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.

Well thanx for your reply

Hi all,
I want to interact to PCI device by C# project , but I don't know were way to implement it.

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.

Is it possible to conduct unit tests for interfaces in ,net framework other than constructors, classes, methods? i would appreciate if anyone can provide a clue to me.
|
|
|
|
|
What do you mean by "unit tests for interfaces"?
Interfaces, by their very nature, will not have concrete implementations - so what are you going to test?
Cheers,
Vikram.

great answer. I am not sure if the topic is user interface or interfaces. Wow it is easy to get it confusing.
|

I am assuming you are discussing the unit testing of the user interface of an application web or winform. There are open source and commercial products which address this however they are not as complete as one would hope. For the last two years I have been using the MVP pattern which allows me to provide a richer level of unit testing for the controls on the user interface.

Previous to this I used the MVC pattern which provides much of the same benifits. I have used the open source asp.net and win forms unit testing tools but they are difficult to get the level of results I was looking for.

I'm working with two dataSets, one I used the VSC#Express wizards and editors to make the tables, tableAdapter, and bindingSet, and the other i just used the wizard to make the dataset, and am making my own tables via code. The second uses no table adapter or binding set. The first will save it's data to disk when the program exits, while the second doesn't. With the second, I am calling AcceptChanges() on the dataSet each time I change a table or row, and while the program is running i can retrieve the data just fine. But I can't get it back next time i run the program. Any help would be appreciated.

I have to determine the current scrollbar-position of a richtextbox but i don't know how.
Can anyone help me please?

Hi!
You'll have to send EM_GETSCROLLPOS to the RichTextBox via P/invoke.
Here's the description on MSDN.

Hello everyone,
I have added Speech Recognition to an Windows Application and it works just fine when I run the Windows Application on Windows XP Operating System. The very same Windows Application faces a problem when it is run on Windows Vista since once I enable the Speech Recognition on my Windows Applications, it automatically turns ON the Speech Recognistion on the Windows Visa.
This means the commands are both used to run action in my application at the same time with Windows Vista grabbing the same command to run other stuff.
I was wondering is anyone has experinced anything like this or if there is any way to simply switch off the speech recognition fed into Windows Vista command center without disabling the speech recognition in my Windows Application?
Thank you very much and have a great day.

There is a Vista forum. Your question does not relate to C#. Please post it only in the forum where it belongs. This seems more lounge to me than anything, to be honest.

He'd be burnt to a crisp if he posted it in the Lounge.
Not saying it's right or anything, just making an observation.
