Calculated Control in Access -


मेरे पास एक साधारण तालिका है 

  अनुबंध # ग्राहक # aaa111 123 bbb222 453 ccc333 232 ddd444 23X

जब मैं इसे एक रिपोर्ट के रूप में लाता हूं, मुझे शीर्ष लेख में कुछ गणना वाली फ़िरर्ड्स लेना है, जो ग्राहकों की संख्या और संविदाओं की संख्या की गणना करेगा। लेकिन जब मैं एक रिपोर्ट और टाइप = गणना ([ग्राहक #]) और = गणना (अनुबंध #)) को एक टेक्स्ट बॉक्स के नियंत्रण स्रोत में बनाऊँ तो मुझे एक त्रुटि मिलती है रिपोर्ट व्यू में यह एक वाक्य रचना एक प्रपत्र पर काम करता है, लेकिन रिपोर्ट नहीं है यह एक रिपोर्ट में क्यों काम नहीं करेगा?

धन्यवाद।

Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
