Hello,

I have a web portal with traditional webpages.

This website is enabled with multiple languages and translated text is saved/retreived from database.Website works with all languages in all pages except one page for French language.

When I click the buttons(only when current language is Fech ) in that particular page-->form's postback event is fired but no button click event.

Can somebody help me with this problem.

Inspect the page_load "sender" object in quickwatch and see if the button is missing.
Also, check the viewstate of the page.

Another probable reason could be validation request. As you gave choose culture french, there could be a possibility of having characters that are recognized as potential dangerous to restrict cross scripting attack.

Hope this helps.
cheers

Here is my code to convert pdf

//Pdfbuilder is string builder

string strPdfContent = Pdfbuilder.ToString();

Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=AboDetails.pdf");

Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringReader reader = new StringReader(strPdfContent);
Document doc = new Document(PageSize.A4, 10, 10, 0, 0);

HTMLWorker parser = new HTMLWorker(doc);
PdfWriter.GetInstance(doc, Response.OutputStream);
//PdfWriter writer = PdfWriter.GetInstance(doc, new FileStream(AboDetails.pdf, FileMode.Create));

doc.Open();
try
{

parser.Parse(reader);

Response.Write(doc);
Response.End();
}
catch (Exception ex)
{

}
finally
{
doc.Close();

No, it's not. This is a free service, and you can't rush charity. If your planning did not include research, I suggest you review your planning.

FWIW; you first want to know whether the file is generated correctly, or not. If it is, then there's a problem in the transfer, or the viewer - otherwise you could quickly try another PDF-generator.

Easiest way to determine is by generating the PDF on the server, copying the PDF by hand, and try to open it on different computers with different viewers (I use both the Adobe-reader and the Foxit reader to verify) Also try to find out the version of the PDF file being generated.

Hi every one.
I have copying my database via setup to Program File of customer system.
now how can i give the conection string that can attach the DB (in webconfig):

<connectionStrings>
    <add name="SqlConnStr" connectionString="Data Source=.\CMSNegin;AttachDbFilename=%programfiles%\TSMS.mdf;Initial Catalog=NeginDB;uid=sa;pwd=u1$%^ggrf0923" providerName="System.Data.SqlClient"/>
   
  </connectionStrings>

I have used "%ProgramFiles%" but no use...

Please Help

Thanks in Advanced !

If you use values like this in your connection string then i think you will need to modify it at execution time in order to replace the %programfiles% with the real path. See Web.config File - ASP.NET[^] for some useful information on the web.config file.

You need to spend some time getting familiar with MSDN, which contains documentation for just about everything you will ever need, including this section on environment variables[^].

The link to the documentation that I posted contains a code sample, I cannot offer anything that is clearer than that.

You have the solution, it's just that you need to to spend some time modifying it so it suits your specific problem.

There is really no point in you repeatedly posting the same cry. I have given you a link to the method you need to use, which includes a code sample which demonstrates exactly how it can be used to expand an environment variable in a string. Unless you give some more details about how exactly you are trying to use it and why it does not work, then it is unlikely that we can guess what your problem is.

Hi sir,
this is exactly what i wanna to use in webconfig:

<connectionStrings>
    <add name="SqlConnStr" connectionString="Data Source=.\CMSNegin;AttachDbFilename=%ProgramFiles%\CMSNegin\Data\MSSQL10.CMSNegin\MSSQL\DATA\1\NeginDB.mdf;uid=sa;pwd=A@D#F$G%" providerName="System.Data.SqlClient"/>

  </connectionStrings>

i dont know which drive is system drive (C or D).cause my setup copies the database to %programfiles% .
may be C:\program files OR D:\Program files.

I still don't understand what your problem is. If you follow the documentation in the link I gave you[^], it shows exactly how to get the real path from an environment variable, including the system drive. What more do you need?

I think this is what your looking for.

Your example makes no sense to me, and I don't see the point of it. If your sql server is loaded on your hard drive, why not use the standard connection string?

As far as using a programmable path like %ProgramFiles%, that's a Windows thing, which works in certain scripting languages and the cmd prompt. I don't think the application that reads the web.config file is smart enough to translate %ProgramFiles% to the proper file path, and if it did, you need to see if it adds the final slash to the end of the path.

You still have to code the database name to make it work. Since it's on your hard drive, a trusted connection should work fine.

Server=.\SQLExpress;AttachDbFilename=c:\asd\qwe\mydbfile.mdf;Database=dbname;
Trusted_Connection=Yes;
