I created a program using visual basic. For some functions the program accesses a dll which was created using visual c++. When the program is run on a computer that does not have visual studio installed, functions which make calls to the dll generate an error: Unable to load DLL 'filename.dll': This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem. (Exception from HRESULT: 0x800736B1).Reinstalling the application does not help, and when the program is run on a computer that does have visual studio installed, calls to the dll work as expected without generating any type of error.Is there some component that is installed with Visual Studio that I need to attach to my program installation? Is there some way I can create or access the dll such that it does not need this component?

View 2 RepliesI thought I had already done this in a previous project and also thought it was really easy but I am now struggling with this.All I want to do is get a list of all of the IP addresses that are assigned to the computer running my app. I thought I would use Net.NetworkInterface.GetAllNetworkInterfaces and then there would be a property on each item in that collection that told me the IPs assigned to that network card but it would seem not.
Searched and searched but the only 'solution' seems to be to use GetDnsHostEntry or WMI something similar and I dont like the sound of either of those. Surely if you can get the DNS servers IP address, Dhcp Server's IP address and Gateway IP address from the NetworkInterface instance then you must be able to get the local IP addresses as well?? I'm sure I am missing something obvious..
good database that I can use on a local machine to store names/addresses etc. and that integrates easily into .Net 2.0.I have used MySQL a fair bit, so something along that route would be great but without the need to install additional software on the computer or connect externally to a server.

View 1 RepliesI've just finished my programme, and would liek to publish it for beneficial use . But when I publish the code, only my own computer (which has Visual Basics Express 2008 Edition installed) could use the published executable file. All the other computers comes up with a warning saying a .NET environment is required.
How could I publish the codes so that the programme could run on all (or most) computers without having VB installed in all of them?
Here is my Prob- we have a main router from which we use a distributor or hub for internet connection distribution, ever computer connected automatically obtains IP address of format say - 180.50.50.xxx to access net connection.if any connected computer has different IP format than the given one, it cannot access internet.

All i want to do is simply run the program with the database from a server, and have other local computers with the program access this same database.

View 2 RepliesI'm trying to make my program compatible with more computers, even if their computer is not up to date. Im trying to make it compatible with the following windows versions, all versions so if it has home, professional, server, etc...
Windows 98
Windows 2000
Windows ME
Windows XP
Windows Vista
Windows 7 RC
Now, my program is compatible with the bottom 3, and with 64 bit computers, the problem is that my program has to have the .NET framework 3.5 installed, which meens XP needs updated and that framework installed, and on earlier versions, it wont install the framework through windows update and the like, also, I cant expect people who want to use it to have it installed, can anyone explain a way for me to make it so my program if its possible, then whatever features may use that framework, if just not calling that code will stop the program from crashing, or if i can make it use older version instead of a newer version framework, maybe only in certain cases.

View 6 RepliesI've just created a program in Visual Basic.NET 2010 Express Edition, and the program works great on my computer. Unfortunately, when I try running it on other computers, the process on the Task Manager for it comes up for literally 2 seconds and then goes away, and the program does not run. Basically, the program doesn't open. I'm not sure why this is happening, and I'm not getting any errors.
I am running Windows 7 Ultimate 64-Bit, and I've tried getting it to work on two other computers, with no luck. The first one had Windows 7 Home Premium 64-Bit, and the second one had the same operating system as my computer. All computers have the .NET Framework 4 Client Profile installed, which is what my application is compiled to work with. I also tried compiling it to use .NET Framework 4 (without the Client Profile), and that didn't help.
If it helps, my References are as follows (which I believe are the defaults):
- Microsoft.VisualBasic.PowerPacks.Vs
- System
- System.Core

From all the chat applications I successfully made each and every one of them required me to port forward my router so that the data can be received. Now my question is how can I make my chat program work on computers that have routers with most of the ports blocked, how do traditional chat programs do it? Perhaps The chat program intercepts packets then sends it to a known port such as 80?
View 17 RepliesI know how to make a setup wizard but when I install my program on other computers, I get an error (SQL Error).
What do I need to install on other computers other than .NET Framework and my program ?
I've created a multithreaded application that copies data from one directory to another, and I'm having trouble getting it to work properly on clients' computers. All computers running the software have Windows 7 and the .NET Framework 4.0 Client Profile installed, which is what I've compiled the program for. I have two threads: one does the actual copying, and the other updates the UI on the program. Whenever I run the program on my computer, even if I'm copying 45 GB, for example, it runs fine. However, if I run it on another computer, it will sometimes freeze the entire computer, so then I have to manually shut the computer down in order to use it again. I have been trying to find out why this occurs, but I cannot. Does anyone think he/she can provide me with some ideas as to why this happens and how I can prevent it from occurring?
