• Visual C++ Exception managed/unmanaged

  Hello, Using IJW technology, I have a .NET program on top of a C++ code. A C++ exception (derived from std::exception) is thrown in the C++ part. In the managed part, I get a SEH exception, but can't find any way to get the additionnal information (the what() string, or the real type of the exception, runtime_error, bad_alloc...). Is there any way to get this information Best regards, You can't, but you can add a separate catch in C++/CLI. class UnmanagedClass { public : UnmanagedClass() { throw new std::invalid_argument( "this is a test" ); } }; int main( arra ...Show All

• Windows Forms Custom control with data binding sample

  Hi everyone I am trying to find a nice and simple example of a custom control that supports complex data binding (like a simple grid or a listbox). Surprisingly, I couldn't find anything useful in the SDK nor on the Web. All the sample either really trivial (SDK) or incredibly complex (Web).  What I am trying to do, is to create a custom control&n ...Show All

• Windows Forms ListView and subclassing

  I have read two excellent articles on how to subclass .NET controls so that you can hook into the control’s WndProc, which is very helpful since you cannot access the WndProc directly for .NET Compact Framework controls. The links are: http://blog.opennetcf.org/ayakhnin/CategoryView.aspx category=ListView http://blogs.msdn.com/netcfteam/archive/2005/07/24/442616.aspx Sub-classing allows you to trap windows messages and provide handlers for them. I have run into a difficulty though when trying to request owner drawn messages. I have a listview control that I have sub-classed. The reason that I did this i ...Show All

• Windows Forms Progressbar on a different thread

  Hi all, Im kinda stuck here. Let me tell you some background info. Users can create a shift, but within that shift they can create a recurrence pattern. Now, those recurrence patterns can be long, like from 1 january till 1 february. What the program does is it create's a copy of the orginal shift, change's the dates and inserts it into the database. This take's some seconds and i want to popup a progressbar. The shift saving stuff all occurs within the UI thread ( i know..im going to seperate that ) When the saving starts, a form show's up with the progressbar. But the thing is, it won't show up very nicely as it is loading when the sh ...Show All

• Smart Device Development Getting "Registration failed wirh error 0x8973190e. Error writing file" ... Error 0x80450001

  I am trying to register a simple sample grabber filter that I wrote for WinCE 5. It compiles and links fine and I can copy it to the remote device or emulator. But when I try to deploy the DLL I get the error in the title. Any ideas Thx, Tom Are you deploying all your dependent libraries Check out depends.exe to see what you are dependent on (ignore msjava.dll, that's not a real dependency), and make sure they are all on the device and locatable by your app. If they are all present, then the next step is debugging your registration calls. * Switch the register output property on the deployment property ...Show All

• Visual C++ Managed class in a MFC ActiveX control

  I have a MFC ActiveX Control peoject, and I am trying to create a managed class within the control project with the /clr option. The code compiles and links without errors. So now when I am trying to add reference to the ocx in a C# project, I get the interop stuff the COM control class, but nothing for the managed class.

Would anyone have suggestions on how to solve the problem so that I can access both classes You could just leave it this way, there's no need t ...Show All

• .NET Development Memory usage

  I've noticed while profiling apps that the Process/Private Bytes counter keeps going up.  The .NET Memory counters (Gen x heap size | # Bytes in Heap | etc) all go up and down as the app runs.  Other than some very small dips the private bytes continues to go up and up as processing is done.  Does this represent some type of memory leak   I'm not using any unmanaged code that I'm aware of either. Thanks Chris I will try out those tools.  Not sure if its a managed memory problem as I can see that the heaps are collected (or at least the heap size has gone down) while the private ...Show All

• Smart Device Development httpwebrequest https Proxy Authentication issue

  I'm using VS 2003. With a Dell Axim x51 (with Windows Mobile 2005) It has embedded in the rom CF 2.0 (i believe). The proxy address is port 80, and I'm given an IP, username, and password. I can use the Pocket IE on the device and get through. However the following code yields... different responses when attempting. Sometimes I get 407 error (which is enter proxy credientials), or a timeout, and if you notice I increased the request timeout to 6 minutes. Or if I try to hit a 443 address. I get immediately 'can not estasblish a secure connection for SSL'. The proxy server uses NTLM authentication (at least in one of our cases) There are publ ...Show All

  Hi. I tried at the "regular" DirectX forums but since there was no answers or even faint ideas I am gonna post my question here.

You need to restart the program." I am using MSDE 2000. The OS is Windows 2000. One thing I noticed is that sqlmangr.exe will not crash if I disconnect the system from the NETWORK.
