• Windows Forms Looping through combo box display members

  Dear All, My problem is related to combo box. I have managed to bind values from a select statement from a database to combo box successfully with cbBox1.DisplayMember = "ID" ; cbBox1.ValueMember = "valueText" ; The problem comes when I run for ( int j = 0; j < cbBox1.Items.Count ; j++) { MessageBox .Show (cbBox1.DisplayMember[j]); } When I run through the loop I dont get the exact value of the DisplayMemberbut just one character from the DisplayMember. How can i show the whole text rather than then just a particular character. Thanks. The display member is just a string that tells the combobox what field to get the text from in the datasou ...Show All

• SQL Server reference member in user hierarchy

  hi, I have a user hierarchy in my Date Dimension such as [Calendar]->[Years]->[Quarters] And I can access the member by directly call the memeber name, for example: select [Date].[Calendar].[Years].[2006].[Q2] on columns, ...................................

• Visual Studio Team System Performance Problem #2

  We've got a project with 3200 objects. The project contains about 10 errors. When we attempt to double-click on one of the errors to bring up the file, Visual Studio will hang for anywhere between 3 and 10 minutes. The Task Manager shows 'devenv.exe' consuming about 90% of CPU resources for this entire time. We're using the RTM version of DBPro. Amos. Gert, You asked me if I tried these operations while not under source control. I now have. Just to reiterate, we have the following major performance problem areas in our 3200 object project which is under TFS source control: Opening the project, after the first time, can take anywhere between 3 and 20 minutes.

• Visual Studio Team System help understanding relationships between TfsWarehouse tables

  I've been tasked with generating a couple of reports for our QA leads. They have created several test categories and each category has multiple test cases (i.e. a basic one-to-many). Basically they want a report where each row is a test category and has the following data fields associated with it: number of test cases written for this category number of test cases executed number of test cases that passed number of test cases that failed number of severity 1 bugs related to this test category number of severity 2 bugs related to this test category number of severity 3 bugs related to this test category So the layout would be something like: Customer Data Entry -- 15 test cases written -- 7 executed -- 3 passed -- 4 failed -- 3 Sev1 Bugs ...Show All

• Visual Studio Team System sotre.query gives more columns then specified in SELECT

  Hi, I'm new to TFS and trying to get all work items for a project in a gridview in asp.net. My code: query = "SELECT [System.Id], [System.Title], [System.AssignedTo], [System.CreatedDate], [System.CreatedBy], [System.State], [Microsoft.VSTS.Common.Severity] FROM WorkItems WHERE [System.TeamProject] = @project ORDER BY [System.Id]"; return store.Query(query, parameters); when I put the resulting workitemcollection as datasource in a datagridview I get 27 columns instead of the 7 I've specified in the select. Funny thing is that I do get different results (less rows) when I adjust the where statement but even if I select just 1 field (System.Title for example) I get 27 columns.

• Internet Explorer Development IE7 RC1 window.close() issue

  We have a web application that we are currently testing with IE7 RC1 in order to be ready for the release of IE7. We often open new browser windows using script (i.e. window.open()) but have found that whenever we attempt to close the child window using script (i.e. window.close()) we are prompted with the message "The webpage you are viewing is trying to close the tab. Do you want to close this tab " We do not have this issue with IE6 and have not yet been able to track down the reason for the issue in IE7 RC1. I understand that you cannot close a browser window through script that has not been opened with script. But in our case, we are opening the child window with script.

• Windows Forms Problems with PrintPreviewDialog

  I have the following code: try { printPreviewDialog.ShowDialog(); } catch (InvalidPrinterException e) { MessageBox.Show(e.Message); } When it runs on computer where no printers installed, I get error message as expected. But when user selects the same function second time, the following exception is shown: System.InvalidOperationException: Form that is already displayed modally cannot be displayed as a modal dialog box. Close the form before calling showDialog. printPreviewDialog is the same instance as in first call.

But I want to know right way to do this - how to cancel running dialog, which is still active, ...Show All

• Visual FoxPro Excel to cursor SPT problems

Dave's code is a subset of what I've posted and I think I have posted it before (not sure). If it's coming during SQLExec() makes more sense, because as I said before you shouldn't trust all tables in Excel are named "Sheet1$". For example: use customer copy to mycustomer.xls type xl5 Open the xls in Excel and chec ...Show All

• SQL Server Bulk Insert fails to import data files created on Unix

  It seems to me that files created on Unix machines with line terminator \n, or chr(10), cannot be imported using the Bulk Insert statement. Is this a bug, or an oversight by Microsoft Does this mean that unless one replaces all \n with \r\n, there is no way to use Bulk Insert to import Unix files This is a very strange behavior by MSSQL. Even lessor programs such as Excel and Word automatically recognize chr(10) as a line termination character. Am I missing something, or is this just the way MSSQL is I have never succeeded to convince BULK INSERT to read Unix files, and I find one of these solutions usually works: 1. See if the process that moved the files from the Unix machine can correct the line ends (for example, ftp can ...Show All
