• Visual FoxPro hiding Logon information....

  I have an online MySql Database that I will be connecting to in a distributed app. The user will Log in and all remote views will be filtered based on the userid. I have set up a user for my app that can access ALL the data. I can’t figure out how to hide the user name and password in the connection object in the DBC. If I use dbsetprop it actually updates the DBC Connection. Anyone with access to the dbc can access all the data! I want specify the User and password at runtime and keep it hidden in a compiled EXE. Can this be Done How I know I can do it with ADO but I prefer to use remote Views. ...Show All

• Visual C# How to Clear TreeView nodes?

  Hi. In my application, I run a BackgroundWorker to load content from the net. In BackgroundWorkers RunWorderCompleted event handler I want to populate a treeview based on the received content. But first I need to clear the whole treeview. When I try to clear the nodes using myTreeView.Nodes.Clear(), a TargetInvocationException is thrown. I never saw that before, so I think that background worker is to blame. Any suggestions how to clear the TreeView If one thread is trying to add nodes while another is trying to remove them, then bad things will happen, exactly the type you are seeing. Is this what's happen ...Show All

• Visual Studio Express Editions Best way to repeat tasks on a regular time interval.

  Using VB.NET 2005 I have a hardware device the constantly sending data to the PC serial port. I was wondering what the best way to poll the serial port for data would be. I was thinking of two different approaches. Any pros/cons or another suggested method would be appreciated. I'm kind of thinking that Option #2 is better programming practice. I'm just not sure where to start. 1) Put a timer on the form. Set the timer to trigger every 10 minutes. When triggered, the code inside the timer reads data from the serial port. This is an interupt of sorts 2) Have a seperate thread that runs in parallel with the main program look. Inside this ...Show All

• Visual Studio Team System I get the following error while loading my rule in FxCop.

  I've written several custom FxCop rules that I want to use with VS2005's Code Analysis engine, but I can't find any way to add-in my custom rules assembly. I know Beta 2 doesn't have all the documentation yet, but can someone tell me how to build a custom rules assembly for VS2005 and get it installed for use in a project Thanks! Now I'm not sure if this has changed in Beta 2 but in the CTP versions, you can change the rule assemblies by adding an MSBuild property called FxCopRuleAssemblies. Or if you want to change the rule assemblies for the entire system checkout the following file: C:\Program F ...Show All

• Visual Studio Console App blows up when I try to publish it. (GenerateApplicationManifest path too long)

  My console app was working perfectly in debug mode through the IDE, but when I went to publish it for deployment on the server, out of nowhere I got 2 messages and an error.I am using DAAB 2, and I have the common, data, data.configuration DLLs referenced. I have another app which is a VSTO app, which after much effort works fine. I compared my config files and they virtually identical, so why am I getting the messages on 1 and not the other. (Deployment is a real SOB). Anyway, I I got 2 messages and an error as follows. Any ideas would be extremely helpful. I have also posted the top of my app.config file.

• .NET Development Just got curious about why NGEN must put assemblies in GAC...

  I had expected that NGEN would generate a native assembly and I can pass it around. I am quite surprised that NGEN only put the result native image in GAC. Anyone can tell me a few reasons of this design This is a great question!  There are two issues here: 1) Why don't we allow you to pass native images around 2) Why NGen images are stored in the GAC Shipping NGen images is a feature that we looked at.  The difficulty here is that NGen images depend on the specific environment that they were compiled in (version of the runtime, version of dependencies, publisher policy, security state, etc.).  This makes NGen images not ...Show All

• SQL Server Dynamic Scripts

  I've found that SSIS does not work well with running small dynamic scripts ... For example, I have scripts that need be created via dynamic SQL. I want the dynamic SQL to be created using variables in SSIS. The ways around this are to create small temporary stored procedures that I can create in the SSIS package at run time that have dynamic SQL in it - and execute it with the variables as my parameters. Does anybody else do this, or have a better way of doing it I have just been creating stored procs and passing the parameters into them. This has been the easiest solution for me. ...Show All
