Visual Basic Conversion of Double to Single
I've been fighting with this problem for the past couple days and finally narrowed the problem down to the following couple problems: (This is all in VS 2003 .NET 1.1) #1 I have a Generic procedure that has a ByVal parameter of a Single datatype. In one of my modules, I happen to be calling the procedure passing in a Double datatype variable that has a value of 152347.04. When I step into the procedure, the Single datatype parameter then has a value of 152347.047. I've tried type casting the Double to the Single datatype but still get the same results. I can't figure out why it's not converting over the Double to a Single type by adding some erroneous value to it. #2 Also in the same procedure, I was passing in an ArrayList object that was ...Show All

Visual Studio Team System Saving attachments
To save an attachment you have to open it and then save it from within the application that has opened the attachment. In my experiences, IExplorer is always opening the attachments and sometimes failes to do so. For example: opening xml files for which the specified schema can not be found. Also for other file types like .jpg I rather want to save the files than open them in IE. I tried to change the file type associations as explained in http://support.microsoft.com/kb/905703/en-us , but no luck. (What's more, for file types for which I changed the default open-application, the Advanced button is missing in the 'Details for .. extension' dialog. Only after pressing the 'Restore' button I can select 'Advanced' and then check/uncheck 'Conf ...Show All

Visual C# How to disable abridging in an ArrayList object?
Hi! Let's say I have this object: private ArrayList aryClients; // list of Client Connections Now, on every client connection that my server gets I add a Client object to that list. It's all good, but think of this scariano: 4 clients connected. Now aryClients has 4 items from index 0 to 3. The 3rd client who's Client object is in aryClients has disconnected, so item 2 was removed. Now this is where we're getting into my problem; I want that item 2 will stay null and item 3 (of the 4th client) will stay at index 3. Why you're asking Because I need to have quick access to clients' info in my server (it's gonna be a game server), and making a search (thought about the Windows handle of the client's sock - uniqe) ever ...Show All

Visual Studio Express Editions How do I make the enter key handle a button click?
I have a form that has a combobox on it, if the user clicks a button after selecting from the combobox, another form will show. I would like to have the user select an item and be able to either click the button or just press the enter key on their keyboard. Thanks in advanced. I think what your refering to is more commonly described as the default button. If this is the case then setting the AcceptButton property on the form to the name of the button should do the trick. ...Show All
SQL Server System Monitor logging of SQlServer counters
I have SQl Server 2000 running on my winXP machine, and I can see SQLServier counters in System Monitor. But if I add them to a log file, they don't show up I can log regular windows counters (like memory counters) but no SQLServer items. And I have tried run as using the account I log in (with full privileges). What's the trick Thanks for the reply, but I'm just doing what every example shows, adding SQLServer counters (like GeneralStatistics.UserConnections or AccessMethods.FullScans) and they won't come up in the log like the built in System counters. ...Show All
Windows Forms Problem referencing items in a different project in solution
I am creating an Outlook style application with email and contacts. I have my mainForm which is in its own project. The main form has a splitter. One on the left for the tree. And one on the right for a grid. In the Contacts project, my contacts tree is a user control, with a treeview added to it, and it has another user control with a grid added to it. In my main project, I add a reference to the contacts project. When my program starts up, it programatically adds my contactsTree control to the left side of the splitter, and my contactsGrid control to the right side of the splitter. And so on, for the email it adds the email controls etc. When a user chooses email, the email controls are set to Visible, and the rest of the controls are hi ...Show All

Software Development for Windows Vista Controlling MSWebDVD buffer
Hello, I want to use DirectShow (the MSWebDVD control) in a vb project and I need access to the buffer. Basically, I want the program to automatically skip from one part of a movie to another while the movie is being played (say from 10 minutes into the movie to 12) and I want it to happen seamlessly. To accomplish this I need to alter the choice of data that is being buffered. I need the buffer to load the information needed to play the video that will come after the section is skipped (So, in the previous example, it would buffer the data up to 10 minutes and the next data that would be buffered would be that which is after 12 minutes). Is there a way to control what is going on with the buffer If not, can anyone suggest something els ...Show All
