• Visual Basic Please Help me in converting VB6 DataGrid usage to VB2005 DataGridView.

  Hi, I am a newbie VB6 programmer looking for assistance in converting the following code into VB2005 code. No matter what I seem to do I cannot get an equivalent that will run using VB2005.

• .NET Development Trouble catching exception

  Hi, I am having this problem catching a exception in a try catch block as shown below try { DialogResult result; result = wizard.ShowDialog(); } catch (PackageCreationException e) { MessageBox.Show(e.Message, "Failed", MessageBoxButtons.OK, MessageBoxIcon.Warning); } now the wizard is a form which throws a PackageCreationException if it fails this works fine if it is run in the Visual Studio environment but when run as a standalone application this exception is not caught. I have been cracking my head over this. I can catch and handle exceptions fine every where else but here. Does anyone know why this happens ...Show All

• Visual C++ Intellisense becoming unable to resolve objects

  I'm posting this here and not in the general Visual Studio forum because my experience so far tells me the situation with C++ is different than with, say, C# (I have so far at least one example where VS's tools behave worse in the C++ environment than in that of C#). I have Intellisense getting confused and unable to resolve objects so often that I find myself closing the solution, deleting the *.ncb file, and reopening the solution. It almost makes me wish I had a "rebuild Intellisense" button...

May be they will be able to shed more details. Thanks, Ayman S ...Show All

• Visual Basic Estimating a process finish time

  Hello, I have experience of VBA and I am developing my first app in VB within VS2005.  The app will have to process hundreds of files on a frequent basis and import them into a SQL Server database.  The user will select lots of files and then walk away from the machine.  I want to be able to estimate the finish time so that they can watch progress and manage their time. In VBA it is simple as the type date can be used in functions so the equation dtFinish = dtStart + (Now() - dtStart) * lngFilesToProcess / lngFilesProcessed would yield a date with the estimated finish time. A similar approach in VB does not work as I get IDE errors in my code telling me I can not * a date and an integer. I have looked at th ...Show All

• Windows Forms DataGridView - Replace column with my DateTimePickerColumn

  Hi I have a database with one table containing: - id (int) - name (string) - date (DateTime) Now I fill a DataSet with the data in the database using OleDbDataAdapter . Then I connect the DataTable (inside the DataSet) to my DataGridView: - datagrid.DataSource = dataset.Tables[0]; I then created a DateTimePickerColumn (inherits from DataGridViewColumn ). (The control works fine) Now to my question. How do I replace the "date" column to be a DateTimePickerColumn Do I have to: 1. Hide the "date" column. 2. Add a new column (DateTimePickerColumn) 3. Implement code for copying data between 1. and 2. I want DataSet.Update() to work with DateTimePickerColumn . Anyone :) / K ...Show All

• SQL Server #Error using IIF and divide by zero

  I am getting an error in a calculated field that could potentially divide by zero, even though I'm using an IIF. The column displays in the report as "#Error". My expression looks like this: = IIF(Fields!Qty.Value = 0, "None" , Fields!Hours.Value / Fields!Qty.Value) I have successfully used this approach with INT fields, but this time the Hours field is a NUMERIC(9,2). My workaround is to do this: IIF(Fields!Qty.Value = 0, "None" , IIF(Fields!Qty.Value = 0, 42, Fields!Hours.Value) / Fields!Qty.Value) I guess the 42 is cast to an INT inside the second IIF and the calculation works. What's strange is that the division would even be carried out in the event of Qty = 0 from the first II ...Show All

• Architecture Windows Installer -> How to make patch or upgrade

  Hi to all, I'm reading "The Definitive Guide to Windows Installer" to make upgrade or patch to my app. But all the procedure explained in the book is too much expensive for a programmer, and manual edit ORCA db is not a friendly procedure.

However, can i have some suggestion to other good installer for installation packages building I could point at these tools: Macrovision's Installshield Wise for Windows Installer WiX - it is powerful tool but it is not easy to use as there is no sophisticated UI VS 7.0 and 8.0 - you can use Setup Project template ...Show All

• Software Development for Windows Vista De-normalization required for querying WorkFlow Instance Status

  Hello all. I have been experimenting with WWF and find the UI based definition of work flow incredible. I worked primarily with the State Machine but found a limitation as far as my implementation was concerned. Basically, I need to display the State for 10,000-40,000 items in a view. To do this I had to duplicate the status in another table due to the fact that the default persistence model stores the Work flow instance as a blob. Was wondering if anyone had similar requirements and had less redundant solutions. It sounds to me like a better way would be to write your own custom Tracking service (note: tracking, not persistence) that tracks the state changes in your workflows in a way that gives you easy access to the ...Show All
