• winforms - gridview cell timespan edit problem

  - by Sharique

  I'm following this question for formatting timespan value in the gridview. Format TimeSpan in DataGridView column I'm diaplying only minutes value in grid as follows DataGridViewColumn idleTimeColumn = myGridView.Columns["IdleTime"]; idleTimeColumn.DefaultCellStyle.FormatProvider = new TimeSpanFormatter(); idleTimeColumn.DefaultCellStyle.Format = "m"; This cell is editable, so when I enter 5 (that mean 5 min) in the cell, then it should take it minute, but it take it as day value (ie, 5.00:00:00). I tried different values for format (mm,%m) but all these gives the same output.

• Why Does Thread.CurrentThread.CurrentCulture Change between Page Rendering and HttpModule.PostReques

  - by Chad

  I'm creating an HttpModule that needs to know the value of Thread.CurrentThread.CurrentCulture as set in an MVC application. That value is currently being set by the BaseController, but when my HttpModule.PostRequestHandlerExecute() method fires, it reverts to what the Culture was prior to page rendering. I have duplicated this by creating a simple web app with these steps: Module.PreRequestHandlerExecute: Set culture to A Page_Load: Culture is currently A. Set culture to B Module.PostRequestHandlerExecute: Current thread culture is A. I expected it to be B but it was changed between page rendering and PostRequestHandlerExecute Any idea why .Net changes this value or how I could get around it? The thread is the same, so something in .Net must be explicitly reverting the culture.

• Using Bookmarklet to open and pass values from Parent and Child Window

  - by kunalsawlani

  Hi, Is there a way to open a window from the current page using a javascript bookmarklet, and once the the child window has finished loading, setting the value of one of the elements in its DOM to some value from the current page, say for example the currently selected text. I know that this can be done in plane javascript, and also, by appending the value to the URL, and reading it from the web service opened in the new child window. I want to know if there is any other way, as the appending URL method does not let you send text more than two thousand odd characters long. Appreciate any help I can get!

• A very weired problem with texbox control in C# .net

  - by Kazoom

  Well i know textbox is a very simple user control, perhaps the first input control ever made. I have been facing a very frustrating problem with this simple control. I programatically add a textbox in my user control. From ui i am able to edit it like a normal textbox. however, i am not able to read the user inputed value in the program. my program all the time sees the old value with which my text box was initialized. i textchange event getting triggered but the value never gets updated. This seemingly looks to be some innocuous bug in the code, but the program is very simple and it does not seem to be having any bug. Any guidelines on this issue?

• Using string[] as a Dictionary key e.g. Dictionary<string[], StringBuilder>

  - by Nick Allen - Tungle139

  The structure I am trying to achieve is a composite Dictionary key which is item name and item displayname and the Dictionary value being the combination of n strings So I came up with var pages = new Dictionary<string[], StringBuilder>() { { new string[] { "food-and-drink", "Food & Drink" }, new StringBuilder() }, { new string[] { "activities-and-entertainment", "Activities & Entertainment" }, new StringBuilder() } }; foreach (var obj in my collection) { switch (obj.Page) { case "Food": case "Drink": pages["KEY"].Append("obj.PageValue"); break; ... } } The part I am having trouble with is accessing the Dictionary Key pages["KEY"] How do I target the Dictionary Key whose value at [0] == some value? Hope that makes sense

• nmake.exe: is there a way to exclude a file from a set of files specified in a macro?

  - by Cheeso

  I'm looking for something like the Exclude filter for msbuild, but I Want it in a makefile processed by nmake. Is that possible? Suppose I have a makefile that defines this macro: SOURCES=xxx.c yyy.c zzz.c and I invoke it with nmake OLD=xxx.c NEW=bbb.c ...can I produce, within the makefile, a macro with a value like: yyy.c zzz.c bbb.c ...basically substituting bbb.c for xxx.c ? The files can appear in any order. This would be pretty easy if the string substitution that is possible in nmake macros, allowed for evaluation of macros. In other words, I can do sources=xxx.c yyy.c zzz.c objs=$(sources:.c=.o) and the value of $(objs) is xxx.o yyy.o zzz.o But nmake does not allow a macro for the value of either argument to that substitution. I cannot do this: new=.o sources=xxx.c yyy.c zzz.c objs=$(sources:.c=$(new))

• In Zabbix how to zero data when it doesn't comes?

  - by Jader Dias

  If a variable is expected to be fetched every minute, and it doesn't happen, the graph shows the last known value for all the timespan until the next known value. The expected behavior for me is that the graph showed no line, or a line next to the zero, where there is no data. How to achieve this with Zabbix?

• Ajax method within a added method in jQuery validator

  - by nikospkrk

  Hi, I'm kind of stuck with this pretty simple (I'm sure) jQuery/Javascript issue. Here's the code : jQuery.validator.addMethod("emailExists", function(value, element, param) { var email = value || ''; var valid = 0; $.ajax({ type: "POST", url: param, data: "email=" + email, success: function(msg) { if (msg != '' && msg) { valid = 0; } else { valid = 1; } } }); return valid; }, "* Email address already registered, please login."); This function is called where a user type his email address in a registration form, and everything seems to work perfectly, except that my valid variable returned isn't updated, whereas when I use an alert box it is properly done! It looks like it return the value before the AJAX is done, any idea? Cheers, Nicolas.

