okay here's some more info
I added a windows form to the console application and chnaged the project properties to "Windows Application" and it works!!
...but the project I create via File/New/Project...VB.NET/Windows Application - that doesn't work!!! What gives?

|

Is there a way to do this. I have 2 seperate projects that I want to be able to run together, and experienced problems when trying to import all the code into the other one, that and one has different references, so trying to manually import the code is a real pain.
but when I try to make reference to a class in the other project it cannnot find it.
Thanks for the help

Depending on how your projects are written, you can't just "merge" the two together. You'll most likely have to copy the files into one of the projects and modify them to use a common namespace.
The only other way to do it would be to add the two projects in question to the same Solution. Either way, you'll have to modify the code to work.

Please help. I'm writing a small app that needs to capture individual frames of video from a video file to a picture control.
What's the easiest way to do this in VB?
Any help would be greatly appreciated. Thanks. Thanks, and thanks again.

You must install the .NET Framework on the machine first, before you can install your app.
There are a bunch of articles here on CP that deal with installing the .NET Framework with your application. Look at these[^] search results.

I have installed the managed directx sdk version 9. I have written an application in vb.net that displays some very basic artificial life forms that move in flocks around the screen using Microsoft.DirectX.DirectDraw. I am successfully drawing to both surfaces (Microsoft.DirectX.DirectDraw.Surface) and calling the Surface.Flip method to put the buffer surface's content onto the main surface (Surface.Flip makes the surface memory associated with the BackBuffer surface become associated with the front-buffer surface). What I can't manage to do is keep the back surface's content without it dissapearing i.e. I want to carry on overlaying what I am drawing onto it with each flip. I know why it is lost - when a flip is carried out the pixels are blitted to the main surface. I need some way of maintaining it on the back surface. Does anybody know how to do this?

To adapt your engine to this, after the flip, you'd have to copy the image on the surface that's displayed to the back page surface.

Thanks for your reply.
I did try doing that using the Surface.Draw method. This "copies" the contents of one surface to another. However it defeats the object of what I am trying to do because it merely performs the same bit block transfer that the Flip method does i.e. transfers not copies. The main problem I have is finding a way to copy the contents of a surface, retain it and draw it back onto a surface.

Then I don't get what the problem is. In all the code examples I've seen for DX, I've actually had to clear the drawing surface myself before I started drawing the new frame. If I didn't, then I'd se trails of everything. I guess I don't understand the effect your looking for?

Easy. Get the appropriate rights to delete the file. That's the error that was returned. You, or the account that your app is running under, does not have sufficient rights to the file your trying to delete.

Hello,
I created a website using VB.Net that needs the userId value from the textbox from an existing ASP website. The old ASP website didn't declare the userId varible as a session varible.
How do I use request command to read the userID into my webform?
Any help would be helpful. Thanks!

This question really belongs in the ASP.NET Forum, regardless of the language it's written in.
But, if I understand this right, you want one ASP.NET web page to read the values stored in a textbox in another ASP.NET site page that is in an entirely different site (or application)?
If that's true, then you can't. There is no way for the server to query the client machine for what's in one of its textboxes. Once ASP builds the HTML and sends it to the client, all traces of it are lost forever. The ASP page has hidden fields in it that maintain the state of the page and are sent back to the server on every page request, thus telling the application on the server what the values of all the control on the page are. Once the processing on that request is finished, that hidden field is updated with the values that are going to be put into the page and then the page is sent to the client and destroyed on the server.

I want to save an image located on the clipboard to an IMAGE field in SQLServer without having to save to disk first.
When I run the code listed under CASE1 everything works file.
When I run the code listed under CASE2 I get a "invalid parameter used" error.
Windows does not recognize this as an image file when the stream is saved to file after retrieving from the database.
Does anybody have a solution why the FileStream works and the MemoryStream doesn't?
Tim
Dim oImgObj As Image = oDataObject.GetData(DataFormats.Bitmap, True)
'CASE1
oImgObj.Save("c:\Test.bmp", Imaging.ImageFormat.Bmp)
Dim fs As New FileStream("c:\Test.bmp", FileMode.OpenOrCreate, FileAccess.Read)
Dim bImageFile(fs.Length - 1) As Byte
fs.Read(bImageFile, 0, fs.Length)
fs.Close()
'CASE2
Dim ms As New MemoryStream
oImgObj.Save(ms, Imaging.ImageFormat.Bmp)
Dim bImageMemory(ms.Length - 1) As Byte
ms.Read(bImageMemory, 0, ms.Length)
ms.Close()

 I'm a newbie to vb.net (and c# for that matter) but I've been tasked with writing a config app for an educational tool. The app should have a sophisticated gui for configuring hierarchical lists of commands, e.g in the form a of a tree structure. I'll probably need DB access and eventually have to talk to some kind of bluetooth device. I've got pretty extensive experience with visual c++, but that was a few years ago.
My simple question is: what are the main considerations when deciding between coding in vb versus C#? In other words, what are the main limitations/advantages in using vb relative to c#?
thanks

They are basically the same. If you come from the C++ background C# may be easier for you, though.

In the world of .NET, where all the managed languages compile down to just about the exact same IL, there is no difference. Well, there are some things that C# can do that VB can't and a few that VB can that C# can't, but those are language differences. There are really no differences when it comes down to what kind of app you can and cannot code in either language. This minor "gap" will become much smaller in with the forthcoming release of VS.NET 2005 and the .NET Framework 2.0.
It's really a matter of personal preference...

I am writing a custom grid, inherited from datagrid. I use data-binding to populate grid from an ArrayList.
When I click the column header, I am capturing the click and sorting the arraylist and re assign the data source to populate grid with sorted data.
My problem is, I do not get the sort arrow in the column header. How can get this?
Thanks in advance.

There is no icon that is drawn for you automatically when sorting. You can't do it in a DataGrid. Although in a ListView controls Details view, you can. You have to draw it yourself using owner drawn header controls. There are a couple of articles here on CP (though searching for them is nearly impossible right now.) I've seen this done and have done it myself in ListView controls, but never a DataGrid. This will be possible to do in the next release of VS.NET 2005 and the .NET Framework 2.0.

Well, if I set the allow sorting property to true and click on the header column to sort, the datagrid shows the up/down arrow by default. This works fine if my data source is a DataTable. Problem comes when I use an ArrayList as the data source. Any more thoughts on this?
