objective c - Clip part of the page of PDF while drawing in iOS -

July 15, 2011

I am riding the drawar method more to attract a specific page of PDF. How can I clear a part of the page and show it to me.

  - (zero) drawer: Contents in (Layered *) layer: (CGCTXTF) reference {CGContextSetRGBFillColor (Reference, 1.0F, 1.0F, 1.0F, 1.0F); // White CGContextFillRect (reference, CGContextGetClipBoundingBox (reference)); // fill out CGContextTranslateCTM (reference, 0.0f, self.bound.edight.height); CGContextScaleCTM (Reference, 1.0 F, -1.0F); CGContextConcatCTM (context, CGPDFPageGetDrawingTransform (_PDFPageRef, kCGPDFCropBox, self.bounds, 0, truth)); CGContextDrawPDFPage (Reference, _PDFPageRef); }   If you set a clipping area on you, you can set one part of the page The clip can reference the PDF page before referencing.

ToBoolean (value); If (isAllAccess) {for (ii = 0; i & lt; RadGrid2.VisibleRowCount; i ++) {ASPxCheckBox chk = RadGrid2.FindRowCellTemplateControl (I, blank, "checkbox 1") as ASPxCheckBox; Chk.Checked = True; Chk.Attributes.Add ("Check", "Check"); }} And {// Other stuff}}    I can only get the price which is only checking the problem, checking the check box, Did "try to add a feature but still nothing happens. any idea?

firebird2.5 - What is the use of firebird.msg in firebird database -



    I'm thinking of using Firebird with my application. I would like to know that the  firebird.msg  is used for the file. Is it an optional or compulsory file to include in your app installer package?       firebird.msg  contains firebird's actual error messages when an error occurs , Firebird only sends the error code and message parameters. The client library then sees the actual error message text in this file.   Without the presence of this file (for firebird 2.5 and earlier its in a folder for  fbclient.dll  (or similar libraries), Firebird 3 and later the same folder In) errormessage will only report that it can not get the  firebird.msg  and error number.   So you do not really need it, but if you need firebird clients or embedded libraries or want and if you want or want a meaningful error message from the firebird, then you should include it.

My idea is to first set the width of the table in the inner width of the wrapping divis, that I can do this with something like    $ ('# objects'). Width ($ ('# Object') .Parent (.) Width ()); Second, it is my goal that to display some columns per line, depending on the width of the row   My questions:    Is my planned way of accomplishing this by sending the width of the table as the parameter of the javasc
