Hi
I tried more. now that I destroy the Icons, an Overflow error occurs when the number gets more than (about 1800) on the ImageList1.Add ... line.
I was interested to see if this problem happens for all applications using an imagelist to lead to an overflow. So i used a windows search with * criteria to check that when there is large number of files in a listview (which is for the case of windows search) and the fact that icons in a listview should be in an imagelist, to see if the oveflow occurs. But it didn't!
I checked my code so many times. I don't think I have missed anything else.
Is it the end and I cannot do anything with the overflow problem?

WHOA! Stop right there! This is not a fact! This is an assumption. You're assuming that the images are kept in am Imagelist. I personally hate the ImageList control and avoid using it whenever possible. If I were to keep that many images, I'd write my own class and ownerdraw each line of a ListView to show them.

Oh! I guess I have to write my own class! 
But if you'd read my other note here, I checked the ImageList, really why it can't hold that much of items?
Or you want to insist that Listviews used in windows ARE all ownerdrawn?

I finally used the following code to see if the problem is really with the ImageList control or not:
<br />
Do<br />
ImageList1.ListImages.Add , , LoadPicture("f:\1.ICO")<br />
i = i + 1<br />
Loop<br />
And it raised an overflow error when adding i=2800
WHY is so?
I checked that windows, can have a listview containing more than 5000 items (each icon should exist in an imagelist, shouldn't it?).
So if that is possible, what about my app?

Hi, I am investigating on how Visual Basic 6 could fully support Farsi Characters. I have heard that there are some characters which are not supported. Although I dont know which ones they are. Could anyone help me?

If your OS supports Fasi language, it hase no problem with that. I had used vb6 to write a Farsi Language program. It worked under windows XP quite well and also under windows 98 with right-to-left and Farsi language support.
But you may have a little problem when dealing with some controls that do not support right-to-left.

Hi. Thanks for the response. MOst of the controls I'm using supports Arabic Right-To-Left. However, I am wondering whether there is a difference with Arabic and Farsi support. I guess there are some characters in Farsi which are not supported by Visual Basic 6. Have you heard of this issue? Thank you.

Hi
As you may know, there are only 4 characters in Farsi that are not included in Arabic and the other characters are identical. And as I previously mentioned, VB has got nothing to the characters.
What you have heard may be because of Arabic fonts used. Yes, there are some Arabic fonts (that do not support the characters related to letters گ چ پ ژ)
so it is just related to the fonts you use, and not a matter of VB.

Is there an easy way to freeze columns in a VB.Net datagrid. If so how is this done or can some one point me in the right direction of any information. Basically I want to freeze the first 2 columns in a datagrid.
Thanks in advance
|

Hello!
For freezing the coloumns you can use the READONLY property of datagrids.
For this you have to create a datagrid style, create DataGridTextBoxColumn and then add DataGridTextBoxColumn to the style...
Each DataGridTextBoxColumn can be Readonly or Non Readonly.
Check out the following code snippet..
dsData is the dataset that contains a table.
Dim dgStyle As New DataGridTableStyle
Dim datacol As DataColumn
Dim dgcol As DataGridTextBoxColumn
For Each datacol In dsData.Tables(TableName).Columns
If Condition Then
dgcol = New DataGridTextBoxColumn
dgcol.MappingName = datacol.ColumnName
dgcol.HeaderText = datacol.Caption
dgcol.ReadOnly = True
end if
dgStyle.GridColumnStyles.Add(dgcol)
Next
dgStyle.MappingName = dsData.Tables(TName).TableName
Me.DataGrid.TableStyles.Add(dgStyle)
The above code will make the columns readonly depending on the condition.
You can give the condition dependin on clumn name e.g
CONDITION==>datacol.ColumnName = "Title Of Column"
I hope this will solve ur problem

Hey folks, i got a problem...
i got a third party app randomly connecting to 200 different servers.
All servers got a fixed IP that i know.
Now i want that app to only connect to a defined server, lets say server 120.
Is there an possibility to redirect all the other server ips to the ip of server 120?
I don't know if the app has to resolve the ip first but it seems so already tried to manipulate the "hosts" file but the app doesn't care...
If you got any idea pleas let me know... even if its as silly as hell 
thanks

Randomly connects to servers??? What kind of an app is this? It sounds liek you're trying to trick the software into connecting to a specific server because it's a trial version.
Depending on how the app is getting the server names and resolving them, you may not have any options to solve this. What is this utility and what kind of servers is it used for?

No it aint a trial application
i aint a cracker
Its a game that connects to that random servers but one ingame event only happens on a specific server and i want the game to connect to exactly that server...

The only way to do what you want is to write your own proxy server. Your game would have to connect to the proxy server where all packets outgoing to the list of servers that you have would have to be re-written to be redirected to the new address. This is, by far, not an easy task.

You have to wait for the process to completely start before you send keystrokes to it. Instead of using Shell, you might want to use Process.Start instead. This will give you more options, like being able to check if the process has actually started yet.

Hi, can anyone tell me how can I set/revoke the permission to a folder for user in windows using VB.net.Thank you.

There's no support for this in the .NET BCL until the .NET Framework 2.0 comes out. You might want to checkout this[^] sample on GotDotNet.com.

Hi, i need to save to a text file with a variable name. This is what i have at them moment. It saves to mood.txt in the same directory as the project.
FileNum4 = FreeFile<br />
' Create mood.txt<br />
Open appPath & "mood.txt" For Append As #FileNum4<br />
' Write the contents of TextBox1 to mood.txt<br />
Print #FileNum4, mood; " , "; lblTime; " , "; songTitle<br />
' Close the file<br />
Close FileNum4
What i want tho, is for the filename to be "songTitle" mood.txt where songTitle is a varible As String. Ive tried this:
Open appPath & songTitle & " mood.txt" For Append As #FileNum4
But i get a bad file name error when i try to save to the file. Im sure there must be a way to do this, i just cant figure it out. How is it done?
Thanks

If you're going to have spaces in your filename, the entire file path must be enclosed in quotes: "C:\Documents and Settings\...."
Dim filePath As String
filePath = """" & appPath & songTitle & " mood.txt""" For Append As #FileNum4
