Hello,
I get the following error in run time.
Error message
Unable to cast from a number, the value must be less that infinity.
My code in vb .net visual studio 11
Form load
Me.Client = New DXProf(Me) --Excetion thrown here---
Me.components = New Container
Dim manager As New ComponentResourceManager(GetType(Form1))
DXFramework.m_Icon = DirectCast(manager.GetObject("$this.Icon"), Icon)
DXFramework.LoadInstance(Me.Client, Me)
End Sub
End Sub
Here is the exception detail.
System.InvalidCastException occurred
Message=Unable to cast object of type 'DXProf' to type 'idt.medical.IDXClient'.
Source=DXPro
StackTrace:

InnerException:
Any help would be appreciated.

What the (explitive deleted) is "DXProf"?? It's surely not part of the .NET Framework, so it's VERY unlikely anyone is going to know about it.
If it's a third party lirbary, you're best bet for getting help on this problem would be the people who wrote that library.

Dave,
Thanks for your info,
I am the only one working on this program. The original author is not with us anymore and I a picking up the pieces. I have so so source code and comments and no documentation either.
DXProf is a component in the app that works with externel .dll's. I personally would not have written it that way. But I have deal with what I have.
Thanks for your help.

This message tells you everything you need to know. You are trying to initialise a idt.medical.IDXClient object from a DXProf object, but the two are not compatible.

From this, and your other responses, I get the feeling you do not really understand inheritance and still have no idea what this error is about. You need to look at your class definitions to see why the two are incompatible.

In case that it was you (or someone of your colleagues) to develop that DXProf component, make sure that it inherits from 'idt.medical.IDXClient' (which might be an interface).
Actually I'd expect the compiler to complain - is there still some kind of "Option Explicit Off" in that version of VB?

Bernhard,
Thanks for the info, I am the only one working on this project, the last developer and creator is no longer with us. I having to reconstruct everything with so so source code and no comments or documents to speak of.
In vb 2008 and version 11 there is a few choices of option explicit, so yes I could turn it off. There is also option strict which can be toggled off too.
Now you said to make sure that the DXProf component inherits from idt.medical.IDXClient. Could you give me an example. Yes you are right idt.medical.IDXClient is an interface.
Please help if you can.
And Thanks.
Michael

Get the source code of DXProf, and change the class statement:
Public Class DXProf
Implements idt.medical.IDXClient
Then you'll likely receive some error messages that DXProf must implement this or that function of property. Just do that. Take care of the exact signature of functions.

It throwing an exception that:

Ah, you could have guessed that the error would be important. I haven't used DBaseIV in a few centuries, and I can't test your code; however, I guess that the table doesn't exist in the target-database.
Create the table by hand, run the code again. If it works, you'll need to write some code to create the table.

I've googled, searched CodeProject, etc, and I hope I'm overlooking something, but here is what I want to do:
I want to call a Windows Form application from another Windows Form application.
The program being called, may be called from different form based applications and needs to know who is calling.
I've found in testing, that with this code, I can accept a parameter:
Public Shared Sub Main() <br />
If Command$() = "/CR" Then<br />
strAppStartedFrom = "CR" 'Started from Check Recon Application<br />
Else<br />
strAppStartedFrom = "--"<br />
End If<br />
MsgBox(strAppStartedFrom & Command$())<br />
frmFTP.ShowDialog()<br />
End Sub<br />
I've published it, and from what I can find it puts the exe in this location?
C:\Users\username\AppData\Local\Apps\2.0\0BTCBQ53.QL1\OMCV071R.O93\carr..tion_c302ad764aefaa28_0001.0001_bcaadc20b696e727\CarrollFlexFTP.exe /CR
This path seems like it might change and not be consistent when installing it for different users.
The above link works if it is executed with a /CR parameter, but I need a more stable way of doing this.
In the past I've pointed shortcuts to the setup.exe file in the location we publish the application to, but if I run the app using the setup.exe /CR parameter, it doesn't work.
Suggestions?

