• .NET Development ERR - WebClient.DownloadData returns "protocol violation"

  I'm getting a "protocol violation" from a site that is working perfectly fine when I issue WebClient.DownloadData as such: WebClient WebClient_Temp = new WebClient(); byte[] zbyteTemp = WebClient_Temp.DownloadData ( "http://MySite/MyWebPage.htm" ); I have heard of the app.config file fix, but my app is a UserControl, and as such, I can not keep the "MyApp.dll.config" in the same directory as such: <configuration> <system.net> <settings> <httpWebRequest useUnsafeHeaderParsing = "true" /> </settings> </system.net> </configuration> I've also tried putting a <link> element into m ...Show All

• Visual C# How to determine file reading progress

  I am using streamreader to read lines of text from a file. I would like to indicate on a progress bar the status of the reading process. What would be the best way to determine where I am within the file so that I could divide this number by the filename.Length member to display in my statusBar I'm having trouble finding the right method for indicating where the file pointer is... You can try checking yourStreamReader.BaseStream.Position. I guess it could be a bit off though due to buffering done by the StreamReader.     ...Show All

• .NET Development VS 2005 OLEDB Update Parameter question.

  We have just upgraded from Visual Studio 2003 to 2005. In VS 2003, I had been working on some web pages that had datagrids populated from an Oracle database and had figured out how to update and insert records. I am now relearning everything for VS 2005. I have been able to get a grid populated, sorted, and updated. All of this with just the "visual" side of the IDE (no hand written code.) The current problem is updating a CHAR(25) field. If I replace a letter or space with something, it updates. But if I click at the end of the current text and add characters without deleting a corresponding number of padding spaces I ...Show All

• Visual C++ VC2005 %50 Slower then VC2003

  I just migrated a graphics application from VC2003 to VC2005.  After building it, I ran a small benchmark & found that VC2005 code was about %50 slower. The Application does a great deal of floating point and integer calculations.  It also converts doubles to int quite a bit (the VC2003 version used SSE to handle this). The VC2003 version used /G7 and /Ow (which are not available in VC2005) Compiler Switches Used: (vc2003)/arch:SSE2 /c /EHa /FD /GF /GL /Gs8192 /Gy /MT /nologo /O2 /Ob2 /Og /Oi /Ot /Ow /Oy /TP /W3 /WX /Zi (vc2005)/arch:SSE2 /c /EHa /FD /G7 /GF /GL /GS- /Gs8192 /Gy /MT /nologo /O2 /Ob2 /Og /Oi /Ot /Oy /TP ...Show All

• Windows Forms Loading application efficiently

  Is there a better way to improve startup performance of my application I had a form wherein it had 2 comboboxes and 2 datagridviews, each and everyone bounded to their respective tables in my databse.The tables happens to be of large data so evidently it takes so much time before my applications starts up.I am using the tableadapter.fill method of loading data on form load event and its such a big drawback on my part.Thanks in advance. I have no idea why loading a dataGridView could take much time. How much time is it, and do you have special columns (images, ...). Maybe someone else has more experien ...Show All

  Is there way to enable the rules only for the derived classes and not for the base class. I tried public override TargetVisibilities TargetVisibility { get { return TargetVisibilities .ExternallyVisible; } } is there any other approch thanks in advance RamV Hi RamV, Are you looking for classes that derive a specific base class or are you looking for all the 'leaf' classes (the classes that derive from other classes but nobody derives from them) If you're looking for the first, you can just check if their BaseClass property is set to the base class you're looking ...Show All

• Visual FoxPro Source is out of date

  This is what I see when I open the debugger' Trace window . Right before I begin any execution but after the form with all the controls and all associated prg files is brought up. I want to know what source it is talking about. Is it source code In which sense is it out of date Is it my source code or FoxPro's in some way I may believe that I perhaps use some operators that have been deprecated but there is no indication where to look. I do not use the trace option. As the worst case scenario I would use breakpoints so I do not have much observation as to how it changes if at all during debugging but it seems the message stays put. ...Show All
