I would add a PDF document online to a user's signature (like your signature on the credit card, for example). How can i What is the best practice for such actions?

You can use it to. This will work for you: 

  pdfReader pdfReader = null; Pdfstammer pdfstamp = faucet; // Open the PDF file to sign pdfReader = new PDF Reader (this.signFile.FullName); // To use Stripped PDF to output stream (filestream outstream = new flamestream (target filename, foilmod.creative)) {try {// a signature pdfstammer = PDF with new PDF format (pdf reader, outstream) Stammers to make tickets; // Load signature image iTextSharp.text.Image sigImg = iTextSharp.text.Image.GetInstance (SIGNATURE_IMAGE_PATH); // image scale to fit sigImg.ScaleToFit (MAX_WIDTH, MAX_HEIGHT); // Set the signature status on the page sigImg.SetAbsolutePosition (POS_X, POS_X); // Add signature to the desired page PdfContentByte = pdfStamper.GetOverContent (PAGE_NUM_TO_SIGN); Over.AddImage (sigImg); } Finally {// clean (pdfStamper! = Null) pdfStamper.Close (); If (pdfReader! = Null) pdfReader.Close (); }}

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' .

I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