• PHP: How to use mysql fulltext search and handle fulltext search result

  - by garcon1986

  Hello, I have tried to use mysql fulltext search in my intranet. I wanted to use it to search in multiple tables, and get the independant results depending on tables in the result page. This is what i did for searching. $query = " SELECT * FROM testtable t1, testtable2 t2, testtable3 t3 WHERE match(t1.firstName, t1.lastName, t1.details) against(' ".$value."') or match(t2.others, t2.information, t2.details) against(' ".$value."') or match(t3.other, t2.info, t2.details) against(' ".$value."') "; $result = mysql_query($query)or die('query error'.mysql_error()); while($row = mysql_fetch_assoc($result)){ echo $row['firstName']; echo $row['lastName']; echo $row['details'].'<br />'; } Do you have any ideas about optimizing the query and format the output of search results?

• Hiding Table Rows

  - by David Stein

  I have a table that I'm using to show details from the line items of a quote. I want to hide a particular row depending on the value of the field in it. The expression I've tried is to set the row visibility to: =IIF(isnothing(First(Fields!NEW_PRICEBREAKS.Value, "QuoteDetail")),true,false) When I run the query from the dataset "Null" returns for NEW_PRICEBREAKS for most of the records. Also, when I expanded the row with another column with this expression: =IIF(isnothing(First(Fields!NEW_PRICEBREAKS.Value, "QuoteDetail")),"is nothing","not nothing") I see "not nothing" repeated over and over again. I've attempted to use TRIM inside of the isnothing to remove spaces and it still doesn't work. Also, the sql data type for NEW_PRICEBREAKS is nvarchar(MAX). Any ideas how I can suppress this row correctly?

• How to make a UserControl with a custom DefaultBackColor?

  - by Blorgbeard

  When I right-click on my custom UserControl's BackColor property in the property-grid, then click Reset, I would like the BackColor property to change to (for example) Color.LightGreen, and the property value to appear un-bolded, to indicate that it is the default value. Currently, I know I can do this: public override void ResetBackColor() { BackColor = Color.LightGreen; } Which works as far as setting it to LightGreen on reset. But it still appears bolded in the property-grid, indicating that the current value is not the default. I notice that the Control class has a static read-only property, DefaultBackColor. Unfortunately, since it's static, I cannot override it. Is there some way to get all the functionality I want?

• Ajax.BeginForm is submitting disabled form elements

  - by Fiffe

  Using MVC3 and Ajax.BeginForm I surprisingly discovered that mvc ajax forms submits elements with the attribute disabled="disabled". I have tested both select and text inputs. I was suprised because they should not be submited and they will not when using Html.BeginForm. Is there some hidden option or a workaround for this? [EDIT example] @using (Ajax.BeginForm("Action", "Control", new AjaxOptions() { HttpMethod = "POST" })) { <input type="text" name="_enabled" value="_enabled" /> <input type="text" name="_disabled" value="_disabled" disabled="disabled" /> <input type="submit" value="POST" /> }

• Oracle Apex:Why is this dynamic action not getting triggered/fired ?

  - by Sathya

  I'm using Application Express 4.0.0.00.25 ( Apex 4.0 EA2 ). I've created a tabular form, with few fields. Each of the field are not direct entry, but rather a LOV picker is attached to these, and on selecting the LOV value, the id gets stored in the field. I have a dynamic action associated to the field, ( event - change in item, condition - always, action - Set value via SQL query ). However, on selecting the value from the LOV, the dynamic action doesn't get triggered. If I select the dynamic action to be fired on page load, then it works but not upon selection of an item from the LOV. Why is this so, is it by design or a bug ?

• jQuery - change a list of elements to an associative array

  - by Brian M. Hunt

  Given an associative array (of the sort returned by jQuery.serializeArray()) like this: [ { 'name': 'abc', 'value': 'aaa', '__proto__': [Object] }, { 'name': 'def', 'value': 'bbb', '__proto__': [Object] }, { 'name': 'abc', 'value': 'ccc', '__proto__': [Object] } ] How can one convert this, using either jQuery or just javascript, to an associative array of name: [values] like this: { 'abc': ['aaa', 'ccc'], 'def': ['bbb'] } This seems to essentially be the inverse of this question: Build associative array based on values of another associative array... but in Javascript (not PHP). I wasn't able to find this question on Stackoverflow, though I thought it would have been asked. Thank you for reading. Brian

• When should I use String.Format or String.Concat instead of the concatenation operator?

  - by Kramii

  In C# it is possible to concatenate strings in several different ways: Using the concatenation operator: var newString = "The answer is '" + value + "'."; Using String.Format: var newString = String.Format("The answer is '{0}'.", value); Using String.Concat: var newString = String.Concat("The answer is '", value, "'."); What are the advantages / disadvantages of each of these methods? When should I prefer one over the others? The question arises because of a debate between developers. One never uses String.Format for concatenation - he argues that this is for formatting strings, not for concatenation, and that is is always unreadable because the items in the string are expressed in the wrong order. The other frequently uses String.Format for concatenation, because he thinks it makes the code easier to read, especially where there are several sets of quotes involved. Both these developers also use the concatenation operator and String.Builder, too.
