Opens a serial connection when a radiobutton is selected. My question is: How can I make a message pop up saying "COM Port in use" if the radio button is selected when the com port is in use by another application? Right now, the program just crashes.
In the developing environment the computers do not have com ports, but I am working on a project for a client who does. It is annoying that when I test the program on my computers I always get the error. "The port (COM1) does not exist"
I am catching the general exeption but the debugger stops there anyway. I can press "continue" and the program resumes but I would like to clean that up and not try to open the port if the computer does not have one.
vb.net
Try
SerialPort1.Open()

lblNoCOM1 just tells the user that there is no serial port and that the barcode scanner is not working.
I have an app. (with out source code) that has some where about 20000 records in it. I want to extract all those records through my app. and save them somewhere (in vb.net ).
View 3 RepliesSo the app that I am working on requires me to launch shell commands that output text into a command prompt window. I need to be able to capture that text into a string.
View 3 RepliesI had an idea for an MSN (Windows Live Messenger) "addin" today, which I thought was a great project for me to try.Basically, I want people to be able to type LaTeX code in their MSN conversations, and my application parses the LaTeX code and displays (probably in a separate window, but if possible inside the conversion window) the math formula.
I am probably not going to get it to send the image in the conversion window, but I will be happy if I can get it to display in a separate window.Basically, all I need for this to work is to capture the text that a user receives over MSN. If it contains a certain token (like "$$ ... $$") then I can try to parse the text between the dollar signs, and if it is valid LaTeX I can show an image of the result in a separate window.
So, I probably don't even need an actual MSN plugin / addin, if I can just get the received text by some other means.
1. some basic Windows Live Messenger add-in programming examples / tutorials? I've never done this before, and have no clue how to do it... VB/C# are both fine.
2. how to retrieve the text that you receive using either an addin, or some sort of windows API ?
So I'm looking for either an addin, or, if possible, a completely separate application that basically monitors each and every window and sees if it's from MSN, and then retrieves the received text...
Using Winspy++ I've figured the structure of this program is as following

I'm currently working on web application using VB in ASP.NET.Right now I have 1 page with panels that we are using to show/hide depending on the flow. When the user first comes in, he/she is presented with a gridview containing a list of clients. Then the user, clicks a link from a row and is presented a form where he/she can update the clients' info.Originally, I had a HYPERLINKFIELD that put the clientId in the url, then I'd grab the url and do the code appropriately
<asp:HyperLinkField Text='<%$ Resources:Resource, ManageClient %>' DataNavigateUrlFields="CLIENT_ID" DataNavigateUrlFormatString="~/clients/manage.aspx?clientId={0}" />

Is there an easy way for me to capture some system data when I except? Particular memory information. I have a service that has been running fine for years, but lately it keeps having System.OutOfMemory exceptions being thrown at random. I want to determine what memory the system is actually using then if possible to see if I am really out of memory.
View 4 RepliesI'm currently developing an application on Visual Basic (2010) which requires the use of a Thin Client's serial port. I have already activated the port mapping, and tested the communication (successfully) with PuTTY. How ever when trying to use my software y receive a message The selected port name is invalid, or it is not a serial port.I have already made some successful tests with a common PC with positive results.

I was a professional software designer using VB6. Now that I've converted to VB2005 years later, use, with pages of unrelated information. With VB6 I could use Left$, Mid$, etc to parse keyboard input into a string. For example in the KeyPress event of a name box I could use
Case "A" To "Z"
CFName$ = Left$(CFNameBox.Text, CFNameBox.SelStart) + Key$ + Mid$(CFNameBox.Text, CFNameBox.SelStart + CFNameBox.SelLength + 1)
When converting a program from VB6 to VB2005 the software changed the line to
CFName = VB.Left(CFNameBox.Text, CFNameBox.SelectionStart) & Key & Mid(CFNameBox.Text, CFNameBox.SelectionStart + CFNameBox.SelectionLength + 1)
When writing another program I used the VB.Left(), etc, but it gives me an error. So, the question is, what is the correct way to capture keyboard input from text boxes and construct strings?
where I'm going wrong with my circular DirectSound Capture buffer here? If I just capture sound into a big non-circular buffer it works fine, but with a 1 second (44100 bytes) buffer and a 100ms timer to poll the read position it goes haywire. No error messages, just long blocks of zeros with short bursts of valid data. calculation of the number of bytes to read and/or the read position.
Here is the code. gBuffer is defined elsewhere as a big byte array. In this example I am just trying to copy the captured sound data from the small temporary byte array (tempBuffer) into the big gBuffer byte array. Obviously this must be done so that every byte is read and copied into the byte array with no gaps or duplication of values. Timer1 is set to 100mS:
Dim McaptureBuffer As CaptureBuffer
Dim MiLastReadPos As Integer
Dim MiBufferOffset As Integer

I'm trying to read barcode using a scanner through a serial input(com1). Below you will see the code I'm working with, when I scan the barcode the code goes through the datareceived event and doesnt add the read barcode to the listbox. However when I use hyperterminal and scan the barcode it reads and displays the barcode.

I have several UserControls in an ASP:Repeater. They are 'Add to basket' User Controls with a text input for quantity and a button to add the item to the basket.
My problem is the value is being reset to 1 whenever I enter a value into the quantity text box. I think this is happening because the containing page reinitialised the repeater (which holds the UserControls) and the quantity is one again before the UserControl's click event is fired.
how to capture the value in the textbox before the Postback occurs, I am happy to stick this data in a session for now.
I am thinking I need something along the lines of PreLoad? But that didn't work for me
ok the scale is a truck scale connected to a terminal (cougar 8530) that was connected before via Rs232 now the pcs doesn't have a serial port so someone attach a usb adapter to it the thing is i cant capture any data from it. im an developing a small program that can capture the weight of the truck (trucks are weight with the product and then re-weight with out it so they can find how much the product or products weight) so any ideas? suggestions?
View 1 RepliesThere is Bitmap data on the clipboard from a screen capture. If I paste it into a RichTextBox it works OK. That is, if I remove the first two lines below.
Dim clipboardDataO As DataObject = CType(Clipboard.GetDataObject(), DataObject)
Clipboard.SetDataObject(clipboardDataO)
RichTextBoxTxt.Paste(DataFormats.GetFormat(DataFormats.Bitmap))
However, If I capture the clipboard data and restore it before I paste I no longer get my bitmap displayed in the box. My problem is, in the real situation I need to use the clipboard before I paste which is why I save it and restore it above.
1) Do you know why restoring doesn't appear to work here?
2) I can't paste before the save/restore. Is there something else I can do?
In a Windows XP Pro environment, my system uses a mainframe emulator in a window in which a scanning application is running. The data populating the mainframe app comes from various instruments, scales, barcode scanners, etc.. The data inputs are captured by a winwedge type RS232 data aquisition software.
When all the data is processed correctly, the mainframe application sends an "operation completed" message and creates an exclamation system event associated with a specific sound to inform the user.
My goal is to create a MS Access application that would use the Exclamation system event to validate writing the barcode that was just read to a database without further querying the mainframe, creating a local database. I only want to write the barcode when the mainframe application completed and therefore played the sound.
