  • Can't Add XSD to Class Project

    - by Jeff
    Background: I started with a large solution with many applications in it in VS 2008 and I'm trying to split it up. Steps to repeat: I create a new VS 2010 C# class project I right click and choose add existing item I choose the XSD file from my old project and import it. The original file is 67KB the imported file is 18KB Line 134,135 of the original file <Mapping SourceColumn="ConfigType" DataSetColumn="ConfigType" /> <Mapping SourceColumn="ConfigValue" DataSetColumn="ConfigValue" /> Line 135,136 of the resulting file <Mapping SourceColumn="ConfigType" DataSetColumn="ConfigType" /> <Mappi Part way through it's life my old project was upgrade from 2.0 to 3.5 so some of the code is. Manually copy and paste of the xsd source into the new file and updating the 2.0.0.0 to 4.0.0.0 allowed me to open it it in The GUI for editing XSD files. After fixing all the connection strings and right clicking on every query and clicking configure then finish I was able to gain access to one of the tableadapters out of 6. I'm stumped as to hoe to get this to compile. Once it compiles I'm open sourcing it so ask if you want to see the code.

  • VS2010 + IE8 Debugging woes - Element not found

    - by Chin
    I am having great difficulty trying to debug with vs2010 and IE8, though I think the problem is more IE8 specific. When starting a debug session 9 times out of 10 I will have the following problem. IE tab says connecting.. - then after a 5 second wait I will get an error in VS saying element not found. Even when I click ok to dismiss the error, the IE window still shows connecting... I will then have to kill the IE process to be able to close IE to try again. Sometimes however I am lucky and it starts. But the whole thing is so random I have no clue where to start. One thing I have noticed is that I always have 2 IE processes started even though there is only one window open. One has a small footprint of 100k, I presume it is some kind of helper. I am using a static port with the built in WebDev server. If anyone has had similar problems please let me know how you resolved it. Its driving me nuts! thanks

  • Linking Error Building 64bit Qt app on 32bit XP machine.

    - by photo_tom
    I'm trying to build a 64 bit version of my application (and yes I really do need the memory) on my 32bit xp dev box for production testing on our Vista64 server. Previously, I have built w/o any errors the Qt 4.6.2 DLL's in 64 bit mode. That step went vary smooth. Just to get started in building production, I'm trying to rebuild Qt's Star Delegate demo in 64bit mode. I converted the 32bit to 64bit app by changing the application configuration and adjusting the library's to the 64bit venisons. Now, when I go to link, I'm getting the following error when I link 1>------ Build started: Project: stardelegate, Configuration: Release x64 ------ 1>Linking... 1>MSVCRT.lib(crtexew.obj) : error LNK2001: unresolved external symbol WinMain 1>release64\stardelegate.exe : fatal error LNK1120: 1 unresolved externals Suggestions? edit - After some more searching, discovered if I link as a console app it will work and run. But not as a windows app. And I don't have this problem in 32 bit mode.

  • Programatically building an MSI

    - by pm_2
    I would like to create a C# program that creates an MSI based on a number of parameters. For example, based on user settings, certain files would be included, or runtime parameters set. Can anyone point me towards any documentation that might help, or give me an idea where I might start with something like this?

  • How do you specify a 64 bit unsigned int const 0x8000000000000000 in VS2008?

    - by Mark Franjione
    I read about the Microsoft specific suffix "i64" for integer constants. I want to do an UNsigned shift to a ULONGLONG. ULONGLONG bigNum64 = 0x800000000000000i64 >> myval; In normal C, I would use the suffix "U", e.g. the similar 32 bit operation would be ULONG bigNum32 = 0x80000000U >> myval; I do NOT want the 2's complement sign extension to propogate through the high bits. I want an UNSIGNED shift on a 64 bit const number. I think my first statement is going to do a SIGNED shift right. I tried 0x800000000000000i64U and 0x800000000000000u64 but got compiler errors.

  • Getting information about where c++ exceptions are thrown inside of catch block?

    - by tfinniga
    I've got a c++ app that wraps large parts of code in try blocks. When I catch exceptions I can return the user to a stable state, which is nice. But I'm not longer receiving crash dumps. I'd really like to figure out where in the code the exception is taking place, so I can log it and fix it. Being able to get a dump without halting the application would be ideal, but I'm not sure that's possible. Is there some way I can figure out where the exception was thrown from within the catch block? If it's useful, I'm using native msvc++ on windows xp and higher. My plan is to simply log the crashes to a file on the various users' machines, and then upload the crashlogs once they get to a certain size.

    Hi Guys, I am writing a tool which can be used to make the matrix for the current performance of the project. For that I required to get the time taken by each file to get compiled. I tried with the following option but didn't succeed :( Tools-Options-Proejcts & Solutions - VC++ Project Settings - Build Timing- Yes From the above option I am able to get the whole time taken to build the solution but my problem is to get for each one. I am using VS2005 So anyone is having any idea then pls revert back ASAP....

  • When debugging in VS 2008 why does the debugger land on a second return statement?

