• Visual C++ datagridview refresh problem

  Was hoping someone could help with a refresh problem. I'm running a function to update the colours for the rows on the DataGridView in a tabbed pane based on some value from the dataSource of the DataGridView. However the DataGridView will not refresh the first time round. If I move to another tabbed pane and come back then the DataGridView is properly refreshed. What I think the problem might be is that the dataGridView has a few eventhandlers when a user changes the values. So what I did was to call the EndEdit before I refreshed, which didn't work. I've even refreshed the parent of the DataGridView which didn't work as we ...Show All

• Visual C# Logger in multi-threaded application

  Hi, I have a multithreaded application, in which most my classes inherit from a base class. This base class contains a Log()-method, that is supposed to append text to a text box created in the main thread. I know that this is a problem since I can/should only access the textbox in the same thread as where it was created. What I would like, is a thread-safe way to implement the Log()-method in the base class, so that disregarding which child-class and which possible thread I am in, I can call base .Log("Warning, something might be wrong", Type .Warning); and the message gets printed to a textbox instantiated at the ...Show All

• .NET Development ThreadPool and Webclient.UploadValues

  I have an app that listens on a multicast socket for some data then wraps that data in some XML and POSTs it to a web server for storage (the response from the web server contains no useful info so I ignore it). Early on I noticed that using Webclient.UploadValues was taking a fair amount of time and I was missing some of the multicast data coming in. I then tried using a ThreadPool to spawn off a separate thread that created it's own Webclient and and performs the POST for each multicast data item. Is there anything wrong with using ThreadPool with a Webclient this way I mean letting the ThreadPool spawn off as many Webclients as necess ...Show All

• Windows Forms Disable refresh of Control in EditMode upon ItemChanged

  I have a complex business object i'm binding to in my DataGridView (through IBindingListView) which is constantly changing its elapsed time every second. When i try to edit this Elapsed property through the grid, whatever i type into this textbox gets erased with the updated value in the object. What is the best way to disable refreshes on the Textbox once its in edit mode I think the problem is occuring because of the ListChanged from the BindingList getting raised, hence refreshing my datasource forcing a refresh when i'm editing. The only solution i can think of now is to bind my DataGridView ...Show All

• Visual C++ VS2005 C++ project: linkage errors under MultiThreaded-DLL runtime lib', but compiles fine under Multithreaded-DEBUG dll ?!?

  Hi, I am in the process of moving our development to VS2005 from VS2003. One of our C++ projects now runs properly in debug mode, and in release mode when using the multithreaded-debug-dll runtime libs, but does is fails during linkage when in release more and using the multithreaded-(release)-dll [which it is supposed to]. - The project combines managed and unmanaged code. - The error repeats itself both in the original managed C++ syntax, and now in the new C++/CLI syntax. - Other C++ projects I have moved to VS2005 do not have this issue. The linkage error is below in italic. Any ideas ! Thanks, 5spot MSVCMRT.lib(mstartup.obj) : error ...Show All

• Visual C++ CDialog::DoModal asserting in CWnd::DestroyWindow

  To Brian and Martin, who were involved in helping me out with this , please don't shout at me... This thread does follow on from that post - and I'm now investigating refactoring a static library which contains a few MFC classes into a shared DLL - using __declspec(dllexport) to export functions and classes that will be needed across all facets of the solution that need the shared functionality. I've looked all over the place for an answer to this question - and found loads of other people using MFC 6, 7 and 8 with similar problems. I'm not going to be naive enough to suggest that MFC has a bug - I'm well prepared for this being a s ...Show All

• Windows Forms Custom control containing child custom controls

  Hi Everyone, I have a question about the correct way to create a custom control that contains a dynamically controlled number of child controls. Basically i'm trying to implement a basic vector drawing control similar to that found in photoshop/xara/inkscape etc. I have a parent "vector" control that containes a number of "point" controls and "line" controls (where the lines connect the points). I figured this was the best way to do it so I could handle events on each part of the vector itself easily. The problem I have is with the OnPaint(PaintEvenArgs e) overrides. I seem to be able to add my child controls ok ...Show All
