• Windows Forms Vertical Positioning in a RichTextBox

  I have an app (written in C#) with a RichTextBox control. Programmatically, I search for and select a chunk of text with the following code: rtbEdit.SelectionStart = rtbEdit.Find("u#10"); rtbEdit.SelectionLength = intUtteranceTextLength; This works fine except that the selected text is at the bottom edge of the box. I would like the selected text to be in the center of the box, or best of all, allow me to determine where the selected text was positioned before the search, then restore the selected text to the same vertical position. Is there any way to detect and control the vertical position of the selected text   Tha ...Show All

• Visual Basic How should I proceed? Advice, please.

  I'm wanting to use ASP.NET 1.1 and VB.Net to develop a web based control panel for Windows environments. I will be developing on a Windows XP Pro machine but will be debugging on a Windows 2003 machine. My issue though is that I don't know where to begin. My question is where do I begin Some code samples are preferred, if possible, but I'm just looking for a direction to begin. I've done Google searches and MSDN searches for ASP.NET working with IIS but I didn't get much luck in finding anything. Thanks for your help. -Michael One question - why Why reinvent the windows control panel functional ...Show All

• Windows Forms use a variable to cycle through textboxes

  I have about 15 textboxes, all of which I want to save in a string array. Right now I just code: array[0] = txtbx1.text array[1] = txtbx2.text.... and so on. Is there a way that I can use a for loop and use x  instead of 1 and 2. so it would look like this:   For( x=0;x<=15;x++) { array[x]=txtbx + x.text; } instead of writing it 15 times Thanks.

• Windows Forms How can make the column completely viewable in a datagrid?

  I am using VS2003 version, and a datagrid in it. This datagrid is dynamically populated with a dataset and the columns and the actual width of the data are unknown. Now, when I populate it, it comes with fixed column width. If I double click on the right corner of each column, it expends the width to show the text completely, just like excel spread sheet. Is there any standard feature to say - extend the column width to the max value of data, basically to automatically do the double click over each column (other than custom datagridstyle) Thanks, ...Show All

• Visual Studio Team System Custom rule for investigating a switch statement

  Hello I've been playing with custom rules for the last couple of weeks. In one of my rules, I'd like to investigate switch statement for the existance of a default case. I wish to obtain a list of cases within a switch statement. I investigate instruction lists of a method, but all I can find are elements with a 'switch' OpCode. Do you guys know how can I do it Any suggestions are welcome. Regards, Luke This is not possible, unfortunately, as FxCop is strictly a binary checker and many details of a switch{} construct are hard or impossible to recover from emitted IL.

• Visual Studio Express Editions How to burn MSVS 2005 Express CDs

  Hello everyone,   Due to the stupid .img format that the Offline installers are being distributed in I have decided to write up how to convert it into a .bin file which is more widely supported. My copy of Nero 6 was unable to load or recognize the .img file, and the extraction instructions on the offline installer instruction page produced a copy of VSC++ that was not installable.   Okay, load up the image in ISOBuster, right click on the " CD " and select " Extract CD <Image> " then " RAW (*.bin, *.iso) ". Save the file as " IMAGE.BIN " and wait for the extraction process to complete (takes 5 mins). ...Show All
