Hello Bylka,

Did you try using a simple project shipped with CVI?

C:\Users\Public\Documents\National Instruments\CVI\Samples\Vision\1. Getting Started

have a nice day,

Hello
yes I have already seen the example but in my case I want to use the function  imaqReadFile  while taking as a parameter not an image but an array of images with the name of the folder where my images are
thank you

Ok thank you Bylka.

In that case, why don't you use a for loop with the array of images in input and the imaqreadfile inside the for loop? This way you can create an array of reference with all the pictures.

Thanks

Hello M-Junior, thank you for answering me

at begining i do this and its work without error

    /* Create all global images */
    for ( i = 0; i < NUM_OCR_IMAGES; i++ ) {
        ocrImagesArray[i] = imaqCreateImage (IMAQ_IMAGE_U8, 10);

    /* Load all the OCR images */
    imaqReadFile( ocrImagesArray[0], "OCR\\Image 00.bmp", NULL, NULL);
    imaqReadFile( ocrImagesArray[1], "OCR\\Image 01.bmp", NULL, NULL);
    imaqReadFile( ocrImagesArray[2], "OCR\\Image 02.bmp", NULL, NULL);
    imaqReadFile( ocrImagesArray[3], "OCR\\Image 03.bmp", NULL, NULL);
    imaqReadFile( ocrImagesArray[4], "OCR\\Image 04.bmp", NULL, NULL);
    imaqReadFile( ocrImagesArray[5], "OCR\\Image 05.bmp", NULL, NULL);
    imaqReadFile( ocrImagesArray[6], "OCR\\Image 06.bmp", NULL, NULL);
    imaqReadFile( ocrImagesArray[7], "OCR\\Image 07.bmp", NULL, NULL);
    imaqReadFile( ocrImagesArray[8], "OCR\\Image 08.bmp", NULL, NULL);
  }

all images on this file its shown on my interface

but when i try to do somthink lik standar without mentioning all the photos on my folder like this

for ( i = 0; i < NUM_OCR_IMAGES; i++ ) {
        ocrImagesArray[i] = imaqCreateImage (IMAQ_IMAGE_U8, 10);
    /* Load all the OCR images */
    imaqReadFile( ocrImagesArray[i], "OCR\\Image 0.%d.bmp", NULL, NULL);

}

i have error

NON-FATAL RUN-TIME ERROR:   "OCR.c", line 118, col 5, thread id 4004:   Function imaqReadFile: (errorCode == -1074395995 [0xbff604a5]). File not found.

i dont know what i can make here that my code understands that they have to take the photos found in the OCR folder;

imaqReadFile( ocrImagesArray[i], "OCR\\...............bmp", NULL, NULL);

thks for help

    for ( i = 0; i < NUM_OCR_IMAGES; i++ )  
    Hello

i do this modification and it's work
        ocrImagesArray[i] = imaqCreateImage (IMAQ_IMAGE_U8, 10);
        for (r=0; r <10; r++)   {
    sprintf(nom, "OCR\\Image %02hu.bmp", r);
    printf("nom=[%s]\n", nom);          
    imaqReadFile( ocrImagesArray[r], nom, NULL, NULL);
