• Windows Forms Opening / Closing Forms

  Hey guys, Really simply, how do you open forms when you click a button! ! (i.e. in VB its docmd.open 'Form'). I just want to click a button and it pop up another form i have designed. Thanks in advance Tom Well, you create an instance of your form and display it using ShowDialog(): Form1 form = new Form1(); form.ShowDialog(this); (The parameter to ShowDialog() is made the parent of the form which is displayed. Since you will be calling this code from a button handler in the parent form, "this" is the correct thing to pass in.) ...Show All

• Windows Forms Help on PropertyGrid

  Hi there! Is there another way of setting the properties in a PropertyGrid besides using propertyGrid.SelectedObject or propertyGrid.SelectedObjects I would like to load the properties without having the PropertyGrid read them from myObject. For example, is there a way of doing something like: propertyGrid.SetProperties (collectionOfProperties) or anything similar to that I think I have found the exact answer I'm looking for on a different post http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=480921&SiteID=1 ...Show All

• Visual Studio Express Editions How do I

  Hi, How do I get a form that I have designed to do the following: Take the data from 5 seperate input boxes (5 seperate text boxes used for input) and output the largest and smallest number to seperate output boxes (2 seperate labels used for output). If the user inputs a number in each box for example 25, 15, 75, 45 and 67 and then clicks my button "Find" I want the largest number to go in the largest output label and I want the smallest of them to go in the smallest output label. How do I code my button to take these 5 input numbers regardless of their order and output only the largest and the smallest of the group of numbers I hope someone understands what I am asking. Thanks, DC     Act ...Show All

• .NET Development Exception: DataTable internal index is corrupted: '5'. on ...

  Hi, I have a problem with bindingsource component in framework 2.0. I have a combobox bound to a bindingsource which is also bound to a dataset with 2 related tables and a datagridview bound to the same bindingsource. What I want to do is : When the selectedindex property of my combobox changes, the corresponding cell value must be changed in the datagridview. But although the value in bindingsource changes, datagridview does not display the new value. That value is displayed after I move the mouse over that cell and make it invalidate its region manually. Another error I caught is the one that you can see as the subject of my post. I do not know why i have that message when I try to change the property of ((DataRowView)mybindi ...Show All

• Visual Studio 2008 (Pre-release) Beginners Information

  HI, I'm looking at trying to use WCF for a fairly large project that i need to undertake. Basically we have a Handheld ( CF 2.0), web site and a couple of other applications that all need to share data between each other, data is stored in SQL 2005, currently our HH talks to an application on the server via TCP. The web uses Web Services and the other apps might use MSMQ or something else, essentially the HH sends pre determined messages to the interface with then updates the DB. The entire system needs to be rewritten, and im focusing on the main server/interface app that everything talks to. WCF seems to be a modern way to approach this. But i have a few questions. Based on my description above is WCF the right platform. The HH ...Show All

• SQL Server Truncation error when importing from ODBC to flat file

  I am having problems reading from and ODBC conncetion from Oracle RDB into SSIS. I am using a DataReader source which uses a ADO.NET odbc connection to an oracle RDB database. I am having that write to a flat file. When I read integers from the source, it works just fine. When I read character data (char(48) for example), it gives me trucation errors.

• Game Technologies: DirectX, XNA, XACT, etc. Performance Questions

  I have two questions regarding how much of a hit certain practices might take to the speed of the game and if anyone has taken the time to run the system through its paces yet. 1) How badly does using accessors (private members with public get and sets pointing to them) tax the system. I can't imagine it being a whole lot, but I can see if you have enough classes in use at the same time, it would add up. In my other, non-gaming, applications (both web and window) I make a strong practice out of never exposing members to the outside world unless it is done via a property, but I noticed that the SpaceWars demo either doesn't do that at all or does it very infrequently. I also remember the GarageGames guys at GameFest, I believe it was the ...Show All
