• Windows Forms Error code 2869 with Vista

  We have our application Setup program created using Visual Studio 2005 (Setup & Deployment project). Our application setup program runs fine on Windows XP / 2003, however we get the following error message when we try to run the setup program under Vista: The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2869. According to the Windows Installer documentation, error 2869 means "The dialog [2] has the error style bit set, but is not an error dialog." I don't understand what the issue could be here Do we need to create/build a separate installer for Windows Vista The source of problems ...Show All

• Windows Forms RichTextBox Drag & Drop

  Hi, This is a project which contains a few rich text box controls. Some with drag and drop feature enabled. The problem happens when the application starts, and for only the first drag and drop operation. The drag & drop does not take place and the cursor though changes to the circle with the cross diameter in the target, does not switch to arrow and plus sign in the target box. From the second drag and drop attempt then on, everything works accrodingly. The AllowDrop property is set to true for the intended text boxes, and the code elements commonly recommended for the DragDrop, DragEnter, DragOver, and MouseLeave events are all tried and removed with no success to eliminate the problem. It seems the framework does not require a ...Show All

• .NET Development dll form behaving like an MDI Child form.

  Hi all, Just wondering if there's a quick and easy way of doing this In VB 6, we use API call to made the dll form to behave like a child form of an MDI application. Do any one know of a way to do this in VB .NET I use reflection to call my dll which bring out a form. But this form behave like another separate entity. I want it to behave like a child form to the MDI application i called from. Seems like there's a way to do this in Delphi by passing in Application.Handle to the dll form. Just need some insight. Thanks for reading this far. Dan I had no trouble doing this, but didn't use reflection. Load your Windows Forms project, File + Add, New Project, pick the Windows Control library template.

• Windows Forms Need same event handlers for all controls within a container control.

  Hello, I need ideas how to solve following: I have a UserControl containing several Labels and Panels which provide static information to user. The whole thing shall act as a single component when it comes to handling mouse and/or kbd events, i.e. user input. That means that wherever the user clicks it, the same event handlers or popup menu shall be invoked. If a kind of transparent panel covering the whole UserControl and capturing all input events could be achieved, that would be a solution, however I don't know if that's possible. I don't wish to specify all the same event handlers for each label and panel inside the control as that makes designing less comfy and it's about to forget setting all the handlers properly anyways. Any ideas ...Show All

• Visual C++ Strange Compiler Error!!!!!!!!

  Hello, I have recently begun programming in DirectX. I am compiling a single file(.cpp), that requires nothing but a link to DirectX in Visual Studio 2005 Professional (Which I own). I have linked everything to the DirectX SDK files, but I receive the following errors. error C2065: 'index' : undeclared identifier error C2228: left of '.x' must have class/struct/union error C2228: left of '.y' must have class/struct/union These seem familiar with "C" style errors, but I'm using C++. I might have the compiler settings wrong, so that it could think that it was C, not C++, as .x, and .y is straight C++ so somethign is wrong here, there is nothing wrong with the code, as it is from a book and have given it to other ...Show All

• SQL Server Massive SQL server slowdown.

  Problem: The SQL server slows down immensely, and the OS status shows a HUGE page size usage compared to normal, the processor usage constantly remains between 90-100%. The applications querying the server slows down due to the slow response from the server. This occurs for the same queries, which at some earlier time in the day ran much faster. Some requests also times out. The problem ocurs as the usage time increases - at fist after fresh bootup, the performance is normal.

• Visual Studio Team System TreeDiff question

  Hi All I like the treediff feature. In our company we have been using 'BeyondCompare' to see tree differences. Compare does it well except for the fact I can't export it or even get a print out of it. I was wondering could I export this treediff compare resultset to an excel file somehow or even print out the report somehow   just wondering any hidden option somewhere that I might not be aware of Thanks. That is good enough. But the thing is that it doesn't let me copy and paste in word. print screen won't help coz the number of files changed are more than the screen size. and obviously there isn't any export option. how do u want me to paste it in word ...Show All

• Visual Studio 2008 (Pre-release) Updating custom control

  I am working on an WPF media player control (for various reasons I cannot use MediaControl). I have the video up and running now, but I am in doubt if I am doing the right thing when it comes to updating the control. Currently I am calling InvalidateVisual on the control and then doing the drawing in OnRender, but I seem to remember that invalidate is very expensive. So, how should it be done I would recommend binding the background of a panel to a BitmapSource Dependency property on an object, using the SampleGrabber filter from DirectShow and updating the property within the SampleCallback or the BufferCallback. There is a thread around here on creating a WPF-based webcam application that gives some ...Show All

• Smart Device Development Issue with app Icon on the title bar

    Dear ppl, I have written a windows mobile 5.0 application with 4 forms in it. The first form opens second, the second form opens third and third opens fourth. Each form opens the next form as Modal form. What I need to do is when the Main Form (first form) is loaded, an icon should appear in the Title bar. Now when the user click that icon, the application should hide and vice versa. So if the user is on the 3rd form and when he clicks the icon , all the application forms should hide (fist,second,third), and when the user clicks the icon again, he gets back to the third form and when he close the third form, he gets back to the second form and so on. I have manage to get the icon on the title tray using " Microsoft.Windo ...Show All
