• Windows Forms Client App using IE Browser control

  I've been pulled into a project that is being developed for a device that will have no web server on it, but (for reasons beyond my control) the central part of the content is hosted within the IE browser control. I have been tasked with creating controls to be loaded within the browser.  I've been reading about how to host Windows Forms cont ...Show All

• Windows Forms .Net: Using VB to bind controls to a dataset row/column

  I am creating a VB form for which I use the control name to identify the table and column of a single row dataset. I bind the controls when the form is loaded and the data is correctly displayed as I expect.  However when I update the control (say a Textbox) the change is not reflected in the dataset.  This has been confirmed by stepping through the statements in debug mode.  I was wondering if I had missed something in my configuration or if there was an additional activity I need to perform to get the changed control property (Text) back to the recordset.  I have tried assigning a BindingManager but have had no success. ...Show All

• Windows Forms How to handle Ctrl-Drag on design surface?

  Hi, We've got a custom designer working, we can drag items from our toolbox onto the design surface without any problem. However, we want to handle dragging while holding down control - this should create a copy of the control. When ctrl-dragging, the icon changes to a + to indicate that this is what it's going to do, but on releasing the mouse, nothing happens! The MSDN magazine example from March 2006 has the same 'feature'. What do we have to do to enable the creation of the new control Many thanks, Gary Hi, A drag and ctrl-drag off the toolbox should be handled the same way. It doesn't really make sense to m ...Show All

• SQL Server SQL Low performance

  Dears, I am connection to SQL SERVER 2005 using an ODBC connection through ASP. I have a database with about 2 million records. When I run a huge query from a client all other clients can not work during mentioned huge query return results. Sometimes the time will goes far an all other connections will drop due to Time Out problem. Any suggestion Check indexes first. If you do a serach in a data or join tables and do not have proper indexes on a joined/searched fields, it will work very slow. Also check if your query locks records. If it does, it is also possible that other users will not be able to ...Show All

• Visual C++ Excel Chart in MFC Dialog

  I have been researching this for some time without much luck, so I am hoping to find someone to point me in the right direction! I have a program that displays outputs as graphs in MFC dialogs. Right now, I write the code to draw the graphs, but I think it would be much better if I could display it as an excel chart. I have found ways to automate Excel, but I don't want the user to need to have Excel running when they use my program. What I want is the user to begin my program. Select the dialog they want from a menu, and have that show the corresponding Excel chart in the MFC dialog. Any ideas Thanks in advance for your help! ...Show All

• Visual Studio Express Editions LNK1104: cannot open file 'c:\Program.obj'

  I am converting 3 different projects to C++ Express. Each time I started with "New" -> "Project" - after correcting my errors, setting Includes, adding Libraries, I always get the error LNK1104: cannot open file 'c:\Program.obj' Can anyone tell me what's causing this problem From what you said I take it you are not upgrading the project. Well, the only thing I can think of which is causing this is if you have c:\program.obj in the additional includes setting for the linker. One question though which may help answer this though, do you have a source file program.cpp o ...Show All

• Visual Studio Team System Checking in a "checkout" lock on a branch?

  Wow this strikes me as odd.  If I want to "lock" a branch, say a checkout lock, I then have to "checkin" that checkout lock.  That's a tad confusing.  I would have guessed that applying a lock was an immediate action like applying a label. I think we (if I may lump Keith in with myself) already do think of lock as a status on a file, which is exactly why showing a lock as a "pending checkin" is confusing. Every other SCC system I've used shows a "Status" column instead of a "Pending Change" column (current state versus future-state).  In the case of VSTF, you're showing the future state in ...Show All

• SQL Server Access Permissions on server scoped objects for login

  We are having problems with the response times from UPS WorldShip after switching from SQL Server 2000 to 2005. I think that the problem can be fixed from the database end by setting the permissions correctly for the user/role/schema that is being used by WorldShip to connect to the server but, I'm not sure how to do it.
