• VDeepak Menu Strip Colour Issue

  I was messing around with the colour of my form's menu strip... Later I decided to not do that... When I tried to change it back to SystemColors.Control it just stayed that color, It didn't go back to the Blue Windows XP theme's colour... I fixed the problem by deleting the code in the designer... The Menu Strip went blue again and I was happy... Still though, This is a bug that *should* be fixed... Did you try deleting the background color Basically, you have set the color to the 'control' color. Prior to that, even though it shows 'control' it's not actually the control color (notice the color is in bold - it's not the default). I wouldn't call it a bug, per se. Just a bit of unusual presentation behavior (since by def ...Show All

• Kitsok Deleted row of a Datagridview

  Hello. A question please. When the user deletes a row of a datagridview, I recognize the event with RowsRemoved. But how can i recover a value of that deleted row in the rowsremoved event Thanks...

• John Dekker converting entire array without loop?

  Hi all, can I convert an entire array to other datatype in one statement preparation: dim test(100) as int16 for i=0 to 100 test(i)=i next i and later on: for i=0 to 100 test(i)=cbyte(test(i)) next i Q: can I do that somehow in one statement (with the purpose of being faster; the example is a simplification) Thanks, Kees Hi Kesim, It depends on the datypes involves. There are lots and conversions like unicode to byte in the system.text.ecoding and there is Bitconverter. A great component of the VS2005 is the object broswer which will let you search all classes methods, functions and objects for a string match, the string being your choice. Renee ...Show All

• a.E Limits on Memory Use?

  Hi all, I was testing the VB2005 Express and decided to create a large array in the IDE. My 32bit XP Pro machine has 3.5GB available and I thought I'd check to see how much I could use with VB.

• Adhvika Error Message that I can't resolve...

  I am fairly new to writing in VB and in reality it is actually my first true language that I am trying to learn. I am currently writing a small application for where I work that will be used internally by only a couple of people. The purpose of this project is to record and maintain records for troubleshooting calls. This is in essence a CYA (cover your *ss) ploy that also helps us maintain with compliance rules. So essentially what I did was create a small program that would refernce back to a database out on one of our servers. This was supposed to be something that I assumed would be very easy, and at first it did seem to be working properly. Now I have run into a problem that I do not have a solution for. The following is the error I g ...Show All

• Worf Is it Recursion (or is it Memorex)

  I have a function called from a paint event that writes (DrawImage) on the control. It works ... so I thought nothing more about it ... U N T I L ... I went back a put a breakpoint into the code to Debug a problem, and then I noticed something strange. Instead of just working and exiting, it keep re-entering the function. I put a counter in it and it re-entered at least 14 time. I image it has to do with the 'Paint" event, but it certainly worried me. Here is the really strange part: When I took the breakpoint out, the counter now says the function is only entered once.

• fortellinator Process not completing

  I have a vb form that runs a command line executable that creates a diff file from two existing files. When I run the program from the command line it creates a 419Mb diff file. When I run it as a process from my VB program it gets to ~400 Mb and stops. If I kill the VB program the command line executable continues to run and finishes the diff file. So I have 2 questions. Why does the process stop before for it finishes when I run it inside vb Why does the program continue to run when I kill the VB app. Here is my code Private Sub xdelta( ByVal strFile1, ByVal strFile2, ByVal strDelta) Dim strError As String Dim p As New Process Dim info As New ProcessStartInfo info.UseShellExecute = False ...Show All

• Tin Aung Soe Optimizing Search

  I am using VB.NET 2003 and MS Access. I have a TextBox and below it is a ListView control. As the user types a character in the TextBox, the records starting with that character get filled in the ListView control. The records are fetched from either Oracle or Access database. Previously, I used to execute a SQL query, which looked something like this: "Select FirstName from TableName where FirstName like '" & TextBox.Text & "'%" This query was set to execute as the text in the TextBox changed. If the TextBox is blank, then all the records get displayed on the ListView alphabetically. Now I have decided to use a different approach so as not to query the database again and again. Now what we are doing is that ...Show All
