BilalShouman Opening Default Email Client
Hi, I'm developing an application using Visual Basic 2005 and I'm just wondering how I go about opening a new email using the default email client Basically, my application has a section where the user can enter email addresses. I want the user to be able to click on any of the email addresses and have the default email client set in Windows (such as Outlook or Outlook Express for example) open up a New Message window with the To field already filled in with the email address the user clicked on. I'm not sure if this is a Visual Basic related question or not, but any help would be much appreciated. Thanks. this could possibly be bad practice but this should work: Dim theStringBuil ...Show All

dacky Referencing a Form on a Seperate Thread...?
I converted my code from VS2003 to VS2005 and came across Cross-Threading problem, which previously did not occur in VS2003. I am developing a Client/Server style application where a great deal of computations takes place in either application. I designed a "Progress Form" that is used to, well you guess it, display the progress of some work. In an attempt to create code that could be universal used by any application, I decided to create a Class. I have a "Thermometer Class" that manages all the interaction of a "Thermometer Form". There is a reason why I used this duel object method of creating my "Progress Form". I want my progress form, when displayed, to lock the GUI but not to block the thre ...Show All
Bill Reiss How to use MemoryStream.Read Method
Hi, I am learning to use the MemoryStream class, and having a hard time understanding the documentation in MSDN ( http://msdn2.microsoft.com/en-us/library/system.io.memorystream.read.aspx ). I want to read the first 4 bytes of a byte array using MemoryStream, convert these 4 bytes to integer, and store them in a variable. Could someone provide a working example Thanks! well if the memorystream has the data stored in, and you want to read the first 4 bytes....try this: Dim theBytesRead() as Byte theMemoryStream.Read(theBytesRead, 0, 4) this will tell the memorystream to read into theBytesRead, starting from position 0 (first index) for the length of 4 bytes. Does this make sense so now you want to conv ...Show All

milicica does form exist?
Is there a way to check if a specific form exist from code Davids Learning To be honest, I am a C# coder, I answer in here because most questions are framework questions. That's why I asked if 'is' is valid VB syntax, I just didn't know. This syntax worked for C# in 2003 ( and 2002, I believe ). I have no idea if it's new to VB, or not, but I know of no alternatives. Or if you only want a single instance of a form to exist you can use the default instancing in VB 2005/Express to achieve this. Someone was looking to find all text boxes in the controls collection yesterday, and this code did not find MaskedTextBoxes, which is surely derived from TextBox ...Show All
