• Windows Forms DataGridView Problems Adding New Row

  I have a DataGridView and I set the EditMode to EditOnEnter.  I am also using the DefaultValuesNeeded event to poplulate each column in the row.  If I tab accross the new row and off of the DataGridView the new record is not added and when I set focus back on the DataGridView a System.InvalidOperationException is thrown.  But if I set the EditMode to EditOnKeyStroke this error does not occur. Is this a bug or is there something else I should be doing when the user tabs off the new row   If this is by design what should I do to avoid the exception Do you perform any validation in y ...Show All

• Visual C++ Convert {1,2,3,4} into separate integers 1 2 3

  I need to convert user input "{1,2,3,4}" into separate intergers 1 2 3 4. Can you give me some hints to get there Thanks. Hi, you have different ways of doing that: 1- use the strtok to split by ',' and go through each element and discard all unwanted chars like spaces and '{' or '}' and use atoi (for integers) or stringstream if you want to use streams. Example: int val[256]; // this should be dynamic (count the number of , and add it +1 then you have the number of integers in the input) str = str.substr(1, str.length() - 2); // removes the { } unsigned int index = 0; char* ...Show All

• Visual Studio Team System Special icon for branch

  Hi, Currently, Folders and branches look the same in the IDE (like regular folders). 1. Is it possible to change the branch icon to a different one 2. Is it possible (in the future) to see a graphic window for the branches (like in ClearCase) Thanks, Michael Maybe. I'm not convinced this is a good idea. Should files that were created thru branching also have this icon instead of taking it from their file type Ok, so we apply your rule only to the root of a branch operation...except files can be branched directly too. Ok, so we special-case folders. Are we willing to make extra server round-trips when refres ...Show All

  I've been told by Kirk that it is possible to load a file whose metadata is unknown at design-time by using bulk insert along with a file (not a flat file) connection. He didn't elaborate though.

I used a foreach loop and a user variable to set the file name, the first table works fine but then it fails on the second because the column mappings are not being dynamically set in the dataflow task.
