• AdeptBlue ClickOnce Deployment Fails to Load Library after Impersonation

  I have an application that accesses a database that lives in a different Win2K3 domain. The application creates a windows Identity and authenticates the credentials and then does impersonation so that the database access happens in the context of this impersonated users credentials. Everything works great except the impersonation breaks clickOnce deployment. I am not totally sure exactly where or why but the app deploys and starts up but after the impersonation it tries to load an assembly and fails because the impersonated user does not have the necessary permissions. The application is running with Full Trust so I am not sure why it fails. If I install the application on the machine the old fashion way it works fine and if ...Show All

• LeoXue Editing Window Styles

  I'm working on a MDI program in C# and I need to change the way that the child windows look (ie changing the look of the border, minimize button, maximize button, etc). I've looked through a few books and done some searching online, but I haven't found anything on changing the look of a window. Is this possible Thanks! Well, i think you had to use SetWindowLong API with GWL_STYLE const int GWL_STYLE = -16; const uint WS_MAXIMIZEBOX = 0x00010000; const uint WS_MINIMIZEBOX = 0x00020000; uint style = (uint)GetWindowLong(this.Handle, GWL_STYLE); style &= ~(WS_MAXIMIZEBOX | WS_MINIMIZEBOX); SetWindowLong(this.Handle, GWL_STYLE, (int)style); const uint SWP_FRAMECHANGED = 0x0020; const uint SWP_NOSIZE = 0x0001; con ...Show All

• jam281 UserControl as Container

  Hi all, Just a quick question and I am sure there is a simple solution but I just haven't found it yet. I know how to make my UserControl a container by using ParentControlDesigner etc. This works fine and I can drag and drop Windows Forms Controls at design time. However, if I add a Panel to my UserControl Class, compile it and then try to drag and drop another control on the Panel, the Panel does not act as a container. So my question is: If I have a UserControl which consist of a single Panel, which is a pretty lame control I know, how can you get the Panel to act as a container at design time Any help in this would be greatly appreciated. Kind Regards AM PS. The UserControl that I have written does not consist of a ...Show All

• Sam Gentile MVP - Solutions Arch DataGridView Column Header Cell Style not working

  The backcolor for row header and column header does not work. e.g. Grid.Column(0).HeaderCell.Style.BackColor=Color.Blue Grid.Rows(0).HeaderCell.Style.BackColor=Color.Blue Grid.TopLeftHeaderCell.Style.BackColor=Color.Blue You could always just remove the theming on the headers. Set EnableHeadersVisualStyles to false and the header coloring will be honored. -mark Program Manager Microsoft This post is provided "as-is" Sorry you will have to draw the column or row headers yourself if you want to change the color. Paint in Column Header or Paint in Row header If we do so, then column sorting feature gets lost. The sorting arrow at corner of column header d ...Show All

• ks06 Minimum Height for Form?

  I can't seem to get a form of mine to draw at a height of 16 pixels. It always seems to add on an extra 16, I have FormBorderStyle set to None, not sure what's causing this A little weird that it wants to draw to 32...strange. No problems with a 1 pixel form here (VS2K5) Unfortuneately neither method worked, the form already set AutoSize to false, or not, as that is the default for a new form in vs2k5. The post seemed a bit odd, basically talking about putting the FormBOrderStyle declaration prior to the Font property, however I have no need for changing the default Font so it's not even defined. The way I'm working around the issue right now is just using a TransparencyKey, although that's a b ...Show All

• Peter Haik Get Rid of Warning Screen in Setup Program

  If I use the setup.exe that comes with the publish, a warning dialog comes up saying that "Publisher cannot be verified. Are you sure you want to install this application " Is there anyway I can get rid of that screen But Verisign costs money. So basically my only option is to live with it or ditch that installer and use NSIS or the VS deployment installer..., right If you clicked 'More information...', then you saw description of your colored shield icon and UAC's description for that item. Only way you to overcome the 'warning dialog' is disable the UAC alltogether, what I don't recommend. More UAC informations is in the Windows Vista: User Account Control Regards Peca Hey David.

• roy.wanglifeng BindingSource setting RowState.Modified on unchanged rows!

  I have a VB.Net 2.0 app with a readonly DataGridView and a BindingSource  and BindingNavigator which allows the user to edit, add and delete rows via my own custom controls (combobox, textbox etc). The table to edit is read in successfully then bound to (and displayed in) the DGV and I can do all the BindingNavigator stuff like editing fields from selected rows and adding/deleting rows as you'd expect. The problem I'm getting is that if I click on a row in the DGV but do not make any changes it is still marked as being changed (ie: RowState = Modified). I would have expected that only the rows that actually changed would have this status - otherwise what's the point So I guess my question is why is the BindingSource (or BindingNaviga ...Show All
