Hi,
suppose you have set
<br />
Dim ObjCrystalR as NameofYourReport<br />
Then you just have to do the following :
<br />
objCrystalR.PrintOptions.PrinterName = strNomPrinter<br />
objCrystalR.PrintOptions.PaperOrientation = CrystalDecisions.[Shared].PaperOrientation.Portrait<br />
objCrystalR.PrintToPrinter(1, False, 0, 0)<br />
This code will set the Printer to strnomPrinter.
Change the orientation
And finally, printer 1 time the page.

In my application, I have used an applicaton specific file extension for a binary file. I would like to add a unique icon to these files. I have looked in the MSDN in vain for instructions on how to do this. Can anyone help me?
Thanks!

If you mean that you a specific icon in Windows Explorer, you just have to create an entry in the registry.
Can have a look at HKEY_CLASSES_ROOT\htmlfile for exemple.
In this example, you will see how to set an icon (DefaultIcon) and see how to lunch an application when double click on it (Shell->Open)
For the icon, you have to option, a separate file ar included in your exe file. I you want to use second option, you will have to modify the propertie of your icon file in the projec Explorer of Visual Studio. You have to change the Build Action in Embedded Resource
Hope it will help you !

Apparently, .Tables(0) actually refers to a table call 'Table' and not what you think it should by using index 0 of Tables(). You'll have to trace into your SqlHelper class and figure out what's causing it to return the wrong table or multiple tables in the Dataset it returns.

Hello! Everybody
I want to drag file from FileList Box from VB.NET forms to AUTOCAD (or any other application). Previously I did this useing OLEdrag but in .net OLE is obsolute. I need help. I will be greateful if anyone provide.
Thanks

See the DoDragDrop method for more information, as well as an example. .NET encapsulates the OLE drag and drop into (overly-)simple calls, also making use of the DragOver, DragDrop, and other related events.

I tried everything, I can drag and drop Text But I can not drag and drop files. U can try and test sample with windows explorer. If u can with explorer just send me sample code.
thanx

I've done it easily in the past. The only stipulation - without having to P/Invoke OLE's DoDragDrop function and the related OLE interfaces - is that you must have a file related to the item in your ListView. For example, lets say you store the actual path of the file in the ListViewItem.Tag property, so in the event handler for ListView.ItemDrag, you could do something like this:
Private Sub listView1_ItemDrag(ByVal sender As Object, ByVal e As ItemDragEventArgs)
Dim path As String = CStr(e.Tag)
Dim do As New DataObject(DataFormats.FileDrop, path)
listView1.DoDragDrop(do, DragDropEffects.Copy)
End Sub If your ListView contains "virtual" files that you need to stream to the drop target, you have to revert to OLE drag and drop, which can be done using P/Invoke and COM interop for declaring the related interfaces and structs.

While a single string should work, also try a String() array with one element - the path. This does work. I've used it many times. Just make sure the file actually exists, since the .NET FCL doesn't expose other STGMEDIUM types (streams, storage, etc.).

I am trying from last 1-2 days. But Explorer does not recognise and can not perform actions like copy/move. As soon as I started dragging a file from windows (VB.NET) application to Explorer ICON gets changed but it does ot perform any action for file copy OR file Move.
If anyone can provide me a sample code i will be very gr8ful.
Thanks

I have a page where I am uploading an image. When the page is first called, the current image is displayed, after they upload a new one image, the new image is displayed. Here is my logic, When I use the code in red, the image displays and refreshes after hitting upload when working on my local computer. But when I move it over to the server. I get the broken image icon for the images. So I used the code in green and the images would show up fine. But I have to hit refresh after I upload to get the new picture to display. The code in blue is where i view the uploaded picture. Also the ConfigurationSettings.AppSettings("PhotoPath") 's value is

I am using VB.NET Standard edition and it doesn't have Crystal reports. My question is how can i create report in vb.net with out crystal reports? If any one has any examples, I would really appriciate it.
Thank you,
Santana

YES, possible. You can use the datagrid, and other normal controls to print your own reports with custom alignments etc 
He who controls others may be powerful,
But he who has mastered himself is mightier still.

Hi,
Alrite, I found a way to kill the process (hidden). But now I see that the application which kills this process hangs because the process which I just killed (cmd.exe) basically was executing compile commands using gcc, g++, etc. So in the task manager, I see that cmd.exe disappears because I killed it, but I also see g++.exe, cc1plus.exe for a second or so, and then they disappear too.
Also the whole CPU time is taken up by this application, when it hangs.
So I think that the application hangs because the other processes started by cmd.exe stay for sometime before exiting.
Is there a way to kill the main window (cmd.exe) and all the related threads/exe attached to it?
Thanks.

Yes it was, and is documented. No external process can query text when the EM_PASSWORD style is set. In order to do so, you must "inject" your code into the application's process space using system hooks or valid plug connections whereby the application loads plugins into its own process space. There is an article about this in CodeProject if you search.
