Better yet, Amazon and get yourself a couple of good books on VB or VB.NET, whichever your using.

If my datagrid is readonly = true.
Then it cannot be modified from inside datagrid but i want to allow deletion of row if 1 or more rows are selected and this is event raised after a button is pressed.
How to code this?

Is there any free tool that can convert my vb.net forms to asp.net

If your code is well written, you should be able to just write an ASP.NET presentation layer, but as has been said, it's a totally different model, and the way you code it is way too different for a wizard to deal with.

I have a windows apllication which has flexgrid.This application works fine when it is run from the local hard disk.But when this application is accessed from another computerin the network it gives.System.security.securityexception
Using try catch i found the error was Request failed
What i actually want is deploy my application on one machine and acces it from other machines without deploying on each and every machine

Why does the flexgrid give a security exception ? Is the error message wrong, and you just need to deploy the grid ? ( Flexgrid isn't a WinForms control, it's an old one, isn't it ? )

You really can't do that with the presentation part of the code, although you can do it with your data stuff, if you can configure all instances of the app to look to your machine. This means you need to code for concurrency issues, obviously.

Hi all,
I have given an option of deleting a row of a grid by pressing Ctrl-F6
But this key is not working
The same function is getting called by other keys like Ctrl-F7
Since Ctrl-F6 is a windows shortcut key to toggle through windows,so how to disable this key of windows.
Please get me a solution
Thanks in advance

I am trying to use the ms internet transfer control to download binary files from the internet using the execute statement. I am only using a very basic piece of code as a test, however by using the debugging tools, and stepping through the code one line at a time, the Inet controls statechanged event is not called. The execute statement is
Inet1.Execute URLname, "GET"
I have tried setting the other properties of the inet control to no avail. In addition I thought about adding a piece of code either before or after the code to make sure the inet control is not currently executing, something like
If Inet1.StillExecuting = True then
DoEvents
End If
If anyone has any thoughts on what is going on I would be very appreciative,
Cheers,
Mark

I want (desperately) to do something very simple (i think or at least thought.)
I want to have a web page that simply has a link that you click, this runs a command line app and then returns the output to HTML.
{ie click here the and the system shows you the contents of C drive. Or shows you custom enviornmental settings.)
I just want command line interaction I do not want WMI workarounds (I figured how to do that on my own.)
I want to use VBscript... i know how I would do this if i could use Perl... the coding is not my actual issue, it is the nuances of VBscript and Command line interaction.. alas Perl does script to command line and back so much more smoothly than VBscript seems to but I am a newb with vb altogether...
Thanks very much for you time!

I have been trying to get this api to work in VB.NET, but have no clue how. I have the equivilent code in VB6, but can't get it converted to .NET. If anyone has an example, or know how to do this in VB.NET any help would be appreciated.

Enes,
I am trying to do the exact same thing as yourself. I feel that I am close to a solution, it's just not 100% correct. I am trying to get NetSessionEnum working with level 2 or 502.
I get the data and correctly populate the structure with the first session's details, but when I go to populate subsequent sessions the data is being loaded into the wrong fields. My structure appears correct according to Microsoft's web-site.
If I get it working correctly I'll post the result, hopefully you can do the same if you beat me to the solution.
Regards,
Paul T.

Does the above work for you? Api function always returns a long number 267964182123512921, or some other number depending on whether i use local or remote computer. Do you have a fully working module or a class? I'm not too good with APIs, so I don't think i will be able to figure this out. You can drop me an e-mail at enes@qwest.net if the code is too long to post here.
Here is my API function decleration.
Private Declare Function NetSessionEnum Lib "netapi32.dll" (_
ByVal lptstr As String,_
ByVal lptstr As String,_
ByVal lptstr As String,_
ByVal dword As Long,_
ByVal pbyte As IntPtr,_
ByVal dword As Long,_
ByRef pdword As Long,_
ByRef pdword As Long,_
ByRef pdword As Long) As Long
Thanks,
Enes M.

Enes,
The code I submitted does work for me. I have run it from a Win XP machine and received the correct details of a Win 2003 Server. Be careful of the level that you use because some older OS's won't run level 502, in this case you have to use level 50 which has a different structure. My apologies for not including the API declaration originally.
Private Declare Unicode Function NetSessionEnum Lib "netapi32.dll" (_
ByVal ServerName As String, _
ByVal ClientName As String, _
ByVal UserName As String, _
ByVal Level As Integer, _
ByRef Buffer As IntPtr, _
ByRef prefmaxlen As Integer, _
ByRef entriesread As Integer, _
ByRef totalentries As Integer, _
ByRef ResumeHandle As Integer) As Integer

I`m trying to get picture from text. I need this to log on to my game, anyone knows how to pull it off ?
image text: http://www.void.rs.ba/gra.jpg
so i need to extract "LeechTower" or any other text from it
|
|

You'll need to implement some kind of OCR. There is an article here on CP, just search for OCR. I hope you're familiar with neural networks...
There is a problem with your image though. The lines going through the text will make it virtually impossible for ANY OCR implementation to see the text. You'll have to preprocess the image to make the text standout against the background before you try an OCR pass.

hi,
Iam doing one small project in VB.NET.In that i want to give the command in TEXTBOX and the output should be displayed in RICH TEXTBOX.I need the code for this synario.pls help me in this regard.....

This is nowhere near enough information to help you with anything. What command? What are you doing to generate output? What is the output supposed to look like? What is it that your application is supposed to do?
So far, all you've said is "I want to type a command in a Textbox, do some processing, and write some output to a RichTextBox." Easy, RichTextBox1.Text = "some output..."
