• Visual Basic VB 2005 Express upgrade from VB6

  I cannot upgrade a VB6 project in VB 2005 Express. The upgrade wizard opens and at the point where upgrading starts it thows and exception: "Unexpected exception occurred during upgrade engine operation: Not able to bind to the source (Exception from HRESULT: 0x8004000A (OLE_E_CANT_BINDTOSOURCE))" I tried the upgrade wizard on a simple VB6 project that contains 1 form with 1 command button on and the same message comes up. The VB6 and the upgrade folder are both on C: I can't find any reference to this error message anywhere in the Knowledge Base or MSDN sites Chris I have uninstal ...Show All

• .NET Development SetDataBinding replacement in dataGrid

  In translating/migrating some c++ pro 1.1 code to 2.0 c++ express, I get an error that SetDataBinding' : is not a member of 'System::Windows::Forms::DataGridView and wondered what is the equivalent to datagrid0->SetDataBinding(dataSet0,"tbl0"); in a DataGridView Thanks. The only reason I took such a way was I could not get the data source to configure with wizard, but that seemed to go away after a reboot and not opening a project that had manually written connections. Probably my data controls will add with the wizard now that the data source has been set up. ...Show All

• Visual C++ Can I do this?

  Can I download Visual C# Express Beta 2 after I've downloaded Visual C++ Express Beta 2. I'm using C++ right now, I just don't know if it will work correctly with BOTH of them on my computer at the same time. Visual C# Express and Visual C++ Express can be installed both but only if they are the same version (both beta 2 or both final version). So if you have a beta 2 version installed you must uninstall it first then download the final version of this products (I don't think that you can still download a beta 2 version anymore since there is a final version available). ...Show All

• .NET Development Database login window popup

  Hi, there, I'm getting a problem when generating crystal report in .net. There is always a popup window called " Database login", asking input for ServerName, Database, LoginId and password. And whatever login id and password I've enterred, It gives me the error message "Logon Failed. Please try again." I've checked the SQL Server Enterprise Manager, the permission of the table I'm accessing has been setted up to public access. It doesn't seem like the problem. So, any advice Thanks in advance. yaduo What is the datasource of your report If it is a dataset with more than one datatable, and you are binding directly to the dataset, ...Show All

• Visual Studio Express Editions Can't Download .NET Framework 2 and VB Express

  I've downloaded the setup file and can run it. It's reached the point where it says it is downloading 60MB of stuff comprising .NET Framework 2.0 and VB 2005 Express Edition but it just sits there with a transfer rate of 0KB/sec. Went to the troubleshooting guide and tried a few things that did not work (the BITS stuff which required Genuine Window checking which did not work - says it is no longer supported or something like that - after downloading the GenuineCheck.exe). Oh yes, I've tried rebooting the PC and tried running setup again at least 6 times without success. I'm feeling lost and a bit disillusioned by the initial " ...Show All

• .NET Development Web service not responding sometimes

  I am using a webservice to invoke a lengthy process in server. But I am not getting response back to the client always. The process will take around 40 min and the last task is to send an email and log the response. It does all the task including logging the response.
