    copied!<p>My PROJECT gives error..</p> <blockquote> <p>*Unable to find an entry point named 'gsapi_new_instance' in DLL 'gsdll32.dll'.*</p> </blockquote> <p>when trying to convert .pdf to image format using Ghost-script Interpreter dll 'gsdll32.dll'</p> <p>Even if I tried copying this dll to all desired places as told in many forums like in </p> <p>Win\System32 or in The project's directory..The error remains the same..:(</p> <p>I have used The PDFConvert.cs class given by Ghost-script and written the following code on my Convert Button click:</p> <pre><code>private void btnConvert_Click(object sender, RoutedEventArgs e) { //First We Check whether the Dll is present if (!File.Exists(AppDomain.CurrentDomain.BaseDirectory + "\\gsdll32.dll")) { MessageBox.Show("The library 'gsdll32.dll' required to run this program is not present! download GhostScript and copy \"gsdll32.dll\" to this program directory"); return; } if (string.IsNullOrEmpty(txtSingleFile.Text)) { MessageBox.Show("Enter the File name"); txtSingleFile.Focus(); return; } else if (!File.Exists(txtSingleFile.Text)) { MessageBox.Show("The File Does not exists"); txtSingleFile.Focus(); } else ConvertPdfToImage(txtSingleFile.Text); } </code></pre> <p>and My ConvertPdfToImage Method is as like: </p> <pre><code>//The Ghost-Script Class Object Creation: PdfToImage.PDFConvert converter = new PdfToImage.PDFConvert(); public void ConvertPdfToImage(string filename) { //bool converted = false; System.IO.FileInfo input = new FileInfo(filename); string outPut = string.Format("{0}\\{1}{2}", input.DirectoryName, input.Name, txtExtensionName.Text); converter.OutputFormat = txtExtensionName.Text; outPut = outPut.Replace(txtExtensionName.Text, string.Format("{1}{0}", txtExtensionName.Text, DateTime.Now.Ticks)); converter.Convert(input.FullName, outPut); lblConvertingResult.Content = string.Format("{0}:File Converted..!!", DateTime.Now.ToShortTimeString()); } </code></pre> <p>i believe This error comes because of the Misplacement of gsdll32.dll library because the same code runs well with the sample demo Provided By the Ghost-Script Interpreter API.. Please Suggest The exact Location where I shuld Keep the dll-gsdll32.dll.!!</p>
