Deleting Files in Visual Studio/TFS Taking a Long Time

I needed to delete some files from source control and noticed that it was taking Visual Studio/TFS about 30 seconds to delete a file (move it to the delete pending list). Since I needed to delete a lot of files, you can imagine how annoying this was. So, I fired up good old Process Monitor and started watching devenv.exe. Then I went into Source Control explorer and deleted a file. Suddenly Process Monitor was full of folder accesses. Dozens of folders were being scanned. After some research, it turned out that when I deleted a file for some reason Visual Studio was looking through all the folders in the same workspace as the file.

So, I created a new workspace and put my project and only that project in the workspace. Now when I try to delete a file it happens very quickly.
Lesson learned.

Restoring Color Icons in Gimp 2.10

PowerBuilder and SQL Server: Tips On Working Together

I recently worked on a project that used PowerBuilder for the front end and SQL Server for the database. I've worked with both of these technologies in the past but this was the first time I used them together. Below are some notes about the things that I learned regarding PB and SQL Server working together. Single Quoted Strings If you do any work with SQL statements in SQL Server Management Studio (SSMS), you'll find that SQL Server only accepts strings if they are surrounded by single quotes. You can use double quotes in the PowerBuilder painters and they'll get translated properly on their way to SQL Server. But you may want to just go ahead and use single quotes everywhere, especially if you are trying to track down a problem by copying SQL from PowerBuilder and pasting it into SSMS. Identity Columns One of my tables had its primary key set in SQL Server to autoincrement. In my datawindow I would insert a row and then do an update. I was expecting the value SQL Server ...

A tip on multithreading in PowerBuilder

The way you do multithreading in PowerBuilder is to create an object that contains the code you want to run in another thread. You then create an instance of this object as a “shared object”. You also code another object – the “interface object” and pass the shared object a reference to it. You can then call functions on the shared object and have them run in the other thread. The shared object communicates back to the main thread via the interface object. The other day I set up a program using a shared object. I had a shared object that was running some code asynchronously. When it was done, it called a function on the interface object and the interface object called a function in my window to let me know it was complete (by setting a variable). At one point I needed to wait until the shared object was done with its processing before I continued what I was doing in the main thread. I had it coded something like this: Integer li_status Li_status = wf_get_status() Do while li_status = ...
