• Thoughts on streamlining multiple .Net apps

  - by John Virgolino

  We have a series of ASP.Net applications that have been written over the course of 8 years. Mostly in the first 3-4 years. They have been running quite well with little maintenance, but new functionality is being requested and we are running into IDE and platform issues. The apps were written in .Net 1.x and 2.x and run in separate spaces but are presented as a single suite of applications which use a common navigation toolbar (implemented as a user control). Every time we want to add something to a menu in the nav we have to modify it in all the apps which is a pain. Also, the various versions of Crystal reports and that we used tables to organize the visual elements and we end up with a mess, especially with all the multi-platform .Net versions running. We need to streamline the suite of apps and make it easier to add on new apps without a hassle. We also need to bring all these apps under one .Net platform and IDE. In addition, there is a WordPress blog styled to match the style of the application suite "integrated" into the UI and a link to a MediaWiki Wiki application as well. My current thinking is to use an open source content management system (CMS) like Joomla (PHP based unfortunately, but it works well) as the user interface framework for style templating and menu management. Joomla's article management would allow us to migrate the Wiki content into articles which could be published without interfering with the .Net apps. Then essentially use an IFrame within an "article" to "host" the .Net application, then... Upgrade the .Net apps to VS2010, strip out all the common header/footer controls and migrate the styles to use the style sheets used in the CMS. As I write this, I certainly realize this is a lot of work and there are optimization issues which this may cause as well as using IFrames seems a bit like cheating and I've read about issues with IFrames. I know that we could use .Net application styling, but it seems like a lot more work (not sure really). Also, the use of a CMS to handle the blog and wiki also seems appealing, unless there is a .Net CMS out there that can handle all of these requirements. Given this information, I am looking to know if I am totally going in the wrong direction? We tried to use open source and integrate it over time, but not this has become hard to maintain. Am I not aware of some technology out there that will meet our requirements? Did we do this right and should we just focus on getting the .Net streamlined? I understand that no matter what we do, it's going to be a lot of work. The communities considerable experience would be helpful. Thanks!! PS - A complete rewrite is not an option.

• how to start with a voip/public announcement project?

  - by Metiu

  The main requirements are: open source solution on Linux support P2P VoIP calls support presence support multicast VoIP announcements (and maybe some way of setting up such a "conference") preferably serverless (maybe the network can get split and I'd need to keep the functionality for all clients that still see each other) I tried looking at telepathy, in particular telepathy-salut, but it seems to be quite a new technology, so it lacks clear/good documentation and/or working examples. I'm also evaluating SIP (e.g. SofiaSIP), but it's working only if connected to a server.

• MySQL More Tables or More Rows

  - by Pez Cuckow

  I am working on a game that I am going to open to the public to have on their game. The game stores lots of information (about 300 rows) per website and spends a lot of time updating values within this MySQL database. Is it better (faster/efficient) to add a new table for every website or to just have 1000's of rows in one table and add a column "website_id" or similar?

• Is there a good .Net CSS aggregator that combines style sheets and minifies them?

  - by vfilby

  I am looking to see if there is an open source/free project that provides a CSS manager. I am looking for this mainly for performance tweaking and hoping there is a readymade project rather than building from scratch. Features I am looking for include: Combines multiple .css files into a single css file Optionally minifies the resulting .css file Works well with .Net (a user control, custom handler, etc) Is there a project out that that handles this?

• Disable Source tab in Google Code

  - by Ngu Soon Hui

  How to disable source tab in Google Code? I don't want any random users to look at my code. Before you say that this can't be done, that Google Code is by default open source. Someone managed to do it, somehow. Edit: Before you downvote me further, take a look at the link I provided. It's possible to do it, despite whatever you want to say. And I want to know how.

• Any Suggestions for Opening a .asc (ASCII) file when Notepad doesn't do the trick?

