• Windows Forms TabControl - Disable/Enable tab page

  I have a tabcontrol with 2 pages. OnLoad the 2nd Tabpage shall be disabled (grayed out and not selectable). Later with code I need to enable the 2nd tab.

• Windows Forms Enable Typing of ComboBox in DGV

  Hi all, I read the FAQ doc but the suggested solution doesn't work for my case. I have a "data-bounded" combobox inside a DGV, and now I want to enable users to 'edit' the items of this combobox. Basically, the suggested solution is to: 1. change the DropDownStyle at run time 2. add a new item to the Items collection if the formatted value is not exist. However, my ComboBoxColumn is bounded by a DataSet (containing mutliple dataTable), so is there any workaround for this situation Thanks Hello Anyone know how to enable typing in ComboBoxColumn in DGV Am I hitting the blind spot of DGV :) ...Show All

• Visual Studio Team System TF30321: The name you typed is already used for another team project

  I had a project fail part way through creation (sharepoint timed out on creation for some reason) and it also failed to "back out" of creation properly.  Now when I try to create a project with that same name I get error TF30321 "TF30321: The name you typeed is already used for another team project on the Team Foundation Server.  Type a unique name for the new team project." I would have thought this was a big problem, but I had already successfully created a project and have since created another project so it seems to be some intermittent issue or timing problem.  I'll post up on the failure separately.  What I'm more c ...Show All

• Visual FoxPro Working Folder

  With VFP 3.0 I always checked whether the EXE folder sys(16,0) existed in the same folder as the current working folder set("default") + curdir() . If they did not match then I knew that CONFIG.FPW would not be read. So I would exit and display a message telling the user to modify their shortcut. Is there any way in VFP 6.0 and newer to make sure CONFIG.FPW is read regardless of the current folder or method used to start the program ================== I also used the following method to check if the EXE was already running. To prevent users from accidentally running the program twice and accessing the same set of data files. set libr ...Show All

• Windows Forms Centering column header text in DataGridView

  I'm trying to center the text in 2 column headers in a DataGridView. Can't find a way to do it in the designer, so I've written the following code to accomplish the task... deptDataGridViewTextBoxColumn.HeaderCell.Style.Alignment = DataGridViewContentAlignment .MiddleCenter; branchDataGridViewTextBoxColumn.HeaderCell.Style.Alignment = DataGridViewContentAlignment .MiddleCenter; This *almost* works.

• .NET Development Concurrency Violation When Updating MS Access Db

  I am working on a VB .Net 2005 application with a MS Access database backend. I am able to add a new row to a datatable via a DataGridView control. After invoking the Update method on the TableAdapter, I have verified the new row is written to the Access database with the values I've entered. This problem is I get a concurrency violation error when attempting to save (update) a subsequent edit of the newly added row. I am the only person making edits to this database. This row does contain an autonumber field. Making the TableAdapter.Fill call again to refresh the datatable after initially adding the row corrects the problem, but seems inef ...Show All