It appears that you're using ClickOnce deployment. If you want a more stable path, then you can't use ClickOnce Deployment. You have no control over the path that the app is installed to.
KreativeKai wrote: The above link works if it is executed with a /CR parameter, but I need a more

What do you mean by this? Your code is just looking for a command line switch. It shouldn't care about the path that the thing was launched from.
KreativeKai wrote: In the past I've pointed shortcuts to the setup.exe file in the location we

Why are you putting the /CR on the Setup.exe command line?? You didn't write Setup.exe and it won't pass on parameters, so what's the point here??

We are using clickonce deployment and yes, I agree this limits control. Setup.exe is not passing the parms, and like you said it basically shouldn't. The only exe that I have found to read the parms passed is when I use the random address they create on the fly.
Frustrating... The clickonce deployment gives you so many advantages but in turn takes the flexibility out of the process.
Oh well, I've already started coding the first app to call the second app, and I'll have to write and read a file to pass the information between the two and also keep the clickonce setup intact.
Thanks as always for your input...

Why are you even concerned about the path ClickOnce uses at all?? Are you saying that you have two applications where one launches the second and passes command line args?? ClickOnce was not designed for that at all. It was designed for simpler, single applications only. I suggest you don't use it at all because your requirements have outgrown the capabilities of ClickOnce.
If you package your applications using traditional MSI installers, your apps get installed under Program Files and you control the names of the folders used under that.
BTW, Command$ is the old VB6 way of doing it. VB.NET uses something more standardized:
Public Sub Main(ByVal args() As String)
You get the command line arguments already parsed for you in an array of strings.

Thanks for the BTW about the VB6 code... I found it on google and didn't realize.
I agree, my requirements have outgrown the capabilities of ClickOnce...
You asked:
Why are you even concerned about the path ClickOnce uses at all??
Basically what I found was if I pass the /CR parm into the app using:
1) The long random ClickOnce path - It works
2) The shortcut ...appref-ms /CR - It doesn't work
3) Published path setup.exe /CR - It doesn't work, and you explained this earlier, which makes sense why it does not...
4) Published path appname.application /CR - It doesn't work, and is probably for the same reason that setup.exe doesn't work.
All four ways start the program, but only #1 recognizes the parm? This is where my confusion is.
I'm just confused as to if I get the command line code working, which way can I execute the application.... or maybe command line parameters are best used when the application is not click once, which is sort of what you mentioned in an earlier thread.
Thanks for all your help so far, and hopefully this will clarify my confusion.

You have to learn why things work in Windows as well as how.
1) It works because you told Windows where to find the .exe you want to launch.
2) Shortcuts do not pass parameters to the command lines they launch.
In order for you to just click Start -> Run and type your app name, hit Enter and it launches, you have to include the path to your .EXE file in the PATH environment variable. (This is something inherited from the old DOS days.) You can't do that from ClickOnce AFAIK. You have to do it using a traditional MSI installer.
Good Luck!

I enjoyed the "old DOS days" and still have several DOS manuals on my bookshelf that come in handy once in a while. My problem is that my job responsibilities are 90% COBOL code and mainframe programming and only 10% of the time I can code in Visual Studio. When I do get a chance to work in VB, it sometimes becomes more trial and error.
Thanks for your help and enjoy your weekend!

I am not sure if this helps you, but I did find a way to accept parameters when launching a clickonce application. I activated the app by creating a new process using the uri to to the *.application file appending my arguments in the query string.
I am using VB10, I don't know if it will be the same for you if you are using something different.
From My Project -> Publish (tab) -> Options (button) -> Manifests
"Block application from being activated via a URL" should be UNchecked
"Allow URL parameters to be passed to application" should be checked
After you publish like that you can launch the other app by url including a query string (http://MyDomain.com/MyFolder/MyApp.application?MyParamValueA=1&MyParamValueB=2):
When the application is launched this way the query string arguments will not appear with the regular command line arguments, but instead need to be pulled from .Net like this (make sure you add null checks):
System.AppDomain.CurrentDomain.SetupInformation.ActivationArguments.ActivationData(0)
