNAPSHOT.war Problem Now, I need to do a string replacement on the contents of the text files in target/project-1.0-SNAPSHOT/textfilesdir. This must then be done after the textfilesdir is copied into target/project-1.0-SNAPSHOT, but prior to the target/project-1.0-SNAPSHOT.war file being created. I believe this is all done during the package phase. How can a plugin (potentially maven-antrun-plugin), plug into the package phase to do this. The text files don't contain properties, like ${property-name} to filter on. String replacement is likely the only option. Options Modify the text files after the copy into target/project-1.0-SNAPSHOT directory, yet prior to the WAR creation. After packaging, extract the text files from WAR, modify them, and add them back into the WAR. I'm thinking there is another option here I'm missing. Thoughts anyone?

• css, unordered list not displaying icon in right place...

  - by Ronedog

  I'm really frustrated with this one. A few weeks ago I got it working in both firefox and ie just fine. Went back today to do some testing and found a problem with the display in firefox and I've been searching the code but can't find anything. I could use a few tips from anyone willing, I'm sure I'm looking at the wrong things. I upgraded my firefox version but I imagine my code is broke, not firefox. I'm assuming the problem is somewhere in my css file, but I'm not sure. Here's what I've confirmed so far. There don't seem to be conflicts in other css files with < ul 's or < li 's that may be overriding settings. The other confirmation is that This works fine in Internet Explorer...therefore I must be an idiot, because its usually been the other way around (working in FF, but failing in IE). Here's How it looks in IE (Notice the position of the folder icon right next to the text): Here's how it looks in FF (Notice the folder icon is not being pushed down with its corresponding text). Here's the Unordered List: <ul id="nav"> <li><a>Utah</a></li> <ul> <li><a>ParkCity</a> <ul> <li><a>Com1</a></li> <ul> <li class="folder_closed"><a>Timber</a></li> <div>SQUARE CONTAINER IS INSIDE THIS DIV</div> </ul> </ul> </ul> </ul> Here's the CSS that is used for the whole menu: /* MENU NAVIGATION (<UL><LI> LISTS ****************************************/ ul#nav{ /* This handles the main root <ul> */ margin-left:0; margin-right:0; padding-left:0px; text-indent:15px; } ul#nav div{ overflow: hidden; } #nav li>a:hover { cursor: pointer; } #nav li > ul{ /* This will hide any element with an id of "nav" and an "li" that has a direct child that is a "ul" */ display:none; margin-left:0px; margin-right:0px; padding-left:15px; padding-right:0px; text-indent:15px; } #nav li { list-style-type:none; list-style-image: none; } #nav > li{ vertical-align: top; left:0px; text-align:left; clear: both; margin:0px; margin-right:0px; padding-right:0px; } .menu_parent{ background-image: url(../images/maximize.png); background-repeat: no-repeat; background-position: 0px 1px; position:relative; } .menu_parent_minimized{ background-image: url(../images/minimize.png); background-repeat: no-repeat; background-position: 0px 1px; position:relative; } .folder_closed{ position:relative; background-image: url(../images/folder_closed12x14.png); background-repeat: no-repeat; background-position: 0px -2px; } .folder_open{ position:relative; background-image: url(../images/folder_open12x14.png); background-repeat: no-repeat; background-position: 0px -2px; } </ul>

• Multiple calls to preg_replace alters result

  - by Hurpe

  I have a bunch of files that were named in a somewhat standard format. The standard form is basically this: [integer]_word1_word2_word3_ ... _wordn where a word could really be anything, but all words are separated by an underscore. There is really only 3 things I want to do to the text: 1.) I want to modify the integer, which is always at the beginning, so that something like "200" would become $ 200.00. 2.) replace any "words" of the form "with", "With", "w/", or "W/" with "with". 3.) Replace all underscores with a space. I wrote three different preg_replace calls to do the trick. They are as follows: 1.) $filename = preg_replace("/(^[0-9]+)/","$ $1.00",$filename) 2.) $filename = preg_replace("/_([wW]|[wW]ith)_/"," with ",$filename) 3.) $filename = preg_replace("/_/"," ",$filename); Each replacement works as expected when run individually, but when all three are run, the 2nd replacement is ignored. Why would something like that occur? Thanks for the help!

