• Visual Studio 2008 (Pre-release) What happened to ServiceHost.Throttle

  The title says it all really.  The ServiceHost generic used to have a property named Throttle which allowed setting of no. of concurrent threads and so on, but this has now disappeared/moved. Anyone know where it went David It's been a week since I posted this question and still no replies.  Perhaps I didn't explain why it's a problem. When writing a service using MsmqIntegrationBinding, the new ServiceHost appears to read every message out of the queue, start a thread for each and try to process them all at once.  This is NOT the desired efect.  For starters it makes the priority queue feature of MSMQ useless - yo ...Show All

  I have a shape like this shape , and I want to fill it with a color, can someone help me Greets, DIII I don't know why the GDI FloodFill function is not offered in GDI+. You could pinvoke it, or ( assuming you're still working on this drawing program ), you could accumulate an array of points as the user draws, and then use the FillPath function ( from memory ), which takes a Path built on those points and will fill it as well as draw it, with the brush of your choice. ...Show All

• Visual Basic DirectX Samples complaining

  A few days ago I've installed the directx9.0b sdk. I looked through the vb tutorials, and the first 4 seemed to work well. But the rest didn't work, the compiler complained alot about the directx library not containing stuff. Any idea what's going on here I hope I get some answers quickly, Michel EDIT Sorry, the tutorials work, but all the Samples don't. I would hazard a good guess that 1. You havent referenced the DirectX dll - which you need to do by going to the project and Add References 2. Havent specified a imports statement with the correct namespace and are not fully qualifying the ...Show All

• Smart Device Development How to use multiline button text?

  I see that in vs 2005, writing in vb, that it can now apparently handle multiline button text. On the IDE, in the box that asks for my text, I can click on the drop down, and it opens a window where I can type in something like: Main Menu (having pressed my Enter key after the word 'Main') and it shows exactly like I want it on the IDE. (Actually, I did not have a blank line between the two words--it's just doing that in this text editor). And, when I look at the generated code, it shows where it included the carriage return and line feed. The problem is that when I deploy the program, or run the emulator, it does not show both l ...Show All

• Visual Studio Team System Data Tier Problem

  Hey, I wanted to create a test environment. So, I installed everything as I was supposed to, and then I backed up the production DB and restored it to the testing environment. Then, I used TFSAdminUtil and specified the new data tier. Seemingly, all went well - no error messages, I even checked up on one table (subscription) in TFSIntegration and it pointed to the new data tier - great. However, today, I was startled to find that changes I made to work items on my testing environment changed things on the production environment! Then I took a quick look in the TFSWarehouse to find out what was the last work item id and foun ...Show All

• Visual C++ Semaphore Vs Critical section

  What are the advantages of critical section over semaphore or vice versa A semaphore can be used accross project boundaries. a critical section not. A semaphore can allow multiple processes/threads to gain access to it (as defined in lMaxCount), a critical section can be locked only by one thread. In most cases a critical section is much faster than a semaphore! ...Show All

• Software Development for Windows Vista Communication between 2 different workflows

  I have a host application (a windows service) and 2 different types of state machine workflows. The workflow1 executes a certain amount of workflow2 and waits for the workflows to return. To do this they need to communicate between each other. I thought workflow2 could send an event to workflow1, in order to tell him when he's finished. Everytime a workflow2 returns it send this event to workflow1, so workflow1 can check if the started workflows are all finished. But how can I send events from one workflow to another Any ideas, which dont use wcf Thanks You can accomplish this by having a local ser ...Show All

• Windows Forms Customizing DataGridView Selection Behavior

  I'm currently trying to use a datagridview to allow the user to select multiple items from a table. While the multiselect functionality will work for what I want. I would prefer to have the program only change the selection of the current cell when a cell is clicked. Or to basically have the program act as if the user was always holding down the Ctrl key for selection purposes. Additionally, I would prefer if I could also restrict selection based upon the value in the cell being selected. Looking around the net, I found vague references to being able to disable the ordinary selection behavior. However I have not been able to find ...Show All
