View 1 RepliesI have two questions for anyone who can throw some idea's my way question 1:I am currently working on a control with three combo box's. This control will be nested on a form, and I want the on-board timer to track how long each control is active. I am trying to use the focus events of the combobox's to determine if the control is active so the program will know when the timer should be started and stopped. My problem is, for example, when the user causes the text property of the combo boxes to change, the folowing code runs:
[Code]...
As you can see, there are points in this sub-routine that can cause the focus to shift, as well as fire the text changed event. While this all happens faster than is really noticable, I would like to eliminate the extra cycles if at all possible. As I mentioned in question one, I am adding this control to a form, to be more clear I am adding multiple instances of this control to a single form, and I am trying to use the focus events to determine which of the controls within the form are active; however, when the form itself is no longer the active application, whether it is minimized, behind another application or otherwise, all of the timers stop. I want whichever control was active at the time that the form was deactivated, to continue as if nothing changed.
I am having 3 radio buttons and a button The codes should be added to the button_click event, when ever the radio button is selected and the button is click then, The codes should determine which button is selected and assign it to a variable.

View 1 RepliesFirst off a short background of the project I am working on- I am developing a program that will be run off removable media (i.e. USB Flash drive). This will be a �virtual desktop� which you will be able to take with you and have the same �desktop� on any system. As we know drive letters can change with each host system the drive is plugged into, I need to be able to determine the path for the flash drive and access a specific folder ( i.e. My Documents)
I have an picture box(representing the icon) placed on my form (form1) and when I click the icon I want to be able to open and view the a specific folder from the portable drive. I need a click event that will determine a dynamic drive letter for a directory on the removable drive and then open that directory in an explorer window.

View 2 RepliesI have been using VB2005 for many years on 2 PCs. Over the last month I have been getting an error when I try to run the project from the IDE:
Error 1 Unable to copy file "objx86DebugBackup.exe" to "binx86DebugBackup.exe". The process cannot access the file 'binx86DebugBackup.exe' because it is being used by another process.
C:WindowsMicrosoft.NETFrameworkv2.0.50727Microsoft.Common.targets 2324 9 Backup
My questions:
1. What has changed?
2. One thread I found suggested that it is a bug, but if true is this something that has been introduced recently (I'm not aware up updating VB2005 unless it happened as part of the general updates).
3. How do I get it back to where it was?
The file is actually locked by my own process, no other application can be using it. I've even tried it with a few line noddy program. I always have to come right out of the IDE, wait a couple of minutes and then go back in - a total productivity killer.

I have a filesystemwatcher waiting for .jpg files to arrive from the camera.he file system watcher invokes a delegate (it works but is that the proper way to handle it?) sub that does a couple of things:1. Adds the just arrived file name to a table2. Attempts to display the image in a picturebox on the form. When it displays the image it imprints some information on the image that the user has entered on the screen. I use a file stream to retrieve the image.The problem is, I'm getting a file in use orror on the "Img = ystem.Drawing.Image.FromStream(fs)"statement. Not all the time. Sometimes I can add three or four files to the folder in rapid succession with no issue. But then out of the blue the error will occur. Sometimes it's there to stay but other times it will go away and allow me to add morefiles.

View 4 RepliesWe have a stored procedure that executes in a long time so we decided to enclose it in a thread. Before executing the long stored procedure, the procedure should be locked so that only one user can execute the thread. However, I have noticed that a user can still execute twice. Here is the code. [code] The problem is when I tested the code by opening two browsers then simultaneously process, two records are being inserted into our lock table. The second user should not be able to process because the DoProcess is already locked.