• Using Interop.Word, is there a way to do a replace (using Find.Execute) and keep the original text's

  - by AJ

  I'm attempting to write find/replace code for Word documents using Word Automation through Interop.Word (11.0). My documents all have various fields (that don't show up in Document.Fields) that are surrounded with brackets, eg., <DATE> needs to be replaced with DateTime.Now.Format("MM/dd/yyyy"). The find/replace works fine. However, some of the text being replaced is right-justified, and upon replacement, the text wraps to the next line. Is there any way that I can keep the justification when I perform the replace? Code is below: using Word = Microsoft.Office.Interop.Word; Word.Application wordApp = null; try { wordApp = new Word.Application {Visible = false}; //.... open the document .... object unitsStory = Word.WdUnits.wdStory; object moveType = Word.WdMovementType.wdMove; wordApp.Selection.HomeKey(ref unitsStory, ref moveType); wordApp.Selection.Find.ClearFormatting(); wordApp.Selection.Find.Replacement.ClearFormatting(); //tried removing this, no luck object replaceTextWith = DateTime.Now.ToString("MM/dd/yyyy"); object textToReplace = "<DATE>"; object replaceAll = Word.WdReplace.wdReplaceAll; object typeMissing = System.Reflection.Missing.Value; wordApp.Selection.Find.Execute(ref textToReplace, ref typeMissing, ref typeMissing, ref typeMissing, ref typeMissing, ref typeMissing, ref typeMissing, ref typeMissing, ref typeMissing, ref typeMissing, ref replaceTextWith, ref replaceAll, ref typeMissing, ref typeMissing, ref typeMissing, ref typeMissing); // ... save quit etc.... } finally { //clean up wordApp } TIA.

• All UITableCells rendered at once... why?

  - by Greg

  I'm extremely confused by the proper behavior of UITableView cell rendering. Here's the situation: I have a list of 250 items that are loading into a table view, each with an image. To optimize the image download, I followed along with Apple's LazyTableImages sample code... pretty much following it exactly. Really good system... for reference, here's the cell renderer within the Apple sample code: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { // customize the appearance of table view cells // static NSString *CellIdentifier = @"LazyTableCell"; static NSString *PlaceholderCellIdentifier = @"PlaceholderCell"; // add a placeholder cell while waiting on table data int nodeCount = [self.entries count]; if (nodeCount == 0 && indexPath.row == 0) { UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:PlaceholderCellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:PlaceholderCellIdentifier] autorelease]; cell.detailTextLabel.textAlignment = UITextAlignmentCenter; cell.selectionStyle = UITableViewCellSelectionStyleNone; } cell.detailTextLabel.text = @"Loading…"; return cell; } UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease]; cell.selectionStyle = UITableViewCellSelectionStyleNone; } // Leave cells empty if there's no data yet if (nodeCount > 0) { // Set up the cell... AppRecord *appRecord = [self.entries objectAtIndex:indexPath.row]; cell.textLabel.text = appRecord.appName; cell.detailTextLabel.text = appRecord.artist; // Only load cached images; defer new downloads until scrolling ends if (!appRecord.appIcon) { if (self.tableView.dragging == NO && self.tableView.decelerating == NO) { [self startIconDownload:appRecord forIndexPath:indexPath]; } // if a download is deferred or in progress, return a placeholder image cell.imageView.image = [UIImage imageNamed:@"Placeholder.png"]; } else { cell.imageView.image = appRecord.appIcon; } } return cell; } So – my implementation of Apple's LazyTableImages system has one crucial flaw: it starts all downloads for all images immediately. Now, if I remove this line: //[self startIconDownload:appRecord forIndexPath:indexPath]; Then the system behaves exactly like you would expect: new images load as their placeholders scroll into view. However, the initial view cells do not automatically load their images without that prompt in the cell renderer. So, I have a problem: with the prompt in the cell renderer, all images load at once. Without the prompt, the initial view doesn't load. Now, this works fine in Apple sample code, which got me wondering what was going on with mine. It's almost like it was building all cells up front rather than just the 8 or so that would appear within the display. So, I got looking into it, and this is indeed the case... my table is building 250 unique cells! I didn't think the UITableView worked like this, I guess I thought it only built as many items as were needed to populate the table. Is this the case, or is it correct that it would build all 250 cells up front? Also – related question: I've tried to compare my implementation against the Apple LazyTableImages sample, but have discovered that NSLog appears to be disabled within the Apple sample code (which makes direct behavior comparisons extremely difficult). Is that just a simple publish setting somewhere, or has Apple somehow locked down their samples so that you can't log output at runtime? Thanks!
