• Windows Forms passing variables to form

  I made my textboxes on form1 public. I was able to access them through my form2, after I made a statement like form1 form2 = new form1();   Problem is, the text boxes are all empty on form2. Is this because I initiated a new form1 and therefore the textboxes are set back to their default as empty How can I access variables stored in form1 from form2 thanks. Awesome.. thanks.. that worked.. I have no idea why I never tried that. So all I gotta do is define my variables globally. I thought I tried that.. guess not cause I tried a few tests and it works great. Jeez this language makes it awkward to p ...Show All

• Visual C++ std::map<,>, xtree and find

  I am working on an unmannaged C++ application in Visual Studio 2003.  The application is using STL map class. std::map<ApxString, CGPO> GPOs; GPODataFactory.GetGPOs( pContext,  GPOs); std::map<ApxString, CGPO>::iterator GPODataIter = GPOs.find( GPOGroupKey)   GPOGroupKey is of type ApxString of course and it was initialized to "T" earlier in the program. When I go through the debbuger in the GetGPOs function and use the find function, I find the row I am looking for.  However, when I go through the find function after I exit the GetGPOs function, I don't find it. As I stepped into the find function, ...Show All

• Visual Studio Team System Visual Studio "disappears" during large checkin

  This morning I added 22515 files to the TFS Version Control which worked smoothly and very quickly. However, when I flipped to the pending changes window and attempted to commit the added files, Visual Studio cleanly terminated itself after about 15-20 seconds. I saw the TFS communication dialog popup it did some animation and then the whole of VS was gone. Restarting Visual Studio and performing the operation again completed successfully. Let me know if there is any more information that could be of use in tracking this down. Hi Buck, This was the RC. Unfortunately it was a clean kill so there was little to go on. I tend t ...Show All

• Visual Basic Not number.. but why?

  Hello! I have a big problem. A wrote a little program: Public Class Form1 Private Sub Button1_Click( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim a, b, c As Single a = TextBox1.Text b = TextBox2.Text c = TextBox3.Text Label1.Text = -b + Math.Sqrt(b * b - 4 * a * c) End Sub End Class But it display the "not number" text in label1...

Try for instance to add this line of code Label1 ...Show All

• Windows Forms What is the best practice to store application messages in multi-language applications?

  Hi, I'm developing a multi-language application. For localization within buttons, labels, and everything on forms, it's quite simple as you all know that the VS.NET manages satellite assembly for us. However, what about other messages such as application messages which are shown in MessageBox and error messages As far as I can imagine, there are 3 ways :- 1. Store these messages in database by making a table like (messageID, cultureName, messageText). But I feel it seems like stupid as I add up more maintenance task for maintaining multi-language data in the database. Anyway, is this a good approach or it is good for any scenari ...Show All

• .NET Development txt File partition

  Hi, I need to read a .txt file , partition it into smaller .txt files ,and then saving them. The partition process depends on finding the carriage return (enter) character. How can I doing that Thanks in advance , Aya. You might want to be careful doing the way that Kevin suggested as this will cause problems when reading large text files. His solution will read the entire text file into memory and then make another copy of it. So if the text file you reading is 10 MB, you application will consume 20 MB memory when calling this method. It might be better to read a line in at a time: ...Show All
