good day! :WAVE:

I'm a new member of this forum and i'm wondering if you could help me with my problem.

i currently have two programs, one in VB and another in VC++. The first one is a motion detector program that saves a picture in bitmap file whenever a camera detects movement. The other one is an mfc application that decodes a bitmap file (a 2D barcode image) and outputs the data in the file. The idea is that whenever a barcode is inserted in front of a camera, the image is saved into a file. Then the mfc should be triggered to decode that predefined file and return the value to the VB program.

Right now, I manually operate ng mfc application to decode the image file and i want to automate this. Is there a way that VB could call this mfc decoder and accept and store a bit string of data from it? I'm thinking of a boolean in the motion detector VB program. A variable will have initial value of 0. When a card (with the barcode) is inserted and movement is detected the variable is set to 1 and the VB calls the VC++ mfc to decode the image. Then the mfc should return a data which the VB program will fetch. Then after the card is withdrawn (motion detected) the variable will reset to 0.

I hope you can help me with this.

thank you very much in advance. :)
