I have a vb.net console app being executed by a sql job, however the job errors with the message ‘access denied’. The console app is located on a network server. How do I grant permissions, thus avoiding this error? Thank you,
Jason W.

Well, you have to check two things.
1) Check to see if the Windows account that the SQL job is running under has sufficient rights to the network location where the app is stored. If it's running under the Local SYSTEM account, then I guarantee that it doesn't.
2) .NET Framework apps running from a remote location (i.e. network) are not fully trusted and some functions, like writing to the file system, will throw all kinds of security errors, like Access Denied. Check to make sure that your code is running with sufficient trust. Read up on Security Policy Management[^] on MSDN for more information.

I have added the following in an attempt to resolve the error:
Dim ps As PermissionSet = New PermissionSet(PermissionState.Unrestricted)<br />
Dim sp As New SecurityPermission(PermissionState.Unrestricted)<br />
<br />
ps.AddPermission(New EnvironmentPermission(PermissionState.Unrestricted))<br />
ps.AddPermission(New UIPermission(PermissionState.Unrestricted))
Now I am receiving the following error:
Unhandled Exception: System.Security.SecurityException: <br />
Request for the permission of type System.Security.Permissions.SecurityPermission, mscorlib, Version=1.0.5000.0, <br />
Culture=neutral, PublicKeyToken=b77a5c561934e089 failed. <br />
...<br />
The state of the failed permission was: <br />
<IPermission class="System.Security.Permissions.SecurityPermission, mscorlib, Version=1.0.5000.0, <br />
Culture=neutral, PublicKeyToken=b77a5c561934e089" version="1" Flags="UnmanagedCode"/>. <br />
...
I admit at this point I am guessing as how to resolve the error. If possible I would like to put the app into unrestricted mode. I appreciate your thoughts?

Well, finish reading the link I posted yesterday and then go to Administering Security Policy[^] for a hint on how to add the correct permissions to the security zone that your app is going to be running under, since it's coming from a network share.
You can scrap the permissions code you posted. It won't work because your app can't request, and get, permissions that are denied by the security policy for the zone it's running under.

How can I add some custom controls I have created to a form at runtime ?
When the user clicks on a button, I want to add a custom panel object to the form.
I have tried something like this :
<br />
pnlTypeDeCiment = New pnlCementTypeFixed<br />
pnlTypeDeCiment.Parent() = Me.Parent<br />
pnlTypeDeCiment.SetBounds(100, 50, pnlTypeDeCiment.Width, pnlTypeDeCiment.Height)<br />
pnlTypeDeCiment.Visible() = True<br />
But without success.

Hi Leblanc,
try adding the panel to your forms Controls collection. This should work:
me.controls.add(pnlTypeDeCiment)
hope this helps.

WOuld it be feasable to instead of attempting to dynamically add controls, to add the panel at design time and then show/hide (.Visible) when necessary?

This was my first idea, but for data loading reasons I had to scrap it.
|
|
|
|
|
Data loading reasons....what might they be? Couldn't you do something like:
<br />
On ButtonClick()<br />
<br />
GetData<br />
AddToPanel<br />
ShowPanel<br />
<br />
Or am I missing the reason completely lol!

The panels contain data grids which are bounded to data on an external database. With the 3rd party library which we are using when you bound an object like this, if retreives stuff from the db automaticly which I don't want to do everytime for bandwidth reasons.
I tought that by only creating the panels when they are used I would not create a panel the user never uses and thus save bandwidth.

This is actually a Visual Studio.NET problem. When I write a Turkish character in the source code files and then close/open visual studio, the IDE changes my Turkish character to another character which is not what I want (for example when I write "Uygulaması", it becomes "Uygulamasi"). I save the source file with Turkish-ISO encoding but the problem persists.
Did you encountered a problem like this before?

Add the following meta tag, save and then try whether it works or not.

hi friends
i've got stuck about allocating one webpage into a specific frame, i do not know what system commands could be used to do so. when a user click on a link in one frame, that website should appear in other frame.
for example: i have a link button named Calendar, when the user click on this button, the calendar interface would display in the other frame.
could anyone help me please?
thanks in advance

Im using a console application because the program im working on is for automation purposes. Only problem is, i can figure out how to end the program. In a forms based program is is ME/MYBASE/THIS(C#).Close (because the program is a class) in the console its none of these. Ive tried Wrapping the API call of FreeConsole from Kernel.lib and it works only it doesnt stop the undrlying process just the window. Is there an easy way to do that that i may be overlooking?
Thanks Very much for the help.

yeah i know but i need to to prematurely quit... say on error... and im 4 functions down... and it cant just send me to an error dialog... has to print to a screen ... wait for any keypress and then terminate like a good dos program does...
|
|
|
|
|
I dont' know if this will work for you (I don't get into console apps very much), but you could try Application.Exit().

No it doesnt... if this were C# Forms or VB forms that might work, however... a console app is a module, it hasnt got a class name or functions behind it beside what it builds... id need to say get a handle of the running thread, and tell that thread to terminate...
im just not sure as to how i should do that.
Ive wrapped a few of the console APIs... FreeConsole onle destroys the window handle to the console itself... it doesnt terminate the process behind it...

Oh well, it was just a quick thought...
In that case, I'd implement a scheme as Colin suggests. Be sure it is a custom defined Exception and throw that when you need to. Make sure that the only Exception Handler that can handle that exception is the one in Main. All other exception handlers must not handle this exception if they do, must catch, then re-throw the exception to send it up the call chain back to Main.

Then throw an exception.
Create an exception class that is used for nothing else than premature exit. When you need to exit early throw the exception. Wrap everything in your main in a try/catch block and catch this specific exception. The catch handler can then process the exit in a considerate manner.
Do you want to know more?
