• Visual C# Offsetting UserControl location...

  I am having this annoying problem that I do not understand. I have a UserControl and I am trying to change its Location . I want to say: this .Location.Offset(iAdjustX, iAdjustY); However the above does not work. It seems I need to do this: Point pt = this .Location; pt.Offset(iAdjustX, iAdjustY); this .Location = pt; I do not understand why I cannot just apply the Offset method to the the UserControls Location . Am I missing somthing here Thanks, Bob Hi What I try to sey is that if we can change Location point directly we don't know what else we must do. Must we do Refresh, Invalidate or something else That's the reason why we must call properties set method. ...Show All

• SQL Server Very High CPU during Full Text population

  I am building my first catalog on my 2005 server. It currently has been running for almost 3 hours now when in 2000 it took a little more than an hour. It seems the bottle neck is my sqlserver. I know that there are 2 other services associated with populating the catalogs but they don't seem to be doing much but the sqlserver.exe is sitting at 98% cpu or more. This obviously is not good. I tried searching for solutions and found nothing that helps. I increases the available memory to the server to 2gb from 1gb but the server is only using 40mb anyways so that did nothing. I am not sure what to do next... The table that is full text has 3 varchar(max) columns plus 10 other varchar fields but I wouldn't think that has anything to do with ...Show All

• SQL Server use fixed name and password to access reports

  I have an RS2000 report project that is working nicely. I have embedded the links to the reports into my web application. They come up fine but they prompt for username and password. Most of the users accessing these reports are being authenticated via the application, they do not have usernames and passwords on the local server and the server is not on a domain. Is there any way to have the link include a fixed username and password to access the reports Thanks, Eva Yes, after you have published the report to the report server, you can access the data source properties for the report (Accessible via Report Manager, on the properties tab in a report). You can store the user credentials securely i ...Show All

• Software Development for Windows Vista Installation Directory Write Access Issue

  Hi, I am a developer for a commercial program and we are working on a Vista-aware release of our product. It is a large install (6 CDs) abd is currently all put in Program Files under XP. The Microsoft suggestion of putting program executables and static data in Program Files and all other stuff in the appropriate users/... directory is not practical for our application. I have never liked that model. It makes things complex both for users and programmers. It is a road that we simply will not follow. The problem, of course, is that users don't have write access to the Program Files folder unless they explicitly and manually set it. We could require the users to do that but this is not a happy solution and we probably will not do that. W ...Show All

• SQL Server Sending email to multiple recipient

  I am trying to send emails to multiple recipient using the Send Mail Task, but it is failing with the error: " The specified string is not in the form required for an e-mail address." It works when I have only one emailID in the ToLine, I have a script task that build the emaiID list and saves it in a variable and the in the Send Mail Task, I am using the Expressions for ToLine to use this variable. If there is just one emailID in the list, everything works, but if there are multiple, it throws an error. For building the emailID list, I tried using "," as well as by ";". But none seem to work. Any help will be greatly appreciated. The Send Mail task likely doesn't su ...Show All
