Dear Friends,
I have one simple sales and inventory control program. I would like to add in this project barcode system for some of the items. Can I enhance my system just adding this as a new future or else I have to do it as a separate project. Can u give me some hint how to use barcode system in the project. What is the logic for barcode system in VB6.
Please help me out in this technique.
Your quick response will be highly appreciated.
Thanks

Dear Zulnurain,
Thanks a lot for your quick response. I have downloaded the demo project for VB6 from the said website. But can you tell me how can I compare the item barcode with the one which I scanning at selling time so that I can take the salling and cost price of the item from the database. can u please explain with sample code.
or example I have one item name "camey soap" with barcode 1234567 how can i find the cost and sale price for this item from database while scanning the item.
Your quick response will be highly appriciated.
Thanks
Murtuza Patel

for Barcode System, Diff Barcode printers available in market. for example ARGOX, TSC, Zebra, SATO and much more.
Printing of Labels frm Printer is depend on PRN file.
Each Barcode Printer hv different .PRN File.
For Example: ARGOX Barcode Printer
1)First Load Argobar lite software and their drivers.
2)and through Argobar Lite software - make the lable of as per requirement of Label Width and Height.
3)USE in it Smooth Fonts then take PRN file.
4)and In that PRN file, pass variable from database
JUST like that diff. printers ve diff. Procedure.
Other Method is: If ur using Crystal Report then Directly make label as per requirement and pass variable in it. and for BARCODE lines printing take free download fonts for example CODE 39 or Code 128 for Barcode Printing.
And print it by any printer , Means Laser printing or anyother Barcode Printer

Hi, i have a problem with printing prn file to ARGOX printer..
i already generated prn file from ARGOlite software but when i print this file to ARGOX printer,
the result is not the barcode but, it show the content of prn file itself(syntax). But if i print directly from ARGOLite, the result is the barcode.
Is there any clue.??
Thanks

not sure adzactly but in vb6 you used the shell command
If you search in the object brower for shell the only 1 that pops up is
Microsoft.VisualBasic.Interaction.Shell(String, [Microsoft.VisualBasic.AppWinStyle], [Boolean], [Integer]) As Integer
Try searching msdn or google for a vb.net version
hope this helps a bit

I have not tried this myself, but it should be possible to automate a PowerPoint application from another.
You'd need to instantiate the PP application object from your program and then send commands to it via the PP API or object methods.
I know this is fairly easy with VS 2005 and Visual Studio Tools for Office 2005, but don't know how easy it is in prior versions of VS or VB.
Have a look at the MSDN[^] web site (especially the VSTO section for Office applications). Maybe there will be a sample or something to help.

I am trying to show a winform window using threads like this
Dim aFrmAlertPopUp As New AlertWindow(messages, altSysOrigin, alertId, BgColor, userAlias, altTeamMember, altAlertType, "SAS", Me.ControlToUpdate, "", alertGUID, alertCaseNO)
Dim backgroundThread As New Thread(AddressOf aFrmAlertPopUp.display)
backgroundThread.Start()
The Class AlertWindow works like a msn messenger warning window, when I instantiate I pass the values to the class
then I call the method display that will load values and display the window
this is how it was before (when it was actually working)
Dim aFrmAlertPopUp As New AlertWindow(messages, altSysOrigin, alertId, BgColor, userAlias, altTeamMember, altAlertType, "SAS", Me.ControlToUpdate, "", alertGUID, alertCaseNO)
aFrmAlertPopUp.display
Now, when I call backgroundThread.Start() it doesn't work
is the thread.start() the right call?
Am I doind anything wrong?
thanks

