• Visual Studio Express Editions Form 1, 2,....

  How can I make from Form1 to Form2 on buttom click WITHOUT NEW WINDOWS I want all form in only one form. Please help thank you so much! I dont think you can do this, when its a new form its a new form. You can hide your form and then show the other form but in order to show back your main form, you need to have a reference of it to the other form so it can set it to visibility   you could probably use MDI for this: http://vb-helper.com/howto_net_mdi.html http://abstractvb.com/code.asp A=957 https://msdn.microsoft.com/library/default.asp url=/library/en-us/vbcon/html/vbconMDIApplications.asp ...Show All

• Visual C++ C# DataGridView control in CWinFormsControl hangs on ALT + TAB

  I am developing a DataGridView control in Virtual Mode on a UserControl using the code in this article http://msdn2.microsoft.com/en-us/library/15a31akc.aspx Then it is hosted in an MFC dialog using the code in this article http://msdn2.microsoft.com/en-us/library/94t3ebxz(VS.80).aspx So far so good and everything works pretty much as it should. However if you ALT + TAB off to another application halfway through editing a cell the application hangs e.g. if you type 4 and then ALT + TAB. If you ALT + TAB to another application at any other stage there is no problem e.g. if you type 4 then click on another area of the UserControl and then ALT + TAB.

• Visual C# Differences between i++ and ++i

  Hi to all! Sorry for my ignorance but could anybody explain me what is the difference in a cycle when we increment a variable i in this way i++ and i++ e.g. for ( int i = 0; i < 10; ++i ) and for ( int i = 0; i < 10; i++) Thanks a lot in advance! i++ is using postincrement. It means that the number is incremented after it's use. For example: int i = 5; foo(i++); // 5 will be sent into foo as a parameter, and i will then increase to 6. Preincrement on the other hand increments the value before using it. For example: int i = 5; foo(++i); // 6 will be sent into foo as a parameter. Did that answer your question ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Render target save'n'restore

  I've a func that do some work including rendering into rt. So, i need to save old rt at the beginning of my rendering, and then restore it at the end ( when smb call my func, he may have rendering to texture enabled, or just rendering to the backbuffer, and he don't wont to worry about restoring his rt after call of my func ). Is there any way to implement such a behaviour using XNA The PC version of XNA uses the same code path.

• Windows Forms Text Color problem

  Hey, Below is the code I did to make the text color change, it does not give me any errors but it wont change the color of the text when I test it...here is the code: private void textColorToolStripMenuItem_Click( object sender, EventArgs e) { RichTextBox thisrichtextbox = GetCurrentTextBox(); colorDialog1.Color = thisrichtextbox.ForeColor; colorDialog1.AnyColor = true ; if (colorDialog1.ShowDialog() != DialogResult .Cancel) { colorDialog1.Color = thisrichtextbox.ForeColor; thisrichtextbox.SelectionColor = colorDialog1.Color; } } Thanks :) I believe that's because your ColorDialog1's Color is set (again) after dialog is closed. In the end,  ...Show All

• SQL Server Question about by Import oracle data and field is null

When i look in preview query result, via OLE db Source editor > Preview, this field contains '<value too big to display>'. What do i do wrong Can somebody help me Thanks in advance Olaf Olaf - SQL Server has several methods to export and import data, as does Oracle. For most data cleansing issues, the simplest way to eliminate data format differences is to export the data from Oracle to a text file and then import that to SQL Server. If you're looking for something that is simpler, such as using SQL Server Integration Services ( ...Show All

• Visual C++ DLLs unloaded

  Hi, guys: I have a COM component. It uses several third party DLLs. Recently, I noticed that after the DLL holds the COM component is unloaded from the memory, the third party DLLs can stay in the memory, and when recreating the instance of the COM component, the third party DLLs will not be reloaded. Sometimes, this will cause GPF. My question is why the third party DLLs can stay in the memory, and how can I unload them Thanks, Zhen It looks like the third party DLLs are not COM components. They are implicitly linked to my COM component. I am pretty sure the COM component is the only one references them. My codes do not call LoadLibrar() as they are linked implicitly.
