StringLoader::LoadLC Problem

[r.madhusudanan]

Hi friends

I need to pass a dynamic value during runtime in StringLoader::LoadLC();
When i use a static variable like

TInt getText = R_COMMAND1_TEXT;

and pass to

HBufC* textValue = StringLoader::LoadLC(getText );

Then its working fine.I can get the value.

But my problem is, i need to pass a value which i get it in TBuf variable.
I tried to convert the TBuf to TInt and tried to pass the value.
But the application get crashed.

Can any one please help me to solve this problem.
The code i tried is ...

_LIT(KgetText,"R_COMMAND1_TEXT;");
TBuf16<50> To_Print1(KgetText);
TInt ddd;
TLex iLex2(To_Print1);
iLex2.Val(ddd);
HBufC* textValue = StringLoader::LoadLC(ddd);

Wats the problem in this .....

could you explain what is the purpose of this ?

R_COMMAND1_TEXT is mapped to a interger that defines the resource, thus you need to use it as interger directly as with the working sample code you showed.

Hi

My purpose is to get the value from a .rss file where i have stored as a resource.

During runtime i need to get the resource value.

I have value in a TBuf variable. According to the value i need to retrieve the value from the resource.

May I ask what "value" you need?
R_COMMAND1_TEXT is a number, #define-d in your .rsg file, that is a value.
textValue is a buffer, loaded from your resource file, that is an other value.
And there is no 3rd "value" I can imagine.

TInt ddd=R_COMMAND1_TEXT;

is what you are looking for?

[r.madhusudanan]

so then how can i get the resource value in runtime ?

Is there some other way so that i can get the resource value using a TBuf variable apart from TInt ?

This should also be a lesson in checking return code for errors.
No doubt iLex2.Val(ddd) is failing and you are not checking it.

But as Wizard says, if you look up the definition of R_COMMAND1_TEXT in the RSG file you will see that it is just a #define to a number already.

The string "R_COMMAND1_TEXT" is not present in your running application by default. If you need recognizing it in runtime, you have to provide your own converter-method (a series of if-s for example). I still can not see the point anyway.
