Hi All,

Please see the attached QVW file, where i am trying to add some images.

Req,test and defect values has specific images and i want to attach these specific images to specific data.

In attached QVW file only one (wrong) image is displayed for defect.

How can all images with correct data can be displayed?

Thanks in advance

Hello

You need to change your expression for the Image to =Info(Tab), when I did this it gave me blank lines rather than an expression in the cells but I'm not sure if this means the images are not there.

Just for your peace of mind I have attached the same sort of thing that certainly works for me, as you'll see from the currency symbols on the table.

Hope it helps,

Thanks QVCON for the reply.

This the problem that it is displaying one image only.

Do you want me to send other image and data file?

Thanks

Hello Mansi!

I have seen you document but not able to understand what you are doing there. Why don't you use the below expression to display the image.

<pre>if(Sum(SalValue) - before(Sum(SalValue)) < 0,'F:\Red.png', if(Sum(SalValue) - before(Sum(SalValue)) > 0, 'F:\Green.png','F:\Blue.png'))

// Refer http://community.qlik.com/forums/t/24170.aspx

Thanks and Regards,

Rikab

Hi Mansi

Having read the thread above, this seems like a better solution for your problem, I didn't think you could access images straight from the folders so I suggest using that solution.

One thing that I can't remember is whether I used PNG files because JPG files would not work, my solution works using PNG files and the thread above uses PNG files also, so you might want to try changing to PNG rather than JPG.

Good luck,

use the following code in the editscript dialogue of your qvw file


image:
LOAD Tab,
 I,
 rowno() as no
FROM
.....\imagetest1.txt
(txt, codepage is 1252, embedded labels, delimiter is ',', msq);

let vNo = peek('no',-1,'image'); // Get current number of image from image table field

for i=1 to $(vNo) // Go to the current number of image
Photos:
 load $(i) as no, $(i)&'_150.jpg' as Photo autogenerate(1);
next


for j=1 to $(vNo)

BUNDLE INFO LOAD * INLINE [
 Photo, Index
 $(j)_150.jpg, .....(here u write the path of the folder where you will be keeping your images)\$(j)_150.jpg
 ];

next j;
[\code]

you also need to rename your image req as 1_150, testing as 2_150 and so on as per the requirement of above code.

one constraint in the above code is that you can only open either all jpg images in your image folder at onetime or all gif images or all png images or all bmp and so on. ie the type of image should be same.
thanks

Hi,

see the attached Example.

Be sure that the "Path" is set correctly in the excel file.

Good luck!

see if you want to display image , you need to create either a listbox or a textbox

if you are creating a listbox ,clicking on the 'i' /// i stands for info /// button on topright corner of textbox will display the image.

but if you are creating a textbox,use image as representation on the general tab of textobjectproperties .

thanks dsjain.

But i don't have .png files. I need to use jpeg file in my app.

I used your method with jpeg file, but it was not displaying images.

Hi Mansi,

here are the next one using jpg.

Please use a fresh qvw file and different names (including the line headers in the excel file) if you try to rebuilt the application.

Otherwise QV will find the old pictures instead of the new ones.

Thank you so much Rainer for the reply.

i think there is a constraint that at a time only one type of image can be displayed.

Thanks Rainer,
