    Hi @shod90 

    As per my understanding, you are trying to read the data using OCR and the output is OCRText.

     

    use loop condition and or for each activity 

    then loop through the item

    then use If condition and 

    give the Vraible OCRText in the first operand and then is not empty as shown below image.

    Hope this helps,

    Usha.

    Please find the solution.

    VishnuReddy1997_0-1718339683048.png

    Code:

    Please copy and paste this code to your flow.

    OCR.ExtractTextWithOCR.ExtractTextFromScreenWithWindowsOcr WindowsOcrLanguage: OCR.WindowsOcrLanguage.English ImageWidthMultiplier: 1 ImageHeightMultiplier: 1 OcrText=> OcrText
LOOP WHILE (True) = (True)
 IF IsNotEmpty(OcrText) THEN
 EXIT LOOP
 END
 OCR.ExtractTextWithOCR.ExtractTextFromScreenWithWindowsOcr WindowsOcrLanguage: OCR.WindowsOcrLanguage.English ImageWidthMultiplier: 1 ImageHeightMultiplier: 1 OcrText=> OcrText
END

    I don't know why this flow not working for me , This flow should exit the loop if it's found a text inOCRtext , Right ?

    Actually on my pc on both cases it exits !

    Hi @shod90 ,

     

    The OCRText variable may contain Voidspaces.So just use trim text as shown in below image.

    VishnuReddy1997_0-1718599308920.png

     

    Code:

    OCR.ExtractTextWithOCR.ExtractTextFromScreenWithWindowsOcr WindowsOcrLanguage: OCR.WindowsOcrLanguage.English ImageWidthMultiplier: 1 ImageHeightMultiplier: 1 OcrText=> OcrText
Text.Trim Text: OcrText TrimOption: Text.TrimOption.Both TrimmedText=> TrimmedText
LOOP WHILE (True) = (True)
 IF IsNotEmpty(OcrText) THEN
 EXIT LOOP
 END
 OCR.ExtractTextWithOCR.ExtractTextFromScreenWithWindowsOcr WindowsOcrLanguage: OCR.WindowsOcrLanguage.English ImageWidthMultiplier: 1 ImageHeightMultiplier: 1 OcrText=> OcrText
 Text.Trim Text: OcrText TrimOption: Text.TrimOption.Both TrimmedText=> TrimmedText
END

    Please follow the below flow for contains approach:

     

    In the below flow, I have included variable called SearchText to mention your text or char to check in the extracted OCRTEXT and also i have added messagebox to display ocr text before goes into if condition so that it will give some idea on what is being extracted through OCR on each time extraction.

     

    Deenuji_0-1718614142520.png

    You can declare variable like searchtext and use that variable in if condition second operand like below.

     

    Deenuji_1-1718614202535.png

     

     

    Code:

     

    SET SearchText TO $'''Power'''
OCR.ExtractTextWithOCR.ExtractTextFromScreenWithWindowsOcr WindowsOcrLanguage: OCR.WindowsOcrLanguage.English ImageWidthMultiplier: 1 ImageHeightMultiplier: 1 OcrText=> OcrText
Text.Trim Text: OcrText TrimOption: Text.TrimOption.Both TrimmedText=> TrimmedText
LOOP WHILE (True) = (True)
 Display.ShowMessageDialog.ShowMessage Title: $'''Info''' Message: $'''Extracted Text: %OcrText%''' Icon: Display.Icon.None Buttons: Display.Buttons.OK DefaultButton: Display.DefaultButton.Button1 IsTopMost: False ButtonPressed=> ButtonPressed
 IF Contains(OcrText, SearchText, True) THEN
 EXIT LOOP
 END
 OCR.ExtractTextWithOCR.ExtractTextFromScreenWithWindowsOcr WindowsOcrLanguage: OCR.WindowsOcrLanguage.English ImageWidthMultiplier: 1 ImageHeightMultiplier: 1 OcrText=> OcrText
 Text.Trim Text: OcrText TrimOption: Text.TrimOption.Both TrimmedText=> TrimmedText
END
