NET has no knowledge that it was a Terminal Services session that had the connection There's no way for those accounts to keep track of exactly which session called DebuggerLaunch Consequently, the output goes to the only real window station on the machine The good news is that if you have a debugger attached, either inside the Remote Desktop Connection window or on another machine, the call to DebuggerLaunch works exactly how you'd expect and stops in the debugger Additionally, if you make the call into the server from a browser on another machine, the call to DebuggerLaunch will not stop. vb.net pdf text extract: VB .

Encoding Images as BinHex Converting a Bitmap object to one of the commonly used image formats is a nonissue You call the Save method on the Bitmap object, pick up one of the supported formats, and you're done The real difficulty has to do with the planned use of this helper class Remember, we designed this class for later use within a NET Remoting server and a Web service When Web services in particular are involved, having the helper class save the image to persistent storage just doesn't make sense An alternative approach would be saving the bitmap locally on the server in a location accessible for download via FTP or HTTP Creating files on the server might pose security problems, however, and normally forces the system administrator to change default settings to allow for local files being created. read pdf file using itextsharp vb.net Pdf Reader in Vb . net - MSDN - Microsoft

Although it's inexcusable that Microsoft made no provisions for assertions inside ASP.NET, at least armed with AssertControl, you can start programming. If you're looking for a control to learn how to extend, AssertControl is pretty bare bones. An interesting extension to AssertControl would be to use JavaScript in the code to bring up a better UI, like a Web dialog box, to tell the user there was a problem. Listing 3-4: Important methods of ASPTraceListener public class ASPTraceListener : TraceListener { /* CODE REMOVED FOR CLARITY * / // The method that's called when an assertion failed. public override void Fail ( String Message String DetailMessage { // For reasons beyond me, it's nearly impossible to // consistently be able to get the number of items on the // stack up to the Debug.Assert. Sometimes it's 4 other // times it's 5. Unfortunately, the only way I can see // to handle this is to manually figure it out. Bummer. StackTrace StkSheez = new StackTrace ( ) ; int i = 0 ; for ( ; i < StkSheez.FrameCount ; i++ ) { MethodBase Meth = StkSheez.GetFrame(i).GetMethod ( ) ; // If nothing is returned, get out now. if ( null != Meth ) { if ( "Debug" == Meth.ReflectedType.Name ) { i++ ; break ; } } } BugslayerStackTrace Stk = new BugslayerStackTrace ( i ) ; HandleOutput ( Message , DetailMessage , Stk ) ; } /* CODE REMOVED FOR CLARITY * / 87 , ) What is a Mod 10 Number Hans P. Luhn patented a simple checksum algorithm known as the "modulus 10" or "Luhn formula" commonly used to validate certain identification numbers. Basically, the algorithm multiplies every digit in the number by a 1 or a 2 starting from the ones column and progressing leftward. If the result of a digit's computation is greater than 10, the two digits in the result are simply added together (or the result is simply subtracted by 9). The sum of all computed digits is then divided by 10. If the quotient has no remainder (sum % 10 == 0), the number passes the mod 10 algorithm. This algorithm is commonly used to verify numbers such as credit card numbers and Canadian Social Insurance Numbers. With a single input we could achieve 100 percent block and decision code coverage of the IsValidMod10Number function. A test input of 4291 would evaluate the true and false outcomes for each conditional clause and return a Boolean value of true to the calling function, which is the expected result. A second test of 1 would return false to the calling function. Both tests passed and the code coverage results reveal 100 percent decision and block coverage, as illustrated in Table 6-5, but both tests missed the critical errors in the IsValidMod10Number function. Table 6-5: Truth Table for Decision Testing of IsValidMod10Number Function Open table as spreadsheet Test Number Parameter number Conditional Clauses Result A1 1 2 4291 1 A2 A3 A4 Expected Actual True False /// <summary> /// Private assertion title message. /// </summary> private const String AssertionMsg = "ASSERTION FAILURE!\r\n" ; /// <summary> /// Private hard coded carriage return line feed string. /// </summary> private const String CrLf = "\r\n" ; /// <summary> /// The private assertion string boarder. /// </summary> private const String Border = "----------------------------------------\r\n" ; /// <summary> /// Output the assertion or trace message. /// </summary> /// <remarks> /// Takes care of all the output for the trace or assertion. /// </remarks> /// <param name="Message"> /// The message to display. /// </param> /// <param name="DetailMessage"> /// The detailed message to display. /// </param> /// <param name="Stk"> /// The value /// containing stack walk information for the assertion.

StringBuilder StrOut = new StringBuilder ( ) ; // If the StackArray is not null, it's an assertion. if ( null != Stk ) { StrOut.Append ( Border ) ; StrOut.Append ( AssertionMsg ) ; StrOut.Append ( Border ) ; } // Pop on the message. StrOut.Append ( Message ) ; StrOut.Append ( CrLf ) ; // Poke on the detail message if it's there. if ( null != DetailMessage ) { StrOut.Append ( DetailMessage ) ; StrOut.Append ( CrLf ) ; } // If an assertion, show the stack below a border. if ( null != Stk ) { StrOut.Append ( Border ) ; } // Go through and poke on all the stack information // if it's present. if ( null != Stk ) { Stk.SourceIndentString = " Stk.FunctionIndent = " } // Since I use the string multiple places, get it once here. String FinalString = StrOut.ToString ( ) ; if ( ( true == m_ShowDebugLog 89 ) && " ; " ; The IsValidMod10Number function has four conditional clauses. Using a simplified formula of counting the number of conditional clauses and adding 1, we calculate a cyclomatic complexity of 5. There are logically five basis paths; however, in this example we are able to traverse only four basis paths. This is because it is impossible for duplicate decisions within a function to have conflicting As we saw in 4, the XmlTextWriter class provides methods for encoding and writing arrays of bytes, and an image no matter the format is just an array of bytes. A further step is needed to transform the Bitmap object into an array of bytes that make up a JPEG image. To convert a Bitmap object to a real-world image format, you must use the Save method. The Save method can accept only a file name or a stream, however. To solve this problem, you first save the bitmap as a JPEG image to a memory stream. Next you read back the contents of the stream as an array of bytes and write it to an XmlTextWriter object as BinHex or base64 code, as shown here: // Save the bitmap to a memory stream MemoryStream ms = new MemoryStream(); bmp.Save(ms, ImageFormat.Jpeg); int size = (int) ms.Length; // Read back the bytes of the image byte[] img = new byte[size]; img = ms.GetBuffer(); ms.Close(); The preceding code snippet converts the instance of the Bitmap object that contains the bar chart to an array of bytes the img variable that represents the JPEG version of the bitmap. As the final step, you encode the bytes as BinHex (or base64, if you prefer) and write them to an XML stream, as shown here: // Prepare the writer StringWriter buf = new StringWriter(); XmlTextWriter xmlw = new XmlTextWriter(buf); xmlw.Formatting = Formatting.Indented; // Write the XML document xmlw.WriteStartDocument(); xmlw.WriteComment("Sales report for "+ m_Year.ToString()); xmlw.WriteStartElement("jpeg"); xmlw.WriteAttributeString("Size", size.ToString()); xmlw.WriteBinHex(img, 0, size); xmlw.WriteEndElement(); xmlw.WriteEndDocument(); // Extract the string and close the writer string tmp = buf.ToString(); xmlw.Close(); buf.Close(); StrOut.Append ( Stk.ToString ( ) ) ; vb.net itextsharp pdfreader How to Extract Text from PDF Document in C#, VB .
