UploadString (Post Method) Doesn't Work
May 8, 2009I am trying to post simple data to some site, in this example to a php file on my local server. My VB.NET Code:

Upladed the p.php to other servers, checked other variables in php ($_REQUEST), used the UploadString(URL,"POST","bla=test), used PERL, ASP.. nothing.I am using .NET Framework 3.5 how to Post data with vb.net?
Why Does One Method Of Declaring A Bitmap Work And The Other Doesn't
May 27, 2009I can't figure this out. I have a bitmap that will be used throughout an application, so I can't declare it with a Dim statement in a procedure, or it isn't recognized as having been declared in other procedures. So I declared it at the top of the form class, two ways. This one works: Private MyBitmap As New Bitmap(622, 461) It makes a bitmap to the exact size of a picturebox I have. But I want to be able to change the size of the picturebox and not have to worry about going back into this declaration to set things up, every time I decide to change the box's dimensions. So I tried this next version, but it doesn't work:

Visual Studio 2010 Created Program Doesn't Work On Windows7 64 Bit While Works Fine On Windows Xp
May 15, 2012I have one tool which we developed on visual studio 2010. there are basically two parts of my project, one is UI part which i wrote in VB and algorithm part which is in C++ on back end. When we compile C++ part it creates a .dll which is used by my front end VB program.
Now my problem is little weird since i am compiling and deploying this tool on windows xp machine but some of the users are using windows 7 64 bit machines and after running the program for about 5-10 minutes, it crashes on windows 7 with following error
Not enough storage is available to process this command and when i view details of that error, i get the following description.
See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.

Asynchronus Output Capture (BeginOutputReadline) Method Doesn't Work From Separate Class In VB
Jun 11, 2012I've got a simple tool written in VB in VS 2010 that has a series of command buttons which run Windows command files and the output is sent to a Rich textbox object on the main form (the comand files take awhile to run so I wanted the output to show up in the RTB as it was produced to show progress). All worked well until I made an update to the tool so that the series of buttons are no longer hard-coded, but created dynamically from information in the app.config file. To do this, I use a button

Use An Extension Method Instead Of Just Creating Non-extension Sub Or Function?
Dec 3, 2009Why would I use an extension method instead of just creating non-extension sub or function?
For ex, I could have an extension function called IsNullOrEmptyOrAllSpaces on String, which does a check as its name implies. Or I can write a stand alone function that does the same thing. Other than having the extension show up in Intellisense, is there any advantage? Is a call to the extension quicker/more efficient than a call to a regular function?

Why Doesn't The DeleteDirectory Method Of The Computer.FileSystem Class Work On "special" Folders
Aug 14, 2008if they choose to use a networked version of my software, I will need the main server doing the authenticating. This is a problem, because from what I understand, it is quite easy to clone MAC addresses. I have looked into using the CPU ID and the HDD ID, but those are not unique, well at least I don't think so. Reason why I say they are not unique is because someone has the exact same CPU ID as me, and the HDD ID changes from partition to partition (same drive). Maybe the HDD ID is a partition ID instead? Anyways, I was thinking maybe I could get the Physical serial number of both the HDD and CPU, but I have not been able to find anything yet.

View 2 RepliesDetermine Whether A Method Is Declared Normally Or As An Extension Method?
Jul 16, 2010Extension methods are useful for types that you don't own and can't/don't want to derive from and extend (e.g. reference types and interfaces). Obviously, interfaces should be kept as short and to-the-point as possible, so extension methods for interfaces are particularly useful (e.g. LINQ).For classes, especially classes that you own, they're still useful - but I'm wondering how you determine what should be an extension method or what should be a method in the class itself.Personally, every time I think about it, I keep going round in circles with the following thoughts:If it's useful enough, it should be in the class.It's not part of the core responsibility of the class, it should be an extension method - but if it's useful enough, surely it should be the responsibility of the class...

PerformClick() Doesn't Work - How To Make It Work
Feb 2, 2011I have an application that requires data be entered, and after entering, a button is clicked to process that data. Clicking the button works just as it should--the data is processed properly. In constructing a test module, I provide a set of data values, followed by:
btnWhatever.PerformClick()
Nothing happens. I have used this syntax for years, and it has always worked flawlessly. I have triple checked everything else and isolated the problem to the failure of the PerformClick(). The PerformClick() is in a test subroutine that does nothing but fill textboxes and labels with default data, then calls the PerformClick() on the button to begin processing. Again, the button works fine, the data is entered as it should be, but the PerformClick() does not fire the click event.
