Many developers face compatibility issues when transitioning from 32-bit to 64-bit applications, especially when working with older versions of libraries and SDKs. One such case involves the PDF2TXT SDK, which was originally designed to run in a 32-bit environment. However, modern software development often necessitates the use of 64-bit applications. Fortunately, the PDF2TXT DLL Library is fully compatible with 64-bit programs. This article will guide you through the process of calling the PDF2TXT SDK DLL from a 64-bit application, ensuring smooth and efficient integration.

✅ Steps to Use PDF2TXT COM from Both 32-bit and 64-bit Applications
The PDF2TXT SDK package includes a file named `PDF2TXTCOM.exe`. Follow these steps to use the PDF2TXT COM component from both 32-bit and 64-bit applications:
1. Register PDF2TXTCOM.exe
To register the `PDF2TXTCOM.exe` into your system, you need to run the following command line with administrator privileges:
```sh
PDF2TXTCOM.exe /regserver
```
2. Call PDF2TXTCOM.exe from a 64-bit Application Using VBScript
You can use the following VBScript (VBS) to call `PDF2TXTCOM.exe` from your 64-bit application. This script demonstrates how to set various options and convert a PDF to text.
VBScript Example
```vb
Dim oTest
Dim nRet
Set fso = CreateObject("Scripting.FileSystemObject")
strFolder = fso.GetParentFolderName(wscript.ScriptFullName)
destinationPath = strFolder & "\verypdf.pdf"
Set oTest = CreateObject("PDF2TXTCOM.PDF2TXT")
oTest.com_SetTXTFormat 1
oTest.com_SetZoomRatio 90
oTest.com_PDF2TXTSetLicenseCode("XXXXXXXXXXXXXXXXXXXXXX")
nRet = oTest.com_Pdf2Txt(strFolder & "\sample1.pdf", strFolder & "\sample1-pdf2txt.txt")
nRet = oTest.com_Pdf2TxtEx(strFolder & "\sample1.pdf", strFolder & "\sample1-pdf2txtEx.txt", 0, 0, "", "")
MsgBox "Convert Success!"
```
Explanation
1. Create Object: The script creates an instance of the PDF2TXTCOM object.
2. Set Options: It sets various options such as the text format and zoom ratio.
3. Set License Code: You need to set the license code for the PDF2TXT component.
4. Convert PDF: The script converts the PDF to a text file using two different methods (`com_Pdf2Txt` and `com_Pdf2TxtEx`).
5. Success Message: Upon successful conversion, a message box is displayed.
✅ Conclusion
By following the steps outlined above, you can successfully call the PDF2TXT DLL Library from a 64-bit application. Registering the `PDF2TXTCOM.exe` and using VBScript to interface with the COM component ensures compatibility and allows for seamless PDF to text conversion in your applications.
