• Visual C++ Is partial redistribution of VS 2005 DLLs allowed?

  We're looking at migrating our applications from Visual C++ 6 to Visual Studio 2005.  We link in the MFC and the C-runtime DLLs.  Since users download our application over the Internet, we need to minimize the download size as much as possible.  We would need to redistribute the VS 2005 DLLs as applocal. Does the license agreement for redistribution require that the entire contents of the Microsoft.VC80.CRT and Microsoft.VC80.MFC be redistributed if any of them are needed Or would it be possible to just redistribute mfvcr80.dll and mfc80.dll and their manifests appropriately modified, since that's all we need at this po ...Show All

• SQL Server SSRS 2005 XML datasource & report subscription question

  I'm working to enable subscriptions on some reports that have an active directory web service as a datasource as well as a standard datasource to a SQL server db. I'm admittedly new to reporting services '05, but some research tells me I can't do the job with the current configuration. As the AD web service is an XML datasource, I'm not sure if I can pass an expression...and the reporting service manager won't let me store the credentials on the server...please help! I'll rebuild these things if I have to -- I just need some direction on how to build the reports so a subscription is possible and the data is specific to the user requestin ...Show All

• Visual C# Database Question

  Hell All, I am creating a program that will be used by about 20 people or so. It is a test case managment system, what I want to do is have everyone connect to a central database on a server somewhere on the network and be able to edit , update, create, save test cases. What I am unsure of is, do I need to write software on the database server to handle transaction, etc, or can i just connect to the database from the program on the users desktops, and load the data both ways from there. I am new to database programming. Also is there a way to write generic database commands, so any database, like MySQL, PostgreSQL, Oracle can be used on the ...Show All

• SQL Server Querying Oracle v8.1.7 with multivalue parameters

  I am currently working towards an Oracle server through Microsoft SQL Server Reporting Services (2005) and I am troubling with an "ORA-12704: character set mismatch" error when I generate my reports.

The following query illustrates the problems I'm having: select * from table x where x.date between :startDat ...Show All

• Windows Forms Problems databinding a combobox

  Hi, I have a winforms app that binds it's fields at runtime to a dataset.  Basically if the combobox/textbox name matches the field name, it is bound. Here's the code that does the binding.. oBinding = New Binding("SelectedValue", dsToBindTo.Tables(TableName), ctl.Name.ToUpper) cmb.DataBindings.Add(oBinding) Pretty straight-forward eh   BUT, when I run this code, the comboboxes stay on the first row in the dropdown, rather than reflecting what is stored in the database!! What am I doing wrong G Did you set the ValueMember for the ComboBox   If not, you need to in order for this to work ...Show All

• Visual C# "Enter outlining mode when files open" Does not work in Visual Studio 2005

• Smart Device Development CameraCaptureDialog Issues

  I've been having some issues using the CameraCaptureDialog class on an HTC Apache device (rebranded as the UTstarcom 6700): 1. After exiting my application, the device's camera capture screen comes into focus. This happens whether I dispose of the class instance or not, and the Close() method is protected, so I can't call that. Any ideas on getting rid of this lingering capture screen 2. On a seemingly random, intermittent basis, an InvalidOperationException will be thrown from within the ShowDialog() method. Sometimes this will happen after taking 4 or 5 photos, but other times it will work fine for 40 or 50 photos before I give up trying ...Show All
