I tried to put it before or remove it. No change. I'll probobly stick with TransparencyKey, which by the way I use on one more place-> Trasparent Flash player. So I need to make it work

Strange, here it doesn't work at all... I think maybe what I am seeing is actually form's BackColor. What did you set it to be (Color.Transparent throws exception)?
UPDATE: Regarding the bit depth/resulution, on some PCs the transparency only works in 16 bit color (on the old Intel onboard graphics). Blasted graphics drivers

Hello,
I'm really confused!
Just made a test project.
)MainForm has a Backgroundimage during DesignTime.
)BackgroundImage is a bmp File designed in Paint (All Black only a Red Line in the middle)
)BackgoundColor is Default "Control".
)No TransparencyKey set
)Following code in the Forms constructor (After InitializeComponents)
Bitmap b = this.BackgroundImage as Bitmap;
b.MakeTransparent(Color.Black);
this.BackgroundImage = b;
)When I start now, I see just the Red line and the Desktop.
)If I move the Form then off corse the Desktop is not refreshing in the Forms region.
All the best,
Martin

So you see the BackgroundColor of your Form right now?
Then I'm sorry for wasting your time!
Hope somebody helps you out.
All the best,

I have tried both 32 and 16 bit color, doesn't change anything on my PC. I will go see if it changes something on the ones that do not work.
Its strange that there is no posting from MS on this, maybe we should post it on their newsboard. If I find a solution I will post it here.
Good luck,
Dmitry

I've tried to go from 32 to 16 bit and it helped!!! But it looks that it's diffrent from one PC to another... And using MakeTransparent didn't help at all...

If you are using NET 2.0 version then create a typed dataset and add as many table adapters as you want and use the same process if you want to go for dataset also
And for the next query "Is it possible that i can bind more then one DataSet in a single datagridView"
datagrideview takes data source as either data table from a dataset not entire dataset !!

Hi,
I'm looking for some tutorial how to handle COM objects in C#. I've found good articles about how to create COM objects in C#, but couldn't find any about using those objects (whether created in C# or C++ , doesn't matter). Thanx (for link )
PS: I know that there is COM forum, but I didn't get any answer for 5 days there.

It's quite simple. Assuming that you are using Visual Studio:
- select your project in the Solution Explorer
- choose Add Reference
- in the dialog that open select the COM tab
- choose your COM object and click OK
VS automatically creates a .NET wrapper for the COM object that you can use from your code. One drawback of this method is, that this wrapper has no signature.
If you need a strong named wrapper, you can use the tool TlbImp.exe. Its use is well documented in the MSDN.

Tim

Hi,
Yes I'm using VS 2005 Express...
The COM-object I created is not among all COM's in COM Tab (in diffrent project). Do you have any idea why? (When building that object I checked Register for COM interop in Properties->Build and I also created strong name object using sn.exe utility... )
thanx

Sorry, I've never written a COM server in C#. All my COM objects are 'older' unmanaged code that is used from within C# projects.
Generally all COM objects must be registered on the PC before they can be used. And all registered COM objects should be listed on the COM tab. Therefore I guess, that your COM server is not registered properly yet. But this is just a guess.
Have you already tried to use your COM object from some other (unmanaged) code?
Regards,
Tim

No haven't but I'm planing on that. First I wanted to try this all under C# and VS2005, thought that it would be easy, than go to C++ , create COM and use it in C# same way as COM created in C#...
|

|

I've tried TlbExp.exe and opening COM object with browse button or registring that COM dll using Regasm.exe and still no luck...

If you are checking Session["userId"] on every page to be valid, then the user may not be able to go back and use the pages by clicking on IE Back button

I want to mask the text for identifying the corrent syntax of IP address

Hello,
A quick validation would be to split the string (string.Split('.')) and chek if the elements of the array (return value of Split method is string[]) are not longer than 3 characters.
Additionaly you could also check the Length of the string[].
Hope it helps!
All the best,
Martin

Hello again!
Here I found a very nice solution with regex!
public bool IsValidIPAddress(string ipAddr) {
string pattern = @"^([1-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])(\.([0-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])){3}$";
Regex reg = new Regex(pattern, RegexOptions.Singleline | RegexOptions.ExplicitCapture);
return reg.IsMatch(ipAddr);
}

I don;t know the exact answer but this might help you ...
Create MS Word object
use the save as method of MS Word object, pass html as parameter
Hopefully this should be the approach

This is probably the only way, however I believe it is really a bad practice!
It relies that a correct version of MS Office with MS Word is installed by user, and depends on the interface provided by that specific version. I don't think there is another way however, since DOC format is proprietary, and theoretically only Word engine should know how to parse it.
