You can set a keypreview property on the form, I thought, which means the form gets to preview all keys.

As far as I know there is nothing as easy as simply enabling KeyPreview. Instead you'll have to use hooks that however are well covered by many internet resources. You can start from this CP article Using Hooks from C#[^]

Hi,
Is there any way to Print the contents of a Picture Box?? Its not just printing the Image of the picture box.
In my application i am dynamically placing label controls inside the picture box. Each label have a background image. I want to print the image as well as the labels inside the picturebox .(means as we see in the display)..
OR
If the above is not possible.. then is it possible to draw something using graphics (eg Rectangle) and take printout of that also along with the image.
Thanks in advance.

Why are you doing all this inside a picture box instead of a paint handler ?

i have preloaded images (jpg files) which are layouts of different locations. the user will mark positions on the image and associate some values with the marked position. After marking the locations he want to take the printout with the marked locations.
This is the requirement. Can any one can help me??

OK, so why use a picture box ? Why not just draw it yourself and let the existing printing framework print it from there ?

Hi Graus,
the layout images are external jpg files. (eg: Layout of a building). I am loading the same to picture box initially and user can mark locations on them. Then he want to take the print out of the image along with the marked locations.
It would be fine if you can help me for creating .Net c# code for the code found in the following link.

Thanks

Hi,
I typically use a Panel to do such things.
Graphics.DrawImage would show the image, Graphics.DrawString would add some text, etc
(all inside the paint handler).
And then printing would print exactly the same things, since it too calls the
paint handler.

Hallo NG,
I have a VB6 ActiveX DLL which is calling a Method of my C# Application. One Parameter of this method is defined as Object.
void Foo (ref Object obj)
In special cases the parameter obj contains an two dimensional array of integers. I need to change the values in this array before I return the control to the VB6 DLL.
The problem is that I can change the values in the array in the C# part, but when the control comes back to the VB6 Dll the array contains just values of zero.
I think it is a marshalling issue, but I don`t know how to solve it.
Maybe somebody has an idea.
Here is the Interop Assambly part:
.custom instance void [mscorlib]System.Runtime.InteropServices.TypeLibTypeAttribute::.ctor(int16) = ( 01 00 D0 10 00 00 )
.method public hidebysig newslot abstract virtual
instance void gNotify([in] class srvUIConst.UIInterfaceClass marshal( interface ) oNotify,
[in] int32 lMSG,
[in][out] int32& lParam,
[in][out][opt] object& marshal( struct) vParam) runtime managed
The parameter I was writing about is the last parameter (vParam).
Thanks in advance.
Regards Martin

Hi,
I have made an application in C# which captures data from ListView control.when i test this application,for some ListViews it gives correct data but for some it crashes the other application whose data i try to retrieved.
I have read somewhere that if ListView control is owner driven then i wont be able to get that data,i dont know whether that is owner driven or not
if that is owner driven then can anybody knows the solution or if there is any other problem then please guide me.
Thank you.

If it's owner drawn, then you have no idea where the data is stored, and there's not much you can do.

Hi all,
I want to interact to PCI device by C# project , but I don't know were way to implement it.
Device name is Digital Video Recorder
Please help!

You will find that you want to use layers of abstraction for this sort of thing. In this case, you want to use DirectX. Your code will not care that the device is PCI, it could as well be USB.

Once again, I find myself reiterating my answer. You need to download the DirectX SDK and look at the samples in there for working with video. There are many samples on Code Project, probably better than the SDK ones.

Thank Chistian Graus
I did try with DirectShow but it do not looking for my device.
DsDevice[] capDevices;
// Get the collection of video devices
capDevices = DsDevice.GetDevicesOfCat( FilterCategory.VideoInputDevice );
Let for me any sample also it.
Thanks, Again.
