Image Not Showing Using Parameters

[jencendencia75]

hi.. i have a problem with crystal report. (im using visual studio 2019 / visual basic .net) i have a picture in the report with a parameter attach to it. in the windows form, when i try to preview the report, the image will not show up. i passed a value to the parameter using the code below:

myReport.SetParameterValue("paramImagePath", imagePath) 

'myReport is the instance of the report

paramImagePath is the name of the parameter in the report

'imagePath is the variable i use.

when im using a variable, the image will not show up. i checked the value of the variable many time, it is the same with the manually inputted path of the image.

but when i input the path of the image manually, like the code below :

 myReport.SetParameterValue("paramImagePath", "E:\From Drive D\VB Net Activities\BrgyPoblacion\BrgyPoblacion\Images\1.png")

the image will show up. what seems to be the problem.

please help regards.

SOLVE it.

i copied a temporary image to the debug folder, same id/or name with the image.

thanks for the help.

Issue was likely permissions....

hi thanks for the reply.. i dont really get it..

my problem is that the image will show up if i manually inputted the image location.

sample.

myReport.SetParameterValue("paramImagePath", "E:\From Drive D\VB Net Activities\BrgyPoblacion\BrgyPoblacion\Images\1.png")

but when i use a variable to set the image, like the code below

myReport.SetParameterValue("paramImagePath", imagePath) 

the image will not show up.. even though the variable has the same value with the MANULLY inputted value.

I CAN SEE THE IMAGE IF THE VALUE TO THE PATH IS MANULLY INPUTTED IN THE PARAMETER.

what seems to be the problem here?

That's not the CR image Dell was talking about.

In my Parameter test app there is this routine:

case "Graphic Location Formula":
    #region GRaphicsLocal
    btnReportObjects.Text = "";

    CrystalDecisions.ReportAppServer.ReportDefModel.ConditionFormula myGraphicLocationFormula;
    rptObjs = rptClientDoc.ReportDefController.ReportObjectController.GetReportObjectsByKind(CrReportObjectKindEnum.crReportObjectKindPicture);

    // get the count of picture objects
    btnCount.Text = rptObjs.Count.ToString();
    foreach (CrystalDecisions.ReportAppServer.ReportDefModel.PictureObject MyrptObj in rptObjs)
    {
        if (((dynamic)MyrptObj).GraphicLocationFormula.Text != null)
        {
            textBox1 = "Picture Name: " + MyrptObj.Name.ToString() + "\n";
            textBox1 += "Graphic Location Formula:     " + MyrptObj.GraphicLocationFormula.Text.ToString() + "\n";
            btnReportObjects.Text += textBox1;
            btnReportObjects.AppendText(" 'End' \n");
        }
        else
        {
            textBox1 = "Picture Name: " + MyrptObj.Name.ToString() + "\n";
            textBox1 += "Graphic Location Formula: None\n";
            btnReportObjects.Text += textBox1;
            btnReportObjects.AppendText(" 'End' \n");
        }
    }
    #endregion GRaphicsLocal
    break;

You can modify it to update the formula field that has the path in it.

You will need to set this up in the Report also.

Have you verified that imagePath has a valid value that points to the file that you want to show? Or does it just have the path to a set of image files?

hi.. thanks for your reply.. as stated above, i have checked and verified the value of the imagePath variable.. it has the same value with the manually inputted path.. for example.. the manually inputted path is

"E:\From Drive D\VB Net Activities\BrgyPoblacion\BrgyPoblacion\Images\1.png"

the value of the imagePath variable is the same (as you can see in the picture above).
