I think you need ASP.NET web application for that not windows application unless you were to consider Web Service.

This is not possible in ASP.NET. You could inherit from the DataGrid control to and provide your own implementation (heavily augmented with a liberal amount of javaScript) to provide the functionality that you desire.

If you make a menu and then click its properties, you have the option to make an image list. Do this and then add the images you want.

Hi Guys,
I'm new to this thing.
1. does anyone know how to capture the image from a digicam and insert into a SQL server database using vb .net?
2. How to capture the signature file using a pentablet hardware using vb .net and save the image into SQL server?
Pls. Help.

1. does anyone know how to capture the image from a digicam and insert into a SQL server database using vb .net?
You might want to check out Windows Image Acquisition here[^]. No garantee that it will work with your camera though. It would appear that you have to check with the manufacturer of the camera to see what device drivers are available for it and any possible SDK's. You also might want to check for TWAIN compatibility. That should make your life much easier when using the WIA API's.
Once you have the images, it's not that hard to put them into an SQL database. This[^] article describes the process for use with an Access database, but the concepts apply to SQL databases as well.
2. How to capture the signature file using a pentablet hardware using vb .net and save the image into SQL server?
You're probably going to have to depend on the manufacturer for the SDK's and docs for this one. But, once again, when you get the image, the SQL part is easy.

hallo
i try to make a columnstyle for usercontrols. the output for rows in noneditmode should be made by a bitblt of an invisible form. an that's my problem. if a form is not in the visible area of the screen, the bitblt returns an empty graphics. so my question:
is it posible to open a form on a virtual graphics device?
is it posible to get a bitblt from a form out of the visible area?
is there a better solution to do this?
thanks for your help

:-Ohi,
I need help regarding the following application.
1. The application should have a button - "Launch PowerPoint" - clicking it
launches PP.
2. The application has a browse button to select only PP files. On clicking
it, it brings up a file selection dialog in which only the PP files are
enabled for selection. On selecting a file, it opens into PP.
3. The application has a "Play" button. On clicking this, the PP brings up
the slide show.
4. The application has a "Next" button. On clicking this, the PP proceeds to
the next slide in the presentation.
5. The application has a "Back" button. On clicking it, the PP goes back to
the previous slide.
6. The application has a edit field which takes only numbers. A check box
labeled "Custom Timing" enables or disables it. When enabled, the contents
of the check box is taken as the time separation between the slide changes -
if "Next" is not clicked by then. For e.g. if we enter 10 into the edit box
while the PP is playing the slide show, then if we do not press "Next" for
10 seconds, PP displays the next slide automatically. This you do by
changing the slide flow information of the presentation slides.
Thanks and Regards to all of u out there
Ramya.

ALL of this functionality is already built into PowerPoint. Why would you want to "reinvent the wheel"?
Basically, you'll be setting a reference to the Microsoft PowerPoint object Library and controlling it thru code. You can create your own Open dialog and pass that file on to the PowerPoint application object you create. Playing the slide show should be as simple as myPowerPointAppObject.Show(), or something to that effect. The only sticking point is going to be the timing box. You can implement the textbox that only takes numbers very easily, but your going to have to override the presentations built in timers to get the next slide to show up when you want.
Basically, all the functionality you described can be done as part of the presentation itself. All you do in PowerPoint is hit F5 to start the presentation. Click a mouse button or hit any key to show the next slide...

I know this should be simple but I can't get it to work. Isn't there a way to pass command line arg's to a vb.net program without have to use the vb6 class?
I search help but I must haver it installed incorrectly becuase it keeps saying it is updating my recent changes?
Thanks
Tom

Sure. You can use the System.Environment class to get the command line arguments in a String array. Something like this should work for you:
Dim arguments As [String]() = System.Environment.GetCommandLineArgs()
The System.Environment class will also let you get the entire command line as a String, get at environment variables, get and set the exit code of your app, current directory, NETBIOS machine name, ...
Docs on the class can be found here[^] on MSDN.
