• Smart Device Development Porting WORKING MFC Application and depricated classes

  I am trying rather unsuccessfully to port a WORKING eVC4 MFC application to VS2005 under the Mobile 5.0 SDK. It would appear that microsoft has dropped some classes from support in the latest version of MFC. The two that are hitting me the hardest right now are CSplitterWnd and CEditView though I assume the CDumpContext is going to come around to be pretty troublesome as well. Are there replacement classes that we are supposed to use, or are we supposed to rewrite MFC ourselves to make this work Has anyone successfully overcome these issues that would care to share some strategies Hi, It is true that some of the classes h ...Show All

• Visual C# How do I listen for an event from a CustomizedTextBoxCell at the DataGridView level

  Ok, After a lot of pain trying to override the default handling of EndEdit and BeginEdit in the DataGridView, I gave up and ended up creating my own custom text box cell class with its own ExtendedEndEdit, ExtendedBeginEdit, and ExtendedCancelEdit methods. Even went so far to implement an animated cursor and handling the keyboard events, arrow keys, etc. to move the cursor around and I am sure one of you will tell me a WAYYYY easier approach now that it's almost working. I have got this custom edit mode working, and cursor moves around, draws the text etc.. and I have also defined some custom events to fire to let others know of Editin ...Show All

• Visual C++ Framework 2.0 pin_ptr problem after migration from 1.1

  Hello, We have just done our migration to framework 2.0 and found that some of legacy C++ code does not work. After debug into the code, we found that the problem seems to be in the pin-ptr.

• Visual Studio Express Editions I want obfuscation!

  I have looked everywhere to see if I could find out if VS 2005 will have a better obuscator.  Does anyone else know if the VS 2005 will even obfuscate at all (I'm adding the word obfuscating here for other searchers). I must disagree for it. If I'm right, at the moment, you can sell the software made also with Express, with GoLive license. The limitation of GoLive license is simple. You CANNOT redistribute .NET Framework 2.0 with your apps (or ClickOnce setup). The people will use your software, must download fro Microsoft website previus a registration. That's what I understand reading the VS2005 page . ...Show All

• Windows Forms Stange Checkbox Behavior: Text disappears when AutoEllipsis should appear

  I am experiencing strange Checkbox behavior in .NET v2.0 RTM. I have a standard Checkbox with Autosize = false, AutoEllipsis set to true. The Checkbox has an Anchor value set to Top, Left, and Right, so that when I stretch the Checkbox's parent form horizontally, the Checkbox's width increases. When I shrink the form, it decreases. I get to the point when shrinking the form where the Checkbox is resized so that it cannot display the entire contents of its Text value. This is when I expect to see the AutoEllipsis appear, as it does for Labels. Instead, the whole Text portion of the Checkbox disappears! I don't think this is the normal beha ...Show All

  I have created a database that has a JOBS table, each row of the table has corresponding records in a JOB_TASKS table. Each job may have a different number of records in the JOB_TASKS table. I am trying to create a query that returns a few fields of the JOBS table, then searches the JOBS_TASKS table for all related records and uses those records to create additional column names back in the query and fill in the data in the correct columns.

• Visual C# Interface code completion using C# vs.2003. . .

  sometimes when I inherit an interface I get the tool tip asking me to hit tab to implement. But other times I dont. Sometimes when I dont get the tool tip I erase the inherited interface and replace and I get the tool tip. the behavior is erratic and makes no sense. Any Ideas is there a technique (key stroke combo) where if I didnt hit the tab I can click on the inherited interface, hit a key stroke and the implementation will be generated Blair - There isn't a way to do invoke this explicitly in 2003 but we've tried to tackle some of these issues with the new smart tag implementation in VS2005.  Anson's explained this well her ...Show All