    - by Hellfire
    When debugging the following console program: class Program { static void Main(string[] args) { Console.WriteLine(DoIt(false)); Console.WriteLine(DoIt(true)); } private static Boolean DoIt(Boolean abort) { try { throw new InvalidOperationException(); } catch(Exception ex) { if (abort) { return true; } Console.WriteLine("Got here"); return false; } } } Why does the IDE land on the second return statement during the second call to DoIt()? The results of the execution is correct but the debugging experience is misleading. Is this a known issue? Is the behavior in VS 2010 the same?

  • vcxproj file won't load into solution.

    - by John C
    We've just recently switched to VS 2010 and i had a solution that was working fine. This moring when i try to load the solution i get the error: "An item with the same key has already been added." This occurs when it is trying to load one of our main projects and it is not loaded. I assumed the problem was with my solution so i created a brand new empty solution and tried to load the same vcxproj and got exactly the same error. When i revert the project file to a previous version it works, so apparently it's something in the vcxproj file. However it also appears that i'm the only one in the office that is affected. So some combination of the vcxproj file and my computer seems to be the issue. Has anyone seen anything like this before? Any ideas on a solution? Thanks

  • Will a VS2008 setup project update Net 3.5 SP1?

    - by rathkopf
    I just started using the WPF WebBrowser that is included in Net 3.5 SP1. I built my setup project (which I have been using prior to moving to 3.5 SP1) and installed it on a test machine but the WebBrowser was not available. What must I do to be sure that the setup.exe/msi combination checks for and installs SP1?

  • The right way to setup VisualStudio 2010 for OpenCL

    - by LonliLokli
    what is the right way to setup VisualStuio 2010 for working with *.cl files? I have added *.cl under Tool/Text editor/File extensions and copied usertype.dat into the common7/ide folder, but VS underlines keywords like float4 or cross. Is it necessary to add some key in registry or can somebody propose a tutorial? Thanks in advance. PS i have already asked similar question old one question, but now i am looking explicit for a solution with vs2010. It is not bad, but really nerves and deflects me from programming tasks.

  • How can I create an array of random numbers in C++

    - by Nick
    Instead of The ELEMENTS being 25 is there a way to randomly generate a large array of elements....10000, 100000, or even 1000000 elements and then use my insertion sort algorithms. I am trying to have a large array of elements and use insertion sort to put them in order and then also in reverse order. Next I used clock() in the time.h file to figure out the run time of each algorithm. I am trying to test with a large amount of numbers. #define ELEMENTS 25 void insertion_sort(int x[],int length); void insertion_sort_reverse(int x[],int length); int main() { clock_t tStart = clock(); int B[ELEMENTS]={4,2,5,6,1,3,17,14,67,45,32,66,88, 78,69,92,93,21,25,23,71,61,59,60,30}; int x; cout<<"Not Sorted: "<<endl; for(x=0;x<ELEMENTS;x++) cout<<B[x]<<endl; insertion_sort(B,ELEMENTS); cout <<"Sorted Normal: "<<endl; for(x=0;x<ELEMENTS;x++) cout<< B[x] <<endl; insertion_sort_reverse(B,ELEMENTS); cout <<"Sorted Reverse: "<<endl; for(x=0;x<ELEMENTS;x++) cout<< B[x] <<endl; double seconds = clock() / double(CLK_TCK); cout << "This program has been running for " << seconds << " seconds." << endl; system("pause"); return 0; }

  • VS2010: New and improved Intellisense?

    - by George
    In VB.NET type this on a new line: DateAdd( Shouldn't a dropdown picklist of enum values appear? It used to! I miss it! Of course, this is just one example where an enum pick list does not appear where it did before. Can anyone defend this or is it a bug?

  • Why Resource (.resx) file added on merely changing Form size and on adding button which is not resou

    - by Muhammad Kashif Nadeem
    1- Resource files suppose to be added on adding some resource in application like image or audio or video etc. But if I just change size of form a .resx file under that particular form. Changing size of form does not add any resource so why this .resx file. 2- I dropped a button on form and a resource file is included again this button is not some kind of resource, it is object created and having information in designer file. 3- A resource file added on dropping button on form but if I delete this resource file and run application it compile and run with NO error and button is still there. If this button has any relation with resource file then there must by some kind of compile or runtime error AND if .resx file has nothing to do with button then why it was added? I am using VS 2008. Thanks in advance for the help

  • Strange output produced by program

    - by Boom_mooB
    I think that my code works. However, it outputs 01111E5, or 17B879DD, or something like that. Can someone please tell me why. I am aware that I set the limit of P instead of 10,001. My code is like that because I start with 3, skipping the prime number 2. #include <iostream> bool prime (int i) { bool result = true; int isitprime = i; for(int j = 2; j < isitprime; j++) ///prime number tester { if(isitprime%j == 0) result = false; } return result; } int main (void) { using namespace std; int PrimeNumbers = 1; int x = 0; for (int i = 3 ; PrimeNumbers <=10000; i++) { if(prime(i)) { int prime = i; PrimeNumbers +=1; } } cout<<prime<<endl; system ("pause"); return 0; }
