I have a DataGridView with one column, I set for that column
DefaultcelStyle->Wrapmode=True
Modify data a with a long string, I call also
vb.net
DataGridView1.AutoResizeRows()
DataGridView1.Refresh()
But the DataGridView doesn't refresh wrap,il looks like this : I change manually current selected row moving to another record and now the refresh is done :
Is there any way to wrap text in the DataGridView control? When I do it doesn't auto resize the row height so it becomes mostly hidden.

Quick query...I'm trying to scan a long string and return any values that occur between the tags <FileName> and </FileName> I've got a bit of code here to use regular expressions to return the position of the occurunces of both substrings..Just wanted to find out if there is any way to scan for both substrings within one loop (as im currently doing 2, one for the first substring and one for the 2nd) so I can use something along these lines:
ringlist = Mid(XMLRESP, (startloc + 1), (endloc - 1))
MsgBox(ringlist)
to msg box the value between the substrings...either that or another approach to return the value between the 2 substrings (it can be of variable length)

View 1 RepliesI've done some VB Script and I know C++ fairly intricately. I'm having trouble understanding, and making for loops with if statements perform as expected. What I'm trying to do is iterate through a string and turn all of the "a"s into "c"s "b"s into "d"s and "c"s into "e"s? Here's what I've got thus far and I'm keeping the old string intact.
For i = 0 To first_string.Length - 1
If first_string(i) = "a" Then
second_string = first_string.Replace("a", "c")

I can do this for loop in my sleep in C++, but it seems that the increment counter i is never what I expect it to be. It should start as 0 (first letter of string) replace whichever of the three it finds, then change to 1 (second letter of the string) and replace whatever it finds there right?

I have a very long string. I need to parse this string so I can get information out of it. I know what each segment starts with and ends with. The length of the information will vary. I don't know what the easiest way of parsing this string.
