• Visual FoxPro Grid and textbox Refresh issue.

  I'm having this problem with an application I’m writing. I have a Grid with a couple of text boxes next to it. When you select a record it updates the values in the textboxes with the values from that record. I also have a few command buttons that switch the tables viewed in the grid. Now here’s my problem... The text boxes stop updating after I change the tables a few times. Not sure what I am missing because I don't get any error messages and it does work for a little while. If you need more information let me know. You need to use a safe select method to change data in a grid on the fly. See www.tightlinecomputers.com they have a complete listing of what this entails. ...Show All

• Visual C++ Calling MS Access VBA code

  I would like my C++/CLI (vs2005) app to invoke a couple of functions on a MS Access 97 database. These functions are implemented in VBA. Is it possible If so, please provide me with starting points and links. If not, what are my options If you have a question about the VC language, then this is the place to ask it. The VC language alone however has no capability for accessing an Access database; you must use libraries that VS does not provide. Therefore you need to ask in another forum or in an appropriate newsgroup. I can suggest however that you look at the command-line options for Access. I don't know if there is an option for executing macros but if so then that might help. Otherwise, ...Show All

• Visual Studio Busted WindowsEvents in 2003

  I created a 2003 C# Visual Studio add-in, and added the following code to the Connect.cs. I get approximately *two* calls to the onWindowEvent function and then complete silence. Does anyone else have this issue I thought I might be nerfing events in my package, but I've tried this in the regular registry root (i.e. not 7.1Exp ) and the problem still occurs.

• Visual Basic Slow Timer

  Hi, I've written a program that uses a timer to control an external relay (via USB) that turns on a light. The problem I'm having is that the timer is slow (about 4 seconds per minute) on my desktop computer, but its timing perfectly on my laptop computer. I've retested this on other computers and I get a similar result. Is there a way to ensure that the timer is right on everytime Its also worth noting that the clocks on all these computers are keeping the correct time. Thanks, P Here is the relevant code, thanks for your help.

• .NET Development .NET 1.1 vs .NET 2.0 behaviour with Image fields

  In not .NET 1.1 and 2.0 the System.Type mapping for a SqlDbType of Image is byte[]. If you use this type to create a SqlParameter (with a value of DBNull.Value) and then use this in a SQL statement of the form "Update table Set ImageField = @parm where ......" Then in .NET 1.1 it works, but in 2.0 you get an Exception "nvarchar is incompatible with image" How can you determine the correct System.Type to use for Image fields, and why is the behaviour now different The application code is generic and not tied to specific database designs. Thanks Tony im not entirely sure about that one to be honest. I'm actually a bit confused on what you are trying to do - ...Show All

• Software Development for Windows Vista directshow filter : splitter

  Hi, When I want to run a mp3 file, could you tell me what is doing the mpeg 1 splitter As The mpeg1 splitter splits an MPEG-1 system stream into its component audio and video streams and I have only audio. Thanks a lot The source filter is pull-mode and the rest of the graph is push-mode, so you need a filter to convert between the two. Typically this filter will also do the seeking and timestamping of samples. So you will often get a demultiplexor in the graph to do these tasks even if there is no actual demultiplexing to do.

• Visual Studio 2008 (Pre-release) Client Callback Address, wsDualHttpBinding and Windows Security

  Hi, Are there any chances that on the client side wsDualHttpBinding works without starting the client process under a windows administrator account We tried to start our client app with a non Windows administrator account and got an "Access denied" exception from the .NET framework, because the client app tried to register a callback URL (e.g.: http://localhost:8030/ClientCallback/ ) . We do not get this exception when we execute the client app with a local windows xp admin account - of course.

• Visual Studio 2008 (Pre-release) Rockside Query Framework

  I mentioned this a few months back to Kieth Farmer and had no time to actually post this anywhere. I loved LINQ when I saw it at PDC 05 and wanted to experiment with building an IEnumerable based query framework with many of the same features. The purpose of the Rockside project was to emulate much of what's in LINQ without the need to use a special compiler. I've finally been able to start blogging about the Rockside project as well as take a deep dive into LINQ at my blog at http://community.bennettadelson.com/blogs/rbuckton so for those of you that were curious back in november/december of last year when I mentioned it i'm starting to post content now. I'll have the whole Rockside query project (including source) up on the site in a ...Show All
