• Visual Basic Scrolling Treeviews and DataGridView together

  I have Treeviews and DataGridView side by side, and I would like to scroll these controls together. So if the user scrolls down one Treeviews or DataGridView, the other would scroll automatically. How should I do this in VB .NET 2005 I would keep the index of the first displayed row/node the same (or whatever index matches) in both controls. I don't know the DataGridView control too well, but I think it's these: TreeView.TopNode.Index DataGridView.FirstDisplayedScrollingRowIndex ...Show All

• .NET Development Problems with reading from an INI file

  I'm reading from an INI file using the Win32 method GetPrivateProfileString, but it seems to be too slow. How do I correct it or rather, how else can i read from an INI file in a faster, more effecient way . Thanks in advance I did some profiling on GetPrivateProfileString(), digging a 79 character string out of the bottom of a 7500 byte INI file. I got 0.101 to 0.209 msec per call. Testing it on a small INI file with the key near the top didn't improve the speed much: 0.078 to 0.141 msec per call. I repeated the exact same test on a VB6 program and got the exact same timing. So it is not P/Invoke that is slowing things down, it is just that GetPrivateProfileString() is slow. Not surprising, considering w ...Show All

• Visual Studio 2008 (Pre-release) WPF Memory Usage

  Just wondering.... Is a compiled MSbuild WPF app supposed to be 20mb resident. - I find this tobe ridiculously huge considering all I have on the screen is a window and a button - without any styling. I understand that my exe is only 50Kb -probably cause it's only a script. I mean I added a couple of extra controls and something with a Tab interface with two pages loaded rises upto 50Mb resident. If I could pose to any-one that could inform me of a way of removing the clutter - could I perhaps limit the necessary object instanced to save on runtime memory. ,eg. use onover images as butons instead of the SVG buttons. -I understand that this is not what WPF is supposed to be all about, but If I am to make an app that runs on existing hardwar ...Show All

• Internet Explorer Development IE 7 Tab windows - how to get handles to them?

  Hi , I am programming an extension for IE. This works fine with IE 6 or previous but I need the handle to active window in IE 7. If Tabbed browsing is enabled then it creates problems as I have handle to whole window and not to an active document. I want to print only current tab. My question is , 1. How do I sense which tab is currently active ( I am sure MICROSOFT developers handle this as you can see the window title and address bar changed everytime you change the tab but there is no direct programming interface to it. ) 2. When I print the document to convert it to PDF, it prints all tabs. I don't want to print all tabs. i use visual basic and iewebbrowser.execwb method to print. Any help will be appriciated. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Individual mesh material transparency and reflection

  I have a room, which is a mesh; it is made up of approx 100 materials. A few of these materials are glass windows. I would like to make materials which use a specific texture (glass) to be transparent (and, if possible, reflective). Any ideas on how to get started This is my render method which is called in the Direct3D render loop: public void Render() { for ( int i = 0; i < content.LobbySceneMaterials.Length; i++) { ExtendedMaterial material = content.LobbySceneMaterials ; string key = material.TextureFilename; if (! String .IsNullOrEmpty(key)) { // Set texture from content where filename matches. Texture texture = content.LobbySceneTextures[key]; device.SetTexture(0, texture); ...Show All

• Visual Studio MPF GetFileNamespace method contains a bug

  Hi there, In MPF file <VSSDK>\2006.09\VisualStudioIntegration\Common\Source\CSharp\Project\TokenProcessor.cs there is a line of code (313) : string projectPath = Path .GetDirectoryName(node.ProjectFile); This line returns an empty string. I think there shoud be a following line instead: string projectPath = node.ProjectFolder; From my point of view that is a bug. Isn't it Hello Dimitry, It is absolutely correct that TokenProcessor class contains bugs.  Thank you for reporting your observations. We will address these bugs in the next ctp of the vssdk. Also notice that the tokenlist is not reset when new files are added. This bug causes the class name of the newly inserted files to be wrong. ...Show All

• .NET Development How to make global data thread safe ? Please Help...

  Hi friends, I seem to be stuck in a peculiar problem. I have a public static class with public static members (different array lists). The members are thus global in nature and accessible across the namespace. I have a worker function which is called asynchronously (so that there are several instances running per second) and which reads the different global members at different points of execution (not the entire set at any one point). I have a writer function which is used to set the global members and this is the only one in the application writing to these variables. It will write the entire set of globals when given control through a GUI event. I need a mechanism where if one instance of worker function is accessing any ...Show All

• Windows Forms foreach(Form f in AllformsOfApplication)

  Hi, searched the forum, found something that wouldn't work, so I'm asking for some help. I'd like to find all forms in my application after clicking on a menu item, so I can do something with all of them. That would be something like: foreach (Form f in AllformsOfApplication) { dosomething(f); } Note: not just the open forms like with Application.OpenForms but something like Application.AllForms (if only it would exist...) Thanks for the help! I'll try to be brief... I'm starting from an Open Source project which has a mechanism for translations built in. It's kind of complicated so I'm not going to explain that, but I know how it works. One of the things it does is write all of the contents of the Text ...Show All