After searching many sites trying to find a free custom propertygrid / propertylist i have come up empty handed, there are a few for c++ but nothing free for vb.net. I reason i am looking for a free propertygird is because i want to use it in a open source project i am working on.
So i decided to have a go at creating one myself... this being my first custom control that i have tried to create its proving to be a chalange. Ok any anyways lets see if anyone can help me with a few problems.
I have a collection for Categories and a collection for Entries.
Cateogies are like the headers as such with the + - in the propertygrid
The entry collection is a object. I then set the object to say ie a textbox entry or a progress bar entry...
This has all gone well so far.
Problem/Suggestion 1
I basically draw the lable on the left, value on the right using drawstring. When i click on an entry i then dynamically add a textbox basically the size of the value side. I set the focus to the textbox. Set the value of the textbox and hide the border amoungst other things. Is this the best way of doing this? This method works, but seems a bit clumsy when font size changes. I was thinking that maybe instead i need to capture keypresses and use draw string to draw changes unstead of using a textbox.
Problem/Suggestion 2
I am going to use the render part of controls to draw the progressbar and buttons. But a control i am slightly lost with adding as an entry is a combobox. I can add the combobox like i did with the textbox above but i cant resize the combobox small enough to the size i would like it without it screwing up. Using the renderer i can draw the button for the combobox but yea i dont know how to draw the actuall box part. I started to experiment with adding a usercontrol with say a listbox and then showing that as the drop down part. Does any 1 have any suggestions on this?
Problem/Suggestion 3
I supose i will at some stage want to show tool tips for half hidden lables or values ... any one know where to begin on this?
if u would like to see what it sort of looks like atm

the horrible choise of colours is just to see where things are drawn
Thanks

Hi folks,
I'm wondering if anyone can give me some pointers to how to trap a MessageBox put up by a web broswer that's lauched by VB.NET. Or you can offer advice on what I should be doing.
Here's the scenario.
I'm on a Windows Server 2003 system in VB.NET. I send information up to a web site. If an error occurs, an HTML page with Javascript code is returned. That javascript contains the line
<body background="/images/comsplit1.gif" onload = loadDates(document.Schedules_form),fieldFocus(document.Schedules_form),noSchedulesFound()>
The noSchedulesFound() is an example of one of a number of function calls in the code indicating the error. All the error functions call the JavaScript alert() function with a text message, which basically brings up a message box with this information. The problem is that this is automated system running on a server. No one is going to be there to see the message box.
What I want to do is trap the message being displayed and write it somewhere else. I could of course parse through the HTML file and Javascript code, but that seems not as robust. I don't have control over that and I'd rather trap the message itself at the MessageBox level so if the structure of the messages changes, nothing breaks. It's safer to assume that it's always going bring up a Messagebox since this is an interactive HTML page. I could also intercept the HTML page and write in some
Javascript code which would send the message elsewhere, but again that is very dependent on the structure of the code.
So if I were going to trap the MessageBox, how would I do that? I've not been able to find anything on how to tell me to do that easily in VB.NET. I can't find an event I can hook when a MessageBox comes up. I'm hoping I don't have to go down to the subclassing the window level in Windows Programming. That's not something I've done before.
Any pointers would be much appreciated.
Rob

I wrote this code, it let me to free drawing in PictureBox1. But i want to use the image of it to do smt else. e.g. copy to a bitmap object. But i can't, it show that there are "nothing" in the PictureBox1.image property.

Pls help me, i getting stuck at this point..!
Code:
Private Sub PictureBox1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseDown<br />
If e.Button = MouseButtons.Left Then<br />
mousePath.StartFigure()<br />
End If<br />
End Sub<br />
<br />
Private Sub PictureBox1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseMove<br />
If e.Button = MouseButtons.Left Then<br />
Dim g As Graphics = Graphics.FromHwnd(PictureBox1.Handle)<br />
Dim myPen As Pen = New Pen(myColor)<br />
mousePath.AddLine(e.X, e.Y, e.X, e.Y)<br />

End If<br />
<br />
textX.Text = e.X.ToString()<br />
textY.Text = e.Y.ToString()<br />
End Sub

That is because you don't have an image in the picturebox. You are just drawing on screen where the picturebox happens to be, you are not drawing in the picturebox.
Create an image (Bitmap) and put that in the picturebox. Then you draw on the image by using Graphics.FromImage(PictureBox1.Image) instead, and invalidate the picturebox to make the changes visible. As you have drawn on the actual image in the picturebox, you can then save what you have drawn.

I'm doing something similiar but I want to copy only a portion of an image in a PictureBox control then save it as a new image.
This is as part of a small app I'm writing to crop images using a rubber-band type tool to define the area of the image to save. I have the image loaded into the PictureBox control and I can do the "rubber band" effect to draw the rectangle... but I can't work out how to then create a new image or bitmap from the area of the loaded image defined by the rectangle - anyone know what I need to do to do this?
TIA for any pointers or advise...
Mike

Create a new Bitmap with the size of the area, and draw the selected part of the picture box image on the new bitmap.
