• Visual Studio Express Editions I want to save Variables in a .txt file and upload them every time my program opens.

  I want to save Variables in a .txt file and upload them every time my program opens. I searched on the site for 2 hours and had no luck finding an answer to my question. So if someone could answer it or point me in the right direction that would be great. I have a program with a few variables. One of them is a string and the rest are colors and integers. I need some way to have my program save these to a file on my computer. Also when I start my program I want it to check those variable and put them in their proper location on the form or in the code. It doesn't have to be saved in a .txt file. If anyone can tell me the how to do this that would be great. Thank Spotty, I am pretty new to VB programming, so please bear with m ...Show All

• SQL Server Replicating Schema Changes

  Hi there, I'm using Sql 2005 merge replication and I have noticed something, I'm not sure if this is true or not:... My publication is set to replicate schema changes (replicate_ddl = 1). Now, I have noticed that schema changes are only replicated if the current snapshot is valid. Is this right If so why My next question carries on from the first. If I'm about to run a TSQL script on my publisher that will add a column or two to a published table, how do I ensure my snapshot is valid inorder for the ddl changes to be replcated Should I be using: EXEC sp_mergearticlecolumn @publication = <publicationname> , @article = <article name> , @force_invalidate_snapshot = 1 , @force_reinit_subscriptio ...Show All

• Windows Forms MS Access linked to VB 2005 problem

  hi all at the moment i am trying to basically link MS access database to VB 2005. I created a simple Database consisting of 1 table only. The table has ID,Name and Surname sections (with ID having a primary key). I entered some names and ID number so i can try and retrieve that information from it. I created 2 simple forms using VB 2005. One had a button and a textbox and the other had 2 label boxes. What i am trying to do is, when i enter the primanry key in the textbox and click the button, the information stored in the database gets copied into the 2 label boxes on my 2nd form (in this case i only have Name and Surname to be copied).

• Visual Basic Send output to stdout from gui app...possible?

  I have a simple vb.net gui application (an alternative file requester in a form) that I would like to run from the command line. It executes fine, but I find that I cannot send any output (a string representing the file selected) to the command line upon completion. It appears that "console.writeline" doesn't actually write to the console Any suggestions as to how to send info back to the console window upon completion Keep in mind that this is a gui app (not straight console).

• Audio and Video Development Programatically setting the default playback device (and recording device)

  Under Vista is there a way to set the default playback device programatically I've searched through the APIs but I'm not seeing it. For example, there is a method IMMDeviceEnumerator::GetDefaultAudioEndpoint(), but there is no corresponding IMMDeviceEnumerator::SetDefaultAudioEndpoint(). Can I do this through the endpoint properties Thanks, that's a helpful suggestion (although in our case, it would require a substantial rewrite of our control panel, so this might be more of a long-term solution). Some of the most useful features of our control panel can't be implemented this way, though. We have a "preset" feature where a user can create named sets of all of their audio settings and easily switc ...Show All
