• Smart Device Development VS 2005B2 remote app running problems

  Hi, I used to be able to run/debug applications on my AudioVox smt5600 using Visual Studio 2005 Beta 2, but now it has stopped working, and I'm stumped about how to fix it. VS reports that the deployment has succeeded. I get the little multicolored pie thingee, but it just goes on and on, and never runs the application. If I navigate to the app via file manager on the device, I can run my app without any problems. If I switch to the release configuration, it doesn't make any difference. I've tried power cycles, making sure the debugger is off, etc. Does anyone have any ideas about what I can do next TIA -- ...Show All

• Windows Forms Extending ComboBox

  Hi all, I have inherited the task of maintaining C# code that was developed on NT. I am currently trying to build and run it on XP. It is building fine but isn't running. The problem is down to a combobox. The developer has extended the standard ComboBox to add some functionality but it appears that this extension has broken the ability to assign a datasource to it.   When I try to assign an ArrayList to it the value of DataSource is = null just after the assignment, however, if I assign the same ArrayList to a standard ComboBox's DataSource property the value = the ArrayList. Any tips would be brill. Thanks ...Show All

• .NET Development CPU usage

  I have to write a small service which will monitor the CPU usage and if a particular process consumes more than a predefined amount of CPU for a certain duration of time (that is, if this process is responsible for "hanging" the server), this service will kill that process and then restart it (of course, only if this process is one of the "custom" programs, not a system process). My question is: is there a programmatical way of determining the CPU usage at the moment [I am going to use a Timer which will do that once in a few minutes.] Could someone give me a link to an article describing how to do this, ple ...Show All

• SQL Server How to avoid user delete column

  Dear all I would like to ask one sql question , it's that possible to use statement delete my columns select * from tablename where columna = '--delete from tablename ' In particular, the statement (select * from table where column = 'delete from table') is not going to drop any column. But if you are concerned about SQL injection, that would be an issue if it's the user who specifies the column value. For example, let's say you get the user input in variable @col1_value and then you concatenate that and execute: select * from t1 where col1 = '@col1_value' If @col1_value is: val1 , the query executed will be: sel ...Show All

  I'm developing a windows application based on an Access database. I used the wizard to create the table adapters, relations and so on and all works fine.

My goal is to have a menu item like "Change db" where I can browse the file system and choose the db. Can I change the connection of the dataset at runtime How can I do Dado ...Show All

• SQL Server Clearing Single User Mode/lock

  What is the best way to clear Single User mode from SQL Server 2000 I have tried going to all tasks and selecting detach and clear Connections using this database. I then click cancel and go into the properties and options and clear the Restrict access check box. This seems to work some times but not all the times. I think it is because something else connects to it to it while I am going through the above steps. As a last resort I have detached the database and re-attach it. What is causing the single user mode to happen in the first place I am a little confused, the system is going into single use ...Show All

• Visual Studio Help not listed in TOC after install

  Hi All, I am finding a strange problem with the integration of help collection. In our case, help is installed using a VS setup program. This msi is being installed silently as part of another msi install. The help is registered correctly. The help collection is listed in the filter combobox for help-index, contents and search. But, say in contents, no contents from the help is listed. similarly for index, no entries from our help collection are listed. Search also doesn't work. I can get this working by removing our collection from VSCC and adding this again, I have to close and reopen IDE between and after these steps. ...Show All
