• Visual C# Global Hooks and .NET dll / Assembly

  Hello, I want to write a program which detects and monitors other running/starting/stopping programs. To do so I know I need a global windows hook. To install a global hook I need to load a dll, which is mentioned as a normal dll and not a .NET dll (I've read there's a difference, but I don't know what exactly). So I'm wondering is whether this will work when writing a .NET dll / assembly and loading that one and, if possible, how to do it. I'm new to .NET and C#, so any help would be appreciated on this matter. Alexander For (most) global hooks, you need to use unmanaged code becau ...Show All

• Windows Forms DataGridView vs DataGrid bound to DataView

  I have DataView containing a DataSet with a relation defined between 2 tables. When I bind the DataView to the DataGrid, the grid displays both parent and child tables just fine. But when I gind the DataView to the DataGridView, the grid only displays the first table. Any thoughts out there ----------code snippet---------------- -- Fill tables, set relation, fill data view -------------------- String sql1 = "Select * from user_def order by login_id" ; String sql2 = "Select * from user_app_auth order by login_id, env_id, app_name" ; String table1 = "user_def" ; String table2 = "user_app_auth" ; String relationName = "u ...Show All

• Smart Device Development Free memory in compact frame work 1.0

  Hi all, I'm writting a Point of Sales application for use on a PDA device, when I move from one screen to the next I use the me.Close() to close the previous screen(form) and then load the next screen. This is working fine, however when I go can check the running programs on the PDA device, it displays a list of all the forms I've entered, even the ones I've closed. This slowly slowly eats away at the available memory I have free on the PDA. By using the me.Close() shouldn't all closed forms be removed and memory released Whats the work around for this Thanks Coss Hi Kolya, Thanks that works nice. ...Show All

• SQL Server sql_variant in Data Flow Task

  When I add a OLE DB Source that accesses a table that contains a column of data type sql_variant, it generates an error message saying that is an unsupported external data type and will be converted to DT_WSTR.  Since there are large values of the float data type, I am concerned that the float values would be truncated. The only way I have been able to work with sql_variant data types where two databases are involved (source and target of an insert) is using an Execute DTS 2000 Parckage Task.  I tried using an Execute SQL Task and got the same message as above.  Note that when I access the sql_variant column in an Ex ...Show All

• Visual Basic Calling API with "void *"

• Visual Studio Express Editions Accessing Controls in a different Form.

  Hi there. I'm new to C# and programming in general and need some help on my first "project". I'm writing a very basic program. It uses the built in WebBrowser control and the TabControl-control (phew). Each tabpage got a different webbrowser control in it. There is no problem when i add all the controls from the Form1 designer. The problem is when I try to dynamicly add TabPages, and a webcontrol in the created tabpage. I'm opening a new form with the "ShowDialog()" method. I have a listbox and a button in this new form. The idea is that the user(me) can select what TabPage to add to the tabcontrol using names with prede ...Show All

It fails when you run the test. In loadrunner it also does not show up but it passes when you run the test. Any help would be much appreciated. ...Show All

• Visual Studio Express Editions Problem building MediaShare Messenger Starter Kit

  Hi all, When I try to build MediaShare Messenger, the build process stops with this error: .\app.rc(10) : fatal error RC1015: cannot open include file 'afxres.h'. Indeed, this file doesn't even exist on my hard drive, so I guess it wasn't included with ISO image from which I installed VC++. That's strange, because MediaShare Messenger is listed as a starter kit for VC++ 2005 Express Edition , so I was sure it would compile without problem. Any ideas Thanks in advance. MFC development is not supported under the VC++ Express Edition. For ATL/MFC applications, higher versions of VC++ should be use ...Show All
