Hi Stephan,
Thank you for your reply.
The error did exactly tell me whats wrong, but the tables im trying to reference are in my dataset.
<root>
<test>
<id> </id>
<date> </date>
</test>
</root>
So i tried deleting the table test. That is a table right?

I'm new to C# (using 2003 .NET) and I was trying to create my first user control. Inside the User Control I have a toolbar which I would like to dock on the left. When I do so, the images inside my toolbar do not show, but the text does. I inserted the images by creating an imageList, which I reference in my toolbar and index on each of the buttons. I can see the image on the design view, but they never show when I run. I can choose to dock the toolbar on top, or on the bottom and then both images and text show. I would appreciate any ideas.

I'm not 100% sure, but I recall this might be a known bug. Try search the MSDN for details.

Using VS2005 and winforms. Have a TabControl with five TabPages. One page consists of labels and textboxes only. My users want the ability to print this TabPage. Not familiar with printing. Any easy way of doing this? thanks, gary

You could either write your own paint routine, or you can do the equivelant of a print screen by copying bits of the screen to a bitmap through API.
This is some VB code that I used in one of my other applications:
Public Function WindowCapture(ByVal form As Form) As Bitmap<br />
' Get this form's Graphics object.<br />
Dim me_gr As Graphics = form.CreateGraphics<br />
<br />
' Make a Bitmap to hold the image.<br />
Dim bm As New Bitmap(form.Width, form.Height, me_gr)<br />
Dim bm_gr As Graphics = me_gr.FromImage(bm)<br />
Dim bm_hdc As IntPtr = bm_gr.GetHdc<br />
<br />
' Get the form's hDC. We must do this after <br />
' creating the new Bitmap, which uses me_gr.<br />
Dim me_hdc As IntPtr = win32api.GetWindowDC(form.Handle)<br />
<br />
' BitBlt the form's image onto the Bitmap.<br />
win32api.BitBlt(bm_hdc, 0, 0, form.Width, form.Height, _<br />
me_hdc, 0, 0, win32api.SRCCOPY)<br />
bm_gr.ReleaseHdc(bm_hdc)<br />
<br />
' Return the result.<br />
Return bm<br />
End Function<br />
All calls to the win32api class are API calls or constants that can be found in the program APIViewer

Hello,
I started an appl. for a touchscreen, where I designed a alphanumeric input pad.
When I now Click the Button for "a" I have to use the string.Insert Method to get the "a" in my text.
It would be much faster, if its possible to force this Event directly in the TextBox.
Thanks for your time,
Martin

It is impossible to fire an event on an object from code outside of that object. You might want to try calling the SendKeys.Send method.

First, thanks very much for your answer.
After the Buttonclick, I just had to set the .Focus() on my TextBox and then the .Send Method.
This works fine.
But is it also possible to simulate a cursor movement by using a Method like this?
Thanks again for youre time

You can use the Cursor.Position property to set the location of the mouse cursor.

Sorry,
What I meant was the "Cursor"-Key Up,Down,Left and Right.
This should influence the SelectionStart Property of my TextBox.
Thanks for your help,
Martin

What you are referring to is called the "caret" - the "cursor" is what the mouse moves. Outside of setting the SelectionStart property, I am not aware of any managed API which moves the caret. If SelectionStart does not do what you need, there might be some Win32 function that you can PInvoke. Check out www.pinvoke.net[^] for info about that.

Perhaps you can call SendKeys.Send and pass in a symbol representing one of the Arrow keys. That might move the caret, too.

Thanks a lot.
It was so simple just for example: SendKeys.Send("{UP}");
I think I have to parse my code now for cleaning all this dirty workarounds I made the last week.
Here I found a good list for the Symbols.

So again,
thanks a lot for your help and time,

Use NSIS [^]which will run on any system and you can use it as a bootstrapper for the actual installation. 
Of course I'd say use NSIS from the start since you have complete control and it doesn't require anything special to run.
That's one way around it, I'm sure there are others.

Hi there,
I'm looking for a .NET based sample application which is using the SkyWave
API functionality to get the tracking data (position data) from the SkyWave server.
Is there anybody here to know such this sample application?
I've asked it from SkayWave support center (support.skywave.com) but their supports are not too good.
Thank you in advance.

Hello,
I am writing a windows form app using c#.
I would like to create a new data row in a regular c# class using the following code.
public void addWell()
{
DataRow row = new DataRow();
}
But I keep getting this error: "'System.Data.DataRow.DataRow(System.Data.DataRowBuilder)' is inaccessible due to its protection level"
Does anybody know how to change the protection level of the DataRow?
thanks!
rc

You can't instatiate a new DataRow object like that, it's constructor is protected and you can't do anything about that. If you want a new DataRow you must use your DataTable.NewRow() method which will return a new row that has been initalized with your tables schema (i.e. all the columns have been added).
|
|
|
|
|
that worked. thank you!!!
|
|
|
|
|
i am using it in the webpage is that ok
can you please suggest me as soon as possible
|
|
|
|
|
The solution of this problem is to use :
DataTable dt = new DataTable();
DataRow dr = dt.NewRow();