  - by ajdams

  I was attempting to open a raw data file (.asc) format with Notepad and am getting gibberish like the following: 1A120090900007 01Piedmont Federal Savings Bank 16 W 3rd St 00 02 1F120090900007 CCR134 +0000000000CCR180 Now, I tried searching around as to what this formatting might be but haven't been able to find anything (thought it might be ActionScript but I doubt it). Does anyone recognize this formatting or know why it may not be opening properly?

• "preprocess current file" addin for Visual Studio? (C++ )

  - by Virgil

  I realize that Visual Studio has the "/P" option to generate preprocessed files, but it's extremely inconvenient. I'm looking for an addin that allows you to right-click on a file and select "view preprocessed" - or any similar solution that would basically preprocess the currently-open file (with the appropriate options from the current configuration) and show me the output, with no extra hassle. Does such a thing exist?

• Cannot place breakpoint in gdb in emacs

  I'm trying to debug a small program I've written in C. I open up the file in emacs, M-x gdb, give the program filename (a.out). When i switch to the source file in the emacs pane, and try to place a breakpoint in the main function, I get the message "No default breakpoint address now." and the breakpoint doesn't place, so I can't debug the program. I'm compiling the program with the options gcc -Wall -ansi -pedantic-errors -Werror. Any ideas?

• Redirecting one file to another using dub2 and strtok

  - by Sergiy Zakharov

  OK, here goes. I have to write a program, in which I need to use strtok and dup2 to redirect one file to another, but I need to also have the user to actually put the command cat < file1 file2, but not from the shell, but instead by using my program. That's why I need strtok. And the reason my program doesn't work is probably because of that, because I don't really understand how strtok works. I found a similar program on the internet, but they just take the ls command and redirect it to the file. That's it. My program is much more complicated. I mean, it would've been easier just to say in shell cat < file1 file2, but for some reason they want us to do it this way. So, anyways, here is what I have so far (here I just combined what I have found on the internet with what I already had from before. We had to do something similar but then the user would just go ls or ls -l. Very simple stuff. This is much harder, for me, at least.) #include <fcntl.h> #include <unistd.h> #include <stdio.h> #include <errno.h> #include <sys/wait.h> #include <string.h> int main() { pid_t pid; char line[256]; char *args[129]; int i; int fd; int status; char *temp; while (1) { printf(">"); if (fgets(line, 256, stdin) == 0) { exit(0); } else { pid = fork(); if (pid == 0) { i = 0; temp = strtok("<",line); while (temp != NULL) { args[i++] = temp; temp = strtok(">",line); args[i] = '\0'; } fd = open("hello", O_RDONLY); dup2(fd, STDIN_FILENO); fd = open("world", O_WRONLY|O_CREAT|O_TRUNC, S_IRWXU); dup2(fd, STDOUT_FILENO ); close(fd); execvp(args[0], args); } else { close(fd); wait(&status); } } } } Any help would be greatly appreciated.

• How can I match a match a null byte (0x00) in the Visual Studio binary editor with a find using a re

  - by Paul K

  Open a file in the Visual Studio binary editor that contains a null byte (0x00), then use the Quick Find feature (Ctrl +F) to find null bytes. I would have thought I could use a regular expression such as \x00 to match null bytes but it doesn't work. Searching for any other hex value using this method works fine. Is this a VS bug, 'feature', or am I just missing something? Is there a work around?

• Any addins for VS2010 to support VS2005 prjects?

  Hello. Some of the old projects in our company are left to be built with VS2005 in autobuild system (making them built correctly in 2010 costs time). Is it any addins for VS2010 that will allow to open VS2005 project and edit it's files without converting project file itself to VS2010 format (converting will kill autobuild)? Of course i can create a separate project named "xxx_vs2010.vcproj" for each of such products, but that will be a mess :(.

• Reopening serial port fails if not closed properly with CloseHandle

  - by superg

  I am working with USB device on Windows that is seen as a virtual serial port. I can communicate with the device using CreateFile and ReadFile functions, but in some cases my application does not call CloseHandle (when my application in development crashes). After that all calls to CreateFile fail (ERROR_ACCESS_DENIED), and the only solution is to log in to my computer again. Is there any way to force closing the open handle (or reopening) programmatically?
