Crystal Report+unrecognized escape sequence

Question

Hello,

I use crystalreport in my windows application and while typing the code I got "unrecognized escape sequence"  in the path definition when loading the report. When trying to run I got "Load report failed" error.
The line for loading looks like this:

cryRpt.Load(

and I am sure the path is that.

Can anybody help me please what might be the problem?

Thanks in advance.

"F:\aer\Bl-JSPT\Bl-JSPT\CrystalReport1.rpt") 

Answer 1

I haven't used Crystal Reports for many years and don't remember much about its finer points but, in principle, I don't see why not.

If you're wanting the report to be generated automatically when the user enters something in the textbox, then you could handle its Leave event, validate the value entered and set the parameter value from there. Something like:

myReport.SetParameterValue("@myParameterDiscreteValue", textBox1.Text);

Thank you very much.

Answer 3

Thank you very much Vulpus.

Now I would like to ask you kindly one more question. Is it possible instead of entering in a separate window the discrete value (parameter value) for the report, to take it from the textbox in the form?
I have made a stored procedure and as a source I have that procedure in the crystal report. But I have an input parameter in the stored procedure, and I want that parameter to be entered by the user in the textbox in the form where the report is, not in that window that occures when the user tries to make the report. Is it possible not to have that popup window when running the form for entering the value, but taking it automatically from the textbox?

Thank you very much again.

If you put an '@' sign before the string then it should work. 

  cryRpt.Load(@"F:\aer\Bl-JSPT\Bl-JSPT\CrystalReport1.rpt");

Any escape sequences (i.e '\' followed by a character) will then be given their literal meaning rather than any special meaning they may have.
