• jdang Getting and Inserting Data using Combobox Selected Index

• Krutika Winsock Trouble

  I have a server that I am trying to send commands to. I am using the winsock control in VB. I can connect and send requests and when I look at the log files in the server I can see that I was able to connect. However, the server does not receive my request until I close my socket in VB, therefore I never receive data in the DataArrival Event and the server never processes the request. Has anyone ever seen this before and does anyone have any suggestions on how to make sure the server receives my request without having to close the socket Does the winsock control have a flush method are you using VB.NET or VB6 VB6 is unsupported and these forums are for .NET develpoment ...Show All

• John123 Suppressing events such as text change

  how do i or can i suppress events such as text changed. cos i want to set text in code and hence so not need it to be validated and stuff The standard method has been to use a flag to indicate that you are setting the text through code. This usually ocurrs when the form (for example) is loaded or initialized. There would be a class level flag: private LoadingFlag as boolean In the load/new event, you would set it true prior to setting all your boxes: LoadingFlag = True ' Start Loading... ' Set all Text boxes, etc. that raise 'changed' events LoadingFlag = False ' Done In the Changed event for the control you would look at this flag. if LoadingFlag = True then Return ...Show All

• millie_w Printing - skip a page

  I'm using the PrintDocument's PrintPage event to do my printing. All works fine, but I can't figure out how NOT to print a page of a multi-page document. Even if I never call DrawString inside the PrintPage event for a particular page, a blank page is sent to the printer for that page. I see what you're saying. And I can see how that could work. But it seems kind of kludgy, tho. Is there really no way to set a property, for example, that says, "hey, just skip this page" Say you want to skip page #3. When the 3rd PrintPage event fires, just render the contents of page 4... Ok, thanks, nobugz. i'll give it a go. No. ...Show All

• FC-Shiro print resolution hp 7350

  dpiX = e.PageSettings.PrinterResolution.X or pd.PrinterSettings.PrinterResolutions.Item(i).X or dpiX = pd.DefaultPageSettings.PrinterResolution.X returns the resolution in dpi for most printers, but an HP7350 photo printer and others return a value of -1 or -4 (instead of the normal 600, 1200, etc dots per inch) How can I get the resolution of these type printers . Just knowing it is HIGH or whatever does not help. I need the number of dots. Thanks, Tom tracks2009, Firstly, I suggest you to make sure the HP7350 printer can work normally under your current operating system and you install all the correct drivers for the device.

• Adrian_Moore Processor optimized compiler

  Hi all, I want to improve the performance of my application by compiling my application with a processor optimized compiler. Is there a vb.net compiler optimized for Xeon processors Now, I know that the vb compiler compiles the code into an intermediate language file. So I can’t actually see any improvements here, or am I wrong That’s why I think to use ngen.exe to pre-compile my application assemblies. Is there a special ngen.exe optimized for Xeon processors available Any answer could help me further. Regards, George Homorozeanu. The closest thing you're going to find to a processor optimized compiler is NGEN. I don't know if it specifically targets parts of th ...Show All
