Andrew Connell4-Jun-02 2:16 Andrew Connell 4-Jun-02 2:16  I'll start with saying that it's somewhat difficult explaining exactly what I am having trouble with, so bear with me.. My application loads an initial form (MainContainer). This form, uses another class file (PAMenu) within the project to build & return an object containing a control menu. The PAMenu contains all of the menu construction, changes, and event handlers. It uses a 3rd party control (MagicLibrary) to build the menu (giving it the OfficeXP/VS.NET menu appearance). My problem is that I am having trouble accessing methods & properties in the MainContainer form from the event handlers. Here's a bit of code: [MainContainer] private PAMenu thePAMenu = new PAMenu(); appMenu = thePAMenu.Menu(); // builds the menu with default settings & display settings Controls.Add(appMenu); [PAMenu] //this simply builds the menu and contains event handlers //the internal menu object is called 'theTopMenu' [MagicLibrary] //this control overloads the MenuControl and MenuCommand objects I have no problem handling events if they don't interact with the MainContainer or it's child forms (such as the Exit handler running Application.Exit()), but calling a public method within MainContainer just isn't working. I've tried the following from within an event handler in PAMenu: this.theTopMenu.ParentForm which gave me access to the default properties of the MainContainer form (I was able to change the text in the titlebar), but I can't see my exposed methods. The odd thing is that I can see some of the private properties when stepping through intellisense. Any ideas?

Thanks for any suggestion. Re: Emergency!! Can I use SDK in win32 project ? Paul M Watt3-Jun-02 11:54 Paul M Watt 3-Jun-02 11:54  you need to make sure that your project is linking with this library, LIBCMT.LIB.

How to make a hyperlink column in datagrid in Winforms? 3-Jun-02 9:19 3-Jun-02 9:19  Anyone knows how to show a column in a bound datagrid as a linkLabel(hyperlink feature), when click it, can nevigate to somewhere? Thanks a lot. Reading/Writing to *.INI files tigre2153-Jun-02 8:23 tigre215 3-Jun-02 8:23  I'm creating an appliation that reads/writes from/to files that have the same structure as an INI file. Win32 includes a few methods to read/write keys, section, etc. I've tried to do this using C# but it could not compile. It inidcated that the methods I was using (e.g. GetPrivateProfileInt...)were not recognized or not included in any of the namespaces. Does C# support the use of these functions? If so, under what namespace?

DataGrid problem Alexandru Savescu3-Jun-02 6:25 Alexandru Savescu 3-Jun-02 6:25  Hello, This is my first C# project so you might find this question stupid I have created a windows application and dropped on the form a sqlConnection and a sqlDataAdapter that uses the sqlConnection to connect to the database. From the sqlDataAdapter (that maps to a specific table) I have created a DataSet via the wizard. Now I dropped a DataGrid on the form and set its DataSource and DataTable memebers correctly (I think at least, because I can see the column headers created from the dataset, and from the SQLDataAdapter I can preview my data correctly). Then in the constructor of my form I did sqlDataAdapter1.Fill (dataSet11); When I compile and run the app the datagid shows nothing but one single row and in the cells it says "(null)". What do I do? Best regards, Alexandru Savescu Re: DataGrid problem Mazdak3-Jun-02 6:36 Mazdak 3-Jun-02 6:36  I'm not sure,but have you try other versions of Fill(),add the the name of table you want with start row and end row,also are you sure that your table is not null?

Re: how can i output debug info like "TRACE" in C#? Rocky Moore3-Jun-02 18:35 Rocky Moore 3-Jun-02 18:35  In Dev7 you can also use System.Console.Write and System.Console.Write to write to your output window. Tip# If you do not like all the long names you can put a shortcut 'using' line in the header like: using db=System.Console later use: db.WriteLine Rocky Moore NDoc Joshua Nussbaum2-Jun-02 21:21 Joshua Nussbaum 2-Jun-02 21:21  Check out this link.
