View 1 Replies View RelatedI want to write my own application which would fetch some data from a web site. I need to parse the HTML code of the web site and get the data.
About the application:A form (main form) that will contain data arranged in rows. Some of the data comes from a web site and some of it comes from a database.The data that comes from the web site needs to be updated every few seconds so I need to keep fetching the data from the web site.The main form will contain a button "add" which when clicked will add a new row. New data can be added to this row by the user.
I am not sure what to use for this. I have been writing the application as a Windows Form Application (Visual C#) but I do not know whether this is the best choice. Should it be a windows form application or web application? Should I use something else?
We have a C++ 5.0 app that does something like this:
Creates the excel dispatch, exports the data, etc...
...
then calls these functions:
xlsApp.SetDisplayAlerts(TRUE);
xlsApp.SetVisible(TRUE);
xlsApp.SetUserControl(TRUE);
This has always worked to display the excel spreadsheet in the foreground, most recently on Windows Server 2003.
Now, testing on Windows Server 2008, the excel spreadsheet is created, but in the background. How to force it to the foreground?

The project is about reading data from PIC and display the data on the dialogue created by the MFC GUI of Visual studio 2010. There are 4 data need to be displayed (2 weight and 2 angle). the data will be display on the edit control box on the dialogue.
I have try to solve the COMPort and Readdata issues many times, but I'm fail. I have read many sources and implement the source codes... They are never work....
The detail about the issues that I need to solve is clearly mentioned on the main dialogue.cpp. Take a look to an uploaded zip file that I have attached.
I heard that you can't use it with express, but that doesn't seem right... Can you use it with Codeblocks, at least? I just hate the Qt Creator IDE. I don't like the UI... all I want to do is code Qt. I don't care much for the GUI editors.

How to create/use a graphical interface. Especially since Microsoft has removed Windows Form Application support from Visual Studio 2012 and 2013.
I know that Windows Form Application is still supported with C#, but C# is definitely not an option as the program I am developing is heavily depended on some of C++'s more advanced features not present in C#.
Is there an alternative to Windows Form Application? I would definitely prefer one, as I doubt that some workarounds would work for long. What are common ways to create a GUI application in C++? There certainly must be some ways. In Java one would use something like JFrame.
Crossplattformcompatibility: The program I am creating is a Microsoft Windows program only. So I don't care if it runs on Linux or Mac. It only has to run from Windows 7 onward. So if there are more than one standard ways to create a GUI, I would prefer the one working best for Windows.
By the way, I am using Visual Studio 2013.
I want to have a multi user chat over TCP/IP. I already have the code for both the server and the client and so far I am able to send messages from the client to the server. Now I want to make it a multi user chat. I am executing the codes using Visual studio's Command prompt(not Windows Command Prompt). I have read somewhere that we have to use select() function.

View 2 Replies View RelatedI stumbled upon an unexpected difference between GCC and VisualStudio: Different overloaded functions are called in the following example:
// -------- can assume this is located in 'tool.h' file --------------
// Fwd declaration support foo( const int& ) gets called as expected by both compilers
// void foo( const int& n );
template< typename T >
void foo( const T& n ) {
[Code] ....
What happens: I expected that by calling bar(1) compiler will notice both versions of foo() and call the best match, in this case foo(const int&). That is not the case.
Note that overloaded foo(const int&) is below bar(). It seems that at that point GCC does not see overloaded version, and happily calls template version. Visual studio on the other hand has no problem finding them both.
If I introduce a forward declaration of foo( const int& ) before bar(), both compilers call that version correctly. Unfortunately, that is not a solution for my problem here.
Template version is part of a library while overloaded is part of the user code. Both would be located in different (header) files and I would not like to impose #include order to the users or to be dependant on it.
So I am using Visual Studio 2012 Professional, this is C++ code. I am just trying to get the remainder from a very simple division. Nothing difficult, heres the code:
double getProbability(){
int rd = random();
int max = numeric_limits<int>::max();
double result = rd % max;
cout << "Probability: " << result << "
";
return result;
}
When I look at the values in debug I get:
max 2147483647
rd 1804289383
result 1804289383.0000000
That is completely wrong. The answer should be 0.840188. What is going on here?
random() just returns a number from a vector that was prepopulated with "random" integers. Not really random, but that isn't all that important. What is important is why on earth is a % operation returning such a huge number. I assigned the values to variables so I could look at them in the debugger. I know I am going to probably get a thousand different ways that I could do this "better" but again, that isn't what I am looking for. I would just like to know why the % operation is doing what it is doing?
I have a project that is essentially a hot pot of C/asm (naked functions etc). The code gets injected into another EXE. It works fine when compiled in Visual C++ 6 but when compiled in Visual Studio 2008 it compiles fine but falls over in use.
Are there certain settings I need to look out for? I have optimization disabled and as far as I can tell the command line options for compiler/linker are the same (given the differences).
I have opened both builds in IDA and the 2008 build has more import and offset jumps are in different places.
I downloaded Visual Studio 2013 on a new laptop. On my old one I could press things like ctrl + F7 to compile and ctrl + F5 to start without debugging however now it isn't responding when I type those commands. Nothing happens at all.
