VB Program Fails To Run On Specific Machine?

Mar 12, 2012

Frustration has officially set in. This is my first post here, and to be very honest, I'll admit that I'm a newbie VB programmer as well. I guess that's why I'm posting here, in hopes you super-porgrammer types might be able to help.

I've written a smallish VB program with 2010 express... the code uses some text files to gather various lists of numbers ( as part of a manufacturing Bill of Material ) that assiciate to PDF files of the same name. The intent was simply to view and print the gathered existing PDF files.

I have the program mostly working the way I want ( at home ), but when I bring it to work, it fails to open.

My home PC is a 32Bit Windows Vista Machine with Adobe 10.1 viewer installed.My Work PC is a 64 Bit Windows 7 Machine also with Adobe 10.1. I've sent the .sln and code to a buddy who is also running a 64bit Win 7 machine very similar to what I have... he is able to run the program. I've sent the same thing to my work pc and tried to run it. I get some crazy HRESULT error I can't make heads or tails out of... remember I'm a newbie.

I will happily post code if you guys are interested, but I believe that it isn't code related. What kind of things MIGHT i try to look for on my work pc that would cause this simple program Not to function? I've brought other programs I've written to work without problem. But this one has me stumped.

Other things I've tried:
1) uninstall and re-install Adobe... ( no change )
2) written a super small adobe viewer program at work... ( works )
3) tried to comple as "any CPU", "x86", and "x64"... ( does not work )
4) bring .sln & code files to compile and run at work... ( does not work, HRESULT err )

UDPClient Class - Tie The Program To A Specific IP On The Local Machine?

Nov 28, 2011

Say a machine has two seperate IP's. I am running a little test program that connects to an outside piece of hardware that has it's own IP. I receive data from that hardware. I want the same little program assigned to the two seperate IPs on my local machine to get the same data from the hardware. How can this be done?I am receiving data just fine but I am not seeing how to tie the program to a specific IP on the local machine. As soon as I run another instance of my program, not data is received on the second instance.For example: I have a program running on a machine. I want two instances of that program, each on it's own ip

Instance 1: 192.168.1.240

Instance 2: 192.168.1.241

I want both instances to listen for data coming from 192.168.1.50

This is a generic example of what needs to happen. I need to know how to define the local IP's the UDPClient is running on.

Deployment Fails On XP Machine?

Apr 7, 2012

I have just finished my application using VB in Visual Studio 2005 and it works fine on my Win 7 development machine. But when I install and run it on an XP machine it fails with an unhandled exception:System.Runtime.InteropServices.COMException (0x80040154): Retrieving the COM class factory for component with CLSID {E8D851FA-9967-4ADF-9644-0183B9B1EA68} failed due to the following error: 80040154.

I've googled the error message and the solutions seem to be 1) compile as x86 (was doing that anyway), and 2) register the dll on the machine But firstly I'm not sure which dll I need to register, and secondly I don't want to be going around registering dlls - the whole point of the installation programs is that it should just install and configure everything automatically..

SMTP Email Client Fails On Local Machine Needs To Run On Client

Jun 29, 2010

I have an application that takes a series of reports and sends them as attachments in an email to a specified group of email accounts.

When I run the Java version of this using apache commons and the same setting, the email is sent. However, when I run the VB.NET version of the code, it fails on my local machine and on the client machine.

I have a VB.NET web application running on a server that uses similar code. I tried that code locally and it fails. Yet, the web application is working perfectly.

Why is it that the Java application can send the email, but the .NET application cannot?[code]....

Program Silently Fails During For Next Loop

Mar 17, 2012

I have this function for removing duplicates in arrays[code]...

What is happening at the moment is that the inner loop reaches the array.Remove(inner_element) line for the first time in its second loop during the second loop of the main foreach, reaches the inner next line and then just stops executing. There are no warnings / notices, the debugging step though just ends as if there was no further logic.

After Converstion Of 6 With Label Arrays To 2010 Program Fails With Stack Overflow?

Jan 12, 2011

Now I see that VB tells me that label arrays are no longer supported But I also see that VB2010 is providing the relevant logic to update each of the label array fields I was until today using VB2008, because after running this application it crashes with a report of stack overflow, I assume it is related to the label arrays, but have no idea. So I have upgraded to VB2010.

In VB2010, I note that the immediate window is reporting A first chance exception of type 'System.InvalidCastException' occurred in Microsoft.VisualBasic.dll Now I have used label arrays for showing columns of like data, generated by a for loop. What should I be using it its place, maybe a grid..

Closing Machine After Program Has Run

Feb 3, 2010

is there "rules" as to how to close programs writting in vb.net(2008)? I've migrated to dot net from vb6 and have rewritten some of my programs in the new language, but I've discovered a problem, since using the new programs if you try and close the machine down (Windows XP) the pc just hangs until I use the task manager and kill my programs.

Running 32bit Compiled Program/DLL On 64bit Machine?

May 20, 2011

I have some programs written in VB2010 using functions from a DLL. I have compiled and run these programs on a 32bit XP computer and a 32bit Win7 computer and have had no problems accessing the DLL.I have published an installation of these programs and tried running the install on a 64bit Win7 machine and the installation is performed correctly. It installs the programs and copies the required DLL into the same folder. the problem is that whenever I run the software and try to access the DLL I get errors.

The error says something like:

An unhandled exception has occurred in your application. An attempt was made to load a program with an incorrect format. (Exception from HRESULT:0x8007000B)

If I click past it the software runs and all of the forms are loaded properly, but anytime in the software if I try to access the DLL I get the same error.I am declaring functions in the DLL like this:

Public Declare Function OpenDriver Lib "OP815M.DLL" (ByVal handle_Renamed As Integer) As Integer

I have also tried placing the DLL in the system32 directory and also the sysWOW64 directory and that did not help as well.I do recall that hardware drivers need to be properly signed and pass the Microsoft Logo testing. Must I get the DLLs I am using properly signed?

Edit: Also it might be fair to mention that I have used the DLL with another program written in C, which would run in the DOS command line in Windows and it correctly accesses the DLL on a 64bit machine, but just when run from the DOS command line in windows.

How VB Can Focus A Specific Program And Then Send Commands To The Program Only

Aug 3, 2011

I am trying to figure out how VB can focus a specific program and then send commands to the program only. The focus would only be for the commands and would not make the program you are currently in lose focus. Simply, what it is controlling is a Windows Application called GOM Player. I use it to study my material for school. I plays movies in it and don�t have to click out of the application I am working in to pause, play or rewind. The keypad and the company who make it actually have it built into iTunes and it does exactly what I want GOM Player to do.

The reason I dont just use iTunes is because I can�t get my video files to play in iTunes. After pulling teeth with the manufacture I finally to tell me that the iTunes functionality is accessible via plugins built into iTunes. So trying to mimic what is being done there does not help. I believe that a knowledgeable VB programmer could answer my question in seconds, but having some experience with coding and programing I know it also could be a lot more than what I think. [URL]

The question is: What is way that VB can send the key for the macro only to the GOM Player Application even if it is not focused or even If it is minimized.

Run A Program At A Specific Time?

Jan 21, 2010

I am aware that if you wish to run a program at a specific time, the best way is to add it to the windows task scheduler. I have a forms application that accepts as input a text file and some button selections before the actual main runs.
Can this kind of program be scheduled? I realize I would have to hard code the inputs but does .net have any features to access the task scheduler?
