• Syed Mubarak Ali 'Unable to Load DLL' that a control depends upon at design time.

  Hey, I've had this problem a few times recently. I'm working with Visual C# 2005 Express Edition. I have a Windows Form Control that depends upon a legacy DLL file. At runtime the behaviour is fine as the DLL is in the output directory, but the Windows Forms Designer struggles with this control. Unable to load DLL 'scilexer.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E) The odd thing is that it managed to create the control fine in the first place, but subsequent attempts to edit it fail. The dll file it depends on has been added to the project, is in the main project directory and is in the bin\Debug directory. Do I need to put it somewhere else for the designer to find it   ...Show All

• Senkwe Chanda Attaching unmanaged window handle with managed object

  Friends, I've a Win32 handle of a window of type SysListView32 . I want to attach this Window handle to .NET managed object of type ListView . Back during the days of MFC/C++ this can be done something like: CListView *pListView = (CListView *)CWnd::FromHandle(hListView); int itemCount = pListView->GetItemCount(); How can i do the same in C# The reason behind doing so is that i want to call the methods of ListView object to perform operations on ListViewControl such as getting number of items, clearing all items e.t.c. I don't think you can. The ListView control won't let you assign the Handle property. .NET controls need to keep control over the handle so they can re-create them when the control's style chan ...Show All

• MEder DataGridView -- deny user ability to resize column headers?

  I'm amazed I even have to ask this question, but try as I might I can not find a way to make it so that the column headers are not resizable. Is this possible Currently the user can click and drag the lower edge of the column header and make it any size they want. I do not allow the user to resize regular rows, apparently this does not apply to the column header row though. Yeah I feel dumb. I just found it It's actually ColumnHeadersHeightSizeMode, set it to DataGridViewColumnHeadersHeightSizeMode.DisableResizing to lock their size. Thanks! Hello All. MattGreer88: If you want the columns themselves to be fixed, in the DGV's Property page, set AllowUserToResizeCo ...Show All

• Whoisit HTML Based Label Component?

  Hi All Does anyone know where I can find/buy a component that will display a label with HTML... so if I were to write "<b>Title</b><br/><br/>Description" it would look something like this... ************ Title Description ************ If it had the ability to use HREF's and have an event listener that would be AMAZING!!!! Thanks In Advance Mike Sorry for not being specific I mean one for Windows Forms, (It's pretty simple in ASP)... I am not looking for something to display a full web page, just really a component that acts like a label but I can have multiple formatting (Half Bold, Half Italics etc...). I only thought of HTML because that probably would make the most sense. I tried using the RTF ...Show All

• rbearry Can't get DrawItem event any more, in some special case

  This interesting thing was found by use of DebugView to monitor the all events. Suppose that there are 2 controls, one is propertyGrid, one is myListBox, which is a subclass of ListBox. myListBox uses OwnerDrawFixed mode, so it has to draw all items manually. However, in some mysterious case, I found that when I repeatedly opened and closed the propertyGrid, myListBox may never raise any DrawItem event. I output all events to DebugView, then found that WM_PAINT was there, but didn't WM_DRAWITEM. Also it can't restore from this bad status no matter what I did (move, refresh, resize, maximize, minimize...), until I recreate another myListBox. I think WM_DRAWITEM is nowhere to be manually emitted, since it's managed by control. ...Show All

This filename points to another XML file that contains all the information for that package. ***I do not want all information for all packages in 1 XML file, because that file will get longer than 600,000 lines in a ...Show All
