• .NET Development async web method calls being 'lost'

  Hi, I am trying to prove the benefit of async calls to web methods over sync calls. I'm working in .NET 2.0/VS 2005. I have a desktop test app, looping round, and calling my web service thousands of times, e.g.: ... For i = 1 to 100 m_objService.TestCallAsync(myparams) m_objService.TestCallAsync(myparams) m_objService.TestCallAsync(myparams) m_objService.TestCallAsync(myparams) Next ... However, when i look at my service logs, only some of these calls have made it through to the service. When I run the same code synchrsonously (e.g. TestCall rather than TestCallAsync), i get the correct number of calls logged in my service. I assume that I am overloading my web service by firing off so many as ...Show All

• Software Development for Windows Vista Outlook 2003 or 2007 RPC/Http using Vista

  I use 1and1.com and a hosted exchagne account. My old machine (XP/Outlook 2003) could connect to the Exchange server using RPC/HTTP and a hotfix from MS. Now that I have upgraded to Vista, I am not able to get to the Exchange server. is there a simlar hotfix that will allow the HTTP tunnel or is there some config in Vista that will let me achieve this using Outlook 2003 Bonus, I have a copy of Outlook 2007 which I would like to upgrade to as well, but 1and1 does not yet support this, at least not in tech support. In thinking this through, this is actually a windows issus vs. outlook (I think) so if i can get vista working, then theoretically Outlook 2007 shoudl work as well. Thansk t.a.

• .NET Development IrDA Connection Event - ManagementObject?

  When Windows connects to an IrDA device then there is an icon in the Windows Statusbar - notification area (bottom right). The Bubble help show "Device is in range". Is there a way to capture this system event from within an application. I want to give an indication from within my application that an IrDA device is in range. I know that ManagementObject, ManagementBaseObject and ManagementEventWatcher are possible classes that could be used to capture system events. But I find these very difficult to understand and I do not know how to set them up to capture the "IrDA Device is in range" event. Any suggestions Thanks! The http://32feet.net/ library provides .NET access to IrDA (and Bl ...Show All

• Visual Studio Team System How to add custom counters to default graph in load test

  Hi, I've a set of counters which I monitor when load tested and this counter set does not change. Is there any way to modify .trx file to show custom counters plotted by default I now see that only UserLoad, Requests/sec and AverageResponseTime are being plotted. Please correct me if I'm wrong.I'm assuming that the default counters to plot has been specified somewhere in the .trx file. I had a glance at the trx file but couldn't find the position to add my counter set. Any idea where can I specify the counters so that they are plotted by default when I open the .trx file Thanks in advance. You should not add them to the .trx. The .trx has the state for a specific run. If you want to add specific counters that are graphed ...Show All

• Visual Studio Express Editions Need help in returning an array from function

  Here is my function to bubble sort an array: int * bbs( int size, int * arr) { int temp; for ( int i=--size; i>=0; i--) { for ( int j=0;j<=i;j++) { if (arr[j]<arr[j+1]) { temp=arr[j]; arr[j]=arr[j+1]; arr[j+1]=temp; } } } return (arr); } In main program, I used this: int a[11]=bbs(11,a) to call the bbs function.( I already made the header). I looks up on msdn database and find out that I can not return an array from the function so I used pointer instead. However, I don't know how to execute this function after fixing it to what msdn suggested and the above implementation keeps giving me this error: error C2664: 'bbs' : cannot convert parameter 2 fro ...Show All

• Windows Forms Slow Form Rendering

  Whenever I have 100+ controls on a form, the render speed is very slow. Even on a fast machine, I can still see the controls being drawn on the screen. Is there a way to freeze the screen and unfreeze it after everything is finished render Or is it a problem with the CLR and nothing can be done All the controls are added via the designer. Suspend and Resume layout ARE being called. In fact, the slow down happened AFTER form.show(), at that point all controls should have been created. ...Show All
