Report Engine and PDF Library: Example code in C/C++ (DLL/.so)

This example program is using the VPE Report Engine DLL.

With the function VpeOpenDoc() a new document is created and a handle for the document is returned. This handle is used in the following code, to access the document.

The function VpePicture inserts an image, four coordinates are supplied: (left, top, right, bottom). The parameter "VFREE" instructs VPE to compute the given coordinate for a text or image itself.

With VpeWriteDoc the document is written by the integrated PDF Library as PDF file, and finally the call to the function VpePreviewDoc shows the preview window.

void CreateDocument()
{
VpeHandle hReport;
hReport = VpeOpenDoc(hWndParent, "Tutorial", 0);
VpePrint(hReport, 1.5, 1, "Hello World!");
VpePicture(hReport, 1.5, 2, VFREE, VFREE, "example.jpg");
VpeWriteDoc(hReport, "My Document.pdf");
VpePreviewDoc(hReport, NULL, VPE_SHOW_NORMAL);
}

bullet Customer's Responses

"I must say that it [VPE] was the easiest to implement of any toolkit I have ever purchased. In addition, everything that I have used actually works. It is amazing to me how many toolkits out there don't do what they are supposed to do and probably never will."
