Issue Attaching Raster image in Microstation MDL V.8.05-2004

Hello,

I;m trying to attach a raster image to a file but I'm not sure what I'm doing is correct or not. So, I started with basics and developing slowly.

So, first I tried to attach the raster to active model. This works fine but there is something that I noticed is that I need to open raster manager then run my app to attach the image. This is what I have and it worked for adding raster to active model:

int main(int argc, char *argv[])
{
    long rasterHandle;
    RasterExtendedInfo extendedInfo;
    
    if(mdlRaster_fileOpen (&rasterHandle, "c:\\temp\\38O17Q14.tif", mdlModelRef_getActive(), FILE_ACCESSMODE_READ, EVENT_UPDATE)==SUCCESS){
        mdlDialog_openInfoBox("Raster attached successfully");
    }
    
    
    mdlRaster_renderingInfoGet(&renderingInfo,rasterHandle);
    renderingInfo.view1=1;
    mdlRaster_renderingInfoSet(&renderingInfo,rasterHandle,EVENT_UPDATE);        
    
    mdlState_startDefaultCommand();
    mdlSystem_exit(NULL, 1);
    return 0;
}

Do I need to change any part of this code so that I don't need to open raster manager and then run the app?

I will then tried to attach raster image to another file that is not open but I'm failing to do so. I tried to open the file or create the file and reference that file for attaching raster image but neither worked.

nt main(int argc, char *argv[])
{
    long rasterHandle;
    RasterExtendedInfo extendedInfo;
    
    //open an exiting DGN file
    /* if(mdlWorkDgn_openFile(&pModelRef, &pFormat, FALSE, "c:\\temp\\test.dgn", NULL, FALSE)==SUCCESS){
        mdlDialog_openInfoBox("WorkDgn opened successfully");
    } */
    //create new DGN file
    if(mdlWorkDgn_createFile(&pModelRef, "c:\\temp\\test.dgn", pFormat, MASTERFILE, SEED_CopyTCB, NULL, NULL, FALSE)==SUCCESS){
        mdlDialog_openInfoBox("WorkDgn created successfully");
    }
    mdlRaster_initialize();
    
    //command bellow returns SUCCESS 
    if(mdlRaster_fileOpen(&rasterHandle, "c:\\temp\\38O17Q14.tif", &pModelRef, FILE_ACCESSMODE_READ, EVENT_UPDATE)==SUCCESS){
        mdlDialog_openInfoBox("Raster added successfully");
    }
    
    //This part should be responsible for displaying raster on the model but need to figure out how to apply this to the file referenced above
    mdlRaster_renderingInfoGet(&renderingInfo,rasterHandle);
    renderingInfo.view1=1;
    mdlRaster_renderingInfoSet(&renderingInfo,rasterHandle,EVENT_UPDATE);
    
    
    mdlWorkDgn_saveChanges (pModelRef);
    mdlWorkDgn_closeFile(pModelRef);
    
    mdlState_startDefaultCommand();
    mdlSystem_exit(NULL, 1);
    return 0;
}

Ideally, I want to be able to attach raster to multiple files without having to do it one by one. Can you guide me on how I can achieve that? Is element descriptor a fine approach for this task?

Regards,

Mo
