• kennm How to map a CellSet

  Hi, I'm using Analysis Services 2005 and VS2005. I have to display a CellSet (the result of a MDX query) on a form. There is a grid object to map a CellSet I tryed the DataGridView control, but it seem more suitable for standard SQL DataTables. Thanks in advance Marco Windows Forms doesn't have any built in controls to use with Analysis Service.

• Sean McElroy Datagridview in a groupbox

  Hi all, I have a problem adding a datagridview control in a group box. I am trying to add a datagridview and 2 other buttons inside a groupbox. I want the 2 buttons at the top and then the datagridview below the 2 buttons. I have them set in the design mode this way, but when I run my app and see this form with the group box, the screen shows the datagridview covering the entire the group box and the 2 buttons are hidden behind the datagridview. Also, if I resize my grid to a smaller size at design time, at run time the behaviour again changes and I see the datagridview covering the entire group box. Is there any setting which am missing here to make sure that the grid doesn't cover the whole group box any suggestions would be greatly ap ...Show All

• cadouthat printpreviewcontrol

  The people at microsoft are strange aren't they I have just started work on something where I'm using the printpreviewcontrol for the first time and I was looking for the method that would cause the control to refresh it's contents, after the page settings of the document had been changed. Foolishly I had some expectation that it might be called refresh but no; apparently on this control you have to call invalidatePreview.

• Michael J Brown Error 2203 when installing MSI packages I created with VS2003 - just problems with my profile

  Hi Suddenly, my MSI packags have stopped working. The packages I create all fail with error " The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2203 ". This happens for packages for existing solutions, and also for any new package I create from scratch. There I assume it must be a generic problem with the installer or VS, rather than a problem installing one particular program. It happened when I made some changes to souce of a project, re-built the package. Note that the packages run fine on other people's computers. Note also that it runs fine on other profiles on my machine - thus it might be a problem with my profile o ...Show All

• SLang FlowLayoutPanel FlowDirection not working when adding controls at runtime

  I have a FlowLayout panel to which I am adding a label and linkview controls at runtime. The panel's FlowDirection property is set to TopDown. However, when I call Controls.Add on the panel at runtime, the controls are still added left to right. Why does this happen If I drag controls onto the panel at design-time, they are added top to bottom as required, it's only when adding at runtime that this happens. That worked for me, thanks!
