How could i use escape sequences in VB to write strings like this: 'a1 "b1" c1' - where ' is a substitute for " ?

Heya,
" is escaped by "" (ie double 'em).
/WW

In VB you could use two double quotes back-to-back...
"a1 ""b1"" c1"
...or use the actual ASCII/ANSI char itself...
"a1 " & Chr(34) & "b1" & Chr(34) & " c1"
I prefer the first method.

I have a form and I want to make it so only one instance of that form is opened. I can do this with a counter variable in my form class so when it is loaded it incremenets and if they go to file->exit it decriments. But if thye hit the X button in the upper right, the form is closed and my counter vraiable stays at one. I need a way to make it so however they close it my counter is updated accordingly.

I would suggest that you use the Singleton pattern instead of tracking counters.

A singleton pattern is?

the following is similar to how the vb6 upgrade wizard does it. it's not a true singleton pattern, because it allows for more than one to be created over the lifetime of the app, but is close enough in that it never allows more than one at a time.
add this code to your form, substituting "Form1" for the type of your form.
Private Shared m_SingleInstance As Form1
Private Shared m_InitializingSingleInstance As Boolean
Public Shared Property SingleInstance() As Form1
Get
If m_SingleInstance Is Nothing OrElse m_SingleInstance.IsDisposed Then
m_InitializingSingleInstance = True
m_SingleInstance = New Form1()
m_InitializingSingleInstance = False
End If
SingleInstance= m_SingleInstance
End Get
End Property
now when you want to create or reference your one form, use Form1.SingleInstance instead of creating or showing it manually.

There are a couple of others there too: factory and .. er.. I forgot.

Just curious - why did you change your nick to jkgh?

How could I do this? I have maybe 16 different pictures that could be displayed in a picture box depending on certain things, and this picture can change at runtime.

The picture in the picture box needs to change at runtime.

' set the image
Picture1.Picture = LoadPicture("C:\Path\To\pic.bmp")
' clear the image
Picture1.Picture = LoadPicture()You could also use an image list as well.

hi,
I am trying to implement an array of images that will perform one function when clicked, and another when dropped onto another control.
Drag and drop works fine, but the problem is I am losing the use of Image_Click/MouseDown/MouseUp and so I can't get the code together.
I apologise in advance if this is a trivial query, but it is really beginning to annoy me!!!!
Charlie.

Hi,
I have a Visual Basic 6 application with an executable that is about 800KB. The application uses various active x dlls. No other application uses these dlls.
What will the advantages/disadvantages be of adding the active x dlls into the project and compiling it as one? It sure would make maintenance much easier.

It's always a confusing problem to me:when i finish a application and want to distribute it,i must create a setup and make a package for it.But how can i know which components(like DLLs,.OCX,.tlb and so on) i need and which information i shall write into registry...
In fact,i wrote a program in VB,then i use the tool "Package and Deployment" to create a package.But when i tried to setup it to test,it failed,noting me that the file "$(selfRegistryEx) " not found in my Temp folder.I dont know where's wrong

The package and deployment wizard is a good tool, and its always detected all COM dependencies for me.
You might want to try the Visual Studio Installer. It uses the newer Windows installer .msi format. (Requires InterDev)
Note however I think that there's a problem with using vsi1.1 for VStudio 6 and having Visual Studio.NET installed on the same machine. But in that case I beleive you can use VS.NET deployment project to package your VB6 project.

Although they cost money, installshield makes some pretty good products. You should check them out @ installshield.com. But like I said, they'll cost ya.

What about VC programs? Are these tools available to applications written in all environment(or in any language)?

I have massive spreadsheets of data to wade through and am hoping to automate the process.
I would like to make a chart of the data (x-axis is time stamp) and then have a script/macro so that I can go through plot and pick off data points by clicking on the plot. The script would read off the time-stamp and value of the closest point to my mouse click and paste it into another Sheet. I currently have to hold the mouse over the data point until the value pops up in a Tool-tip and then manually enter the value, or copy it from the original massive list.
Thanks for any ideas or suggestions!

has anyone here been able to get this control from Carlos H. Perez:
http://www.codeproject.com/cs/miscctrl/OutlookBar.asp
...to work in VB.NET?
I have been trying to convert the sample application over and am running into a few headaches that I can't seem to solve.

You could always use Carlos's Outlook control within your VB.NET application, that's what is great about the framework. You were trying to port this over to VB.NET weren't you???

Not the control, just the sample application. I have it done now. I ran into some stickey parts trying to convert the C# sample over.
