Then it is not necessary at all to start that command with a "cmd.exe ..." call. Just call the application you need, e.g. process.StartInfo.FileName = Winword.exe

Since that I have created about 15 separate libraries for the main exe, they are in the same folder as exe.
I was thinking of putting those class libraries (DLLs) into a folder called "Libraries" in the main exe folder, so that the directory will look cleaner and organized.
How can I do that so that the exe file can load libraries from "Libraries" folder?
I'm using Visual Studio 2010 Premium.

To load an assembly from a specified subdirectory of the application's base directory requires a modification to the configuration file.
e.g.
<configuration>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<probing privatePath="Libraries"/>
</assemblyBinding>
</runtime>
</configuration>
See probing element[^] at msdn.
The Assembly Fusion log viewer[^] will show all paths searched during assembly loading and is a useful tool to have running, especially if you make a mess of editing the config file. It's helped me out more than once!

Hello. I'm streaming a webcam using DirectShow. I can open the camera fine on a windows form once. But, If I close the camera and then try to reopen it my code fails on the RenderStream line. Once I restart my application everything is fine again. I'm quite certain I'm freeing everything up, but i'm stumped. Any help would be GREATLY appreciated.

What is the exception that it throws?

Thanks for replying. capGraph.RenderStreamdoesn't throw an exception, but it returns -2147024809
|
|
|
|
|
|
OK. It tells me parameter is incorrect. That's the exception thrown. Which leads to believe the one of my two IBaseFilters isn't being released. But I don't see where or how.
|
|
|
|

if (grabberBase != null) Why's that there? It should not be disposed before the ReleaseComObject is called.

Hi there,
I need to determine the view permission group(s) from DFS link objects. I couldn't find any advices at all.
Background: We need a tool for billing our used share space. The code for our cost centers is stored in the associated user group objects shown under Properties -> Advanced -> "Configure View permissions" in DFS Management Console.
Any idea will be welcome, WMI, WinAPI Marshalling - whatever...
Thanks a lot
Roland

I really don't know where to find fault here. So I published this application and tried to run the setup file. Cannot Start Application message box appears and the following is the error.
Quote: ERROR DETAILS
Following errors were detected during this operation.

What value does not fall within expected range? I really don't get it and am left quite clueless. I really appreciate it if someone can give me some hints.

Trouble is, it could be anything: My code will throw ArgumentException errors when one of my routines checks it's parameters and finds it to be invalid - so it could be system code that throws it, or yours.
Start by looking at your setup app, and see if you throw the exception in your code there. otherwise, you are down to adding try-catch blocks to your code in the setup to try and work out where the problem is coming from.
Not a lot we can do to help, I'm afraid.

It is strange. I tried to publish the backed up project file I had saved elsewhere in a different directory and it can be published successfully without this problem! So I copy the whole project folder to my current working directory, replace the existing one, build and publish .. the problem remains. What is that?
I've set my references to Copy Local True.
I'm sure it is not my codes. I have enough try and catch blocks and there is no error or warnings.

hi friends,
If you are the POS developer you'd know that if the customer want to pay using EFT I have to have hardware and banking connection over the wire.
How do I make my POS application accept EFT payments?
Are there 3rd party tools that does it?
Are there any FREE 3rd part tools for it?
I was wondering are those 3rd party components provide an API to their .DLLs so that I could program it?
PS- Im using winApps with C# but I have not used MS POS libraries so far
thanks

You would need to find a bank transaction processing company in your area THAT YOU TRUST(!!) to handle the payments for you.
NONE of them are free.
|
|

|

To add to what Dave said: Never, ever, accept code from a insecure website to handle anything to do with real money.
You do not know who is giving you the code, you do not know what it does, you do not know that it places the monies correctly into the appropriate account, without passing the details to any third parties.
Only get such code from reputable card transaction service companies - the scope for fraud otherwise is far too large. And remember, you personally could be liable for any monies lost if your action is seen to be negligent - which getting your code from a public forum would most certainly be!
Would I trust a free API? Well, let me put it this way: would you trust me with your bank account details?

I've downvoted you. It's not personal but I think your remark is wrong;
First, he did not state that one should be careful when using "open source". You might mean "free software", but that's not the same as open source software.
Second, there is no way that an assembly that comes without sourcecode is "more trustworthy" than anything that comes with sourcecode. That is not logical.
