Visual C++ Datasets, datarows oh my
Good evening experts: Would you happen to have any online reference material, perhaps an article or coding sample, that provides the general idea of working with datasets in vc++ 2005 I've found numerous examples with 2003, but it appears that the syntax has changed so those examples are working. I like New DataSet Features in Visual Studio 2005 ; but, there's also TableAdapters in Visual Studio 2005 , and Visual Studio 2005: 101 Samples for Visual Studio 2005 includes a Data Access Samples section. ...Show All

Visual Basic It's slow!!!
Hello After I turn on my computer and when I launch first program (which programed by VB2005), it's take a long time to show main form. VB6 was faster. CPU speed: 2600 MHz Memory: 1024 MB Is there a solution for that Thanks & Regards What do you mean by 'long time' It's possible that, even though windows appears to have finished booting up, it hasn't - it's still loading and starting various services (e.g.SQLServer). Additionally, it may be that the .NET framework needs to load prior to your application loading. Did you try using a splash screen to see if t ...Show All
Visual Basic SHAddToRecentDocs problem
I used SHAddToRecentDocs(2, installpath & myfile) to add myfile to Recent documents. Then I used the following loop to Wait for the SHAddToRecentDocs to add shortcut Do While Dir(RecentPath & myfile & ".lnk") = "" Loop The problem is that it never gets out of the loop. Could anybody help me to point out why I checked the Recent path to be correct and also checked that the 'myfile' is in the Recent folder.

Game Technologies: DirectX, XNA, XACT, etc. Scaling (Shrinking) Sprite Chops Off Texture...
I am using the October 2005 Release of DirectX 9.0. When attempting to Scale a Sprite I am running into some very odd behavior. When "growing" the Sprite the Texture stretches and maps fine. When "Shrinking" the Sprite the texture apparently does not shrink - and it gets cut off. I am setting the Transform properly on the Sprite, applying SpriteFlags.AlphaBlend to Sprite.Begin(), and using Sprite.Draw(). Is anyone else having this problem Funny you should mention it. I was going to post a thread about the very same thing today. I set up a test case in Direc ...Show All
Windows Forms DataGridView and posting changes to DataTable
This problem appeared many times on this forum but in my case none of the solutions worked. The story is that changes do not appear in DataTable. dgv is bound to a dataset and DataMember has been assigned to a DataRelation (by its name). It views data fine, but when I type anything in dgv I can't see changes. I'm handling events TableNewRow and ColumnChanged. Those events are raised as they should when I change/add rows on dgv. When I don't press an arrow to go to the next datagridviewrow changes are not in the datatable. Before posting changes to database I'm trying to force saving data to datatable by tricks like dgv.Invalid ...Show All

Visual C# Dynamically moving controls
I have six panels, each panel contains a textbox and its label. Each panel has a checkbox associated with it on the form, but outside of its respective panel. I only want the panels whos checkboxes are checked to be visible. If another checkbox is checked, I want that respective panel to be displayed directly under the last panel displayed. Once that checkbox is unchecked, I want the panel to disapear, and all the other panels that come after, to move up. I am going crazy trying to get the code right, and I thought maybe someone has already done this as could give me an idea on how to get all these panels to apear and dissapear, and repositi ...Show All
