• Windows Forms EndEdit: leaving edit mode in a datagridview

  Hi all, i'm using a DataGridView containing a ComboBoxColumn. The DataGridView is not bound to any data source and it gets populated through an ArrayList "manually". The VirtualMode is not activated and the EditMode is set to EditOnEnter. I'd like to end or leave the edit-mode of a cell in the ComboBoxColumn programmatically after selection-changes in the ComboBox has been committed. Therefore i handle the EditingControlShowing-Event of the DataGridView and the SelectionChangeCommitted-Event of the Combobox. As you can see below i call EndEdit() in the ComboBox_SelectionChangeCommitted-Methode. private void dgView_EditingControlShowing( object sender, DataGridViewEditingControlShowingEventArgs e) { ...Show All

• Smart Device Development C++ in PDA development

• Visual Basic Form object resizing

  Hi there everyone, Something is baffling me here.  I'm trying to code a resize event to ensure correct placement of my controls whenever the form is resized.  I have a picturebox control that I wish to fill the screen but leaving a gap, of around 3, either side.  At the bottom of the form I have a textbox control (txtCallsign) that I intend to keep fixed to the bottom of the form.  I've tried the following code: Private Sub frmMain_Resize( ByVal sender As Object , ByVal e As System.EventArgs) Handles Me .Resize ' Resize the picture box control as the form ' resizes. PictureBox1.Left = 3 PictureBox1.Top = MenuStrip.Height + 1 PictureBox1.Width = Me .Width - 6 PictureBox1.Height ...Show All

• SQL Server Put select statement in SSIS variable

  Is it possible to add a variable in SSIS like name of variable: myVar Scope: Data Flow Task Data Type: String Value:SELECT hello FROM blah WHERE (azerty = @[User::pda]) AND (qwerty = @[User::phone]) @[User::pda] and @[User::phone] are also variables in SSIS just like the myVar I made I know I'm doing something wrong with the data type because it's stores the whole select statement as a string Help Worf Worf, Are you using an expression in myvar variable to get the query I guess you are trying to build the query dynamically; if so then few things: OLE db command and OLE DB source only accepts SQL syntax; so +@[user::pda ] + won’t work there.

• SQL Server SessionTrace during XMLA execution?

  Hi all! I wrote a command line tool that processes a SSAS cube/dimension. At the moment the tool starts processing similar to: using Microsoft.AnalysisServices; olapsrv = new Server(); olapsrv.Connect(@"SERVER/DATABASE"); Database mydb = olapsrv.Databases["NAME"]; Cube mycube = mydb.Cubes.FindByName("CUBENAME"); mycube.Process(ProcessType.ProcessFull); it is possible to trace the server output with: olapsrv.SessionTrace.OnEvent += new TraceEventHandler(DefaultTrace_OnEvent); olapsrv.SessionTrace.Stopped += new TraceStoppedEventHandler(DefaultTrace_Stopped); olapsrv.SessionTrace.Start(); the two functions can write the "feedback" to a ...Show All

• Visual Studio Team System AssemblyInfoTask default Versioning Flawed?

  Is it just me, or isn't the notion of versioning defaulted to by the AssemblyInfoTask http://www.gotdotnet.com/codegallery/releases/viewuploads.aspx id=93d23e13-c653-4815-9e79-16107919f93e  fundamentally flawed. Assuming major.max.build.revision. Everyone using this task, including Microsoft, seems to be using the strategy that the build number is specified to be DateString with a format of yymmdd, you get something like 061117 on the day of this post or the following if we accept the defaults: 1.0.061117.00 First of all, the actual number (since it gets converted to an integer) becomes 1.0.61117.0 when it gets compiled.  Most importantly, if this was next year (2007) at this time, you get assemblyinfo files u ...Show All

• Windows Forms Center label on maximized form and wordwrap text

  Should be fairly simple but because today is Monday I can't seem to see it.... My form is borderless and maximized. I have a single label that I would like to be horiz and vertically centered on the form. I'd like the text in the label to wordwrap and not go off the screen. Can someone please help me with this Thanks ! Set the label's AutoSize property to False. To get its text vertically centered in the form, independent of the amount of text it displays, you'll need to measure the vertical size of the displayed text. Check this thread for code. ...Show All
