• Windows Forms Cannot Read .Text Property of TextBox

  I am simply trying to read the .text property of a TextBox in VS2005 but, even though I know there is text in there, no text is detected. I'm wondering if it has anything to do with the textbox being on a tabContainer in a SplitContainer. The textboxes are bound to data and the data displays on the form. My code recognized that the textBox is there but does not read the text: foreach (TabPage tp in tabControl_ProcA.TabPages) { tabControl_ProcA.SelectedTab = tp; if (tp.Name == "tabPage1_Cabinets" || tp.Name == "tabPage2_CylPipes" || tp.Name == "tabPage3_AngleIrons" || tp.Name == "tabPage4_Beams") { foreach (Control ctl in tp.Controls) { ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Packaging assets

  I haven't got into using XNA as of yet, however I very much like the idea to play my games on the Xbox360 (blah blah blah). I see that the XNA team has put large amounts of effort into some asset management in XNA, that includes the XACT audio cues for like "make it possible to change the sound triggered by some event without doing it in the programming". I'm fairly deep into the process of making my customized packaging format with the goal to essentially archive anything (textures, sounds etc) into a single or more packages. There are several reasons, one of them because I started before the XNA project was convened, and to ease distributions on levels and mods by packing several files, textures, sounds, scripts in a single package file. ...Show All

• Visual Studio 2008 (Pre-release) Help: RC1 ListView Memory Leak

  I've got a memory leak problem with the ListView. I just have a long list of items that I put in a list with 2 GridViewColumns, and as I scroll up and down the list the memory goes up and up and up, until I eventually run out of memory on my machine if I do it long enough. I find it hard to believe that there's a problem like this with list view, so I'm wondering what I've done wrong. I'm running RC1 on Windows XP x64. I've done a real simple example. The code is below. You can run an XBAP version from here: http://150.101.100.238/~john/LeakyList/LeakyListXBAP.xbap In task manager, watch PresentationHost.exe Mem Usage grow as you scroll the scrollbar up and down. Press "Collect Garbage" and the Mem Usage won't go down ...Show All

• Visual Studio Express Editions Odd behaviour with ErrorProvider

  Hi, I'm using VS2005. I have an ErrorPRovider for a masked textbox and also am using an 'Enter' event (to select all text in the masked textbox when you enter it.) The odd behaviour is that the ErrorProvider icon doesn't show unless you hit tab twice; the caret doesn't leave the textbox with the first 'hit' of tab, but doesn't show the ErrorProvider until the second hit. I traced the code and what's happening is that the first hit of 'tab' causes the 'Enter' event to fire; this delays the showing of the ErrorProvider icon. This seems strange since my understanding is that setting e.Cancel to 'true' prevents the user from leaving the textbox until the problem causing the error is fixed. Why, then, is there a re-enter going on ...Show All

• Windows Forms Windows.Form.DataGrid And Large Sets Of Data

  Hi there, I guess this is a FAQ-type of question, and I actually seen it asked for a number of times on these forums but nobody was able to answer it so I am giving it another try... I am having a large data set (in a broad sense), and would like to browse it using the mentioned above datagrid. I've implemented IList for my data (which resides in a simple binary file), and trying to use the grid with my implementation of IList. THE PROBLEM: DataGrid is sucking all the data into memory, and the app eventually runs out of memory. (I put a breakpoint in my item[] implementation and yes, it is called as many times as there are items in my list, actually a little more). This is not acceptable for 2 reasons: program runs out of memory, and if ...Show All

• Internet Explorer Development Default disabling of "Navigate sub-frames across different domains" breaks many sites

  The default disabling of "Navigate sub-frames across different domains" setting is causing numerous web sites to stop functioning. This issue has been discussed most lately at "IE 7 and Frames" by raghava66 on Oct 19, 2006, but the problem was actually reported as early as RC1. Since it is a long established browser default setting, many frameset-based public and intranet sites have grown to rely on the ability for one subframe to navigate the URL of another subframe, e.g. in a tree/list view - reading pane layout. Asking end users to manually change their default security options here is not a viable option. In addition, many new AJAX applications are built to rely on cross-frame cross-domain messaging (not scrip ...Show All
