  • how to resolve this .Net 3.5 warning/error?

    - by 5YrsLaterDBA
    I have three machines. one installed VS2008 another two installed SDK6 and Framework3.5 (one of these two is a build machine). When I use MSBuild to build our application, all of them get this warning: C:\WINDOWS\Microsoft.NET\Framework\v3.5\Microsoft.Common.targets : warning MSB3245: Could not resolve this reference. Could not locate the assembly "WPFToolkit, Version=3.5.40128.1, Culture=neutral, PublicKeyToken=31bf3856ad364e35". Check to make sure the assembly exists on disk. If this reference is required by your code, you may get compilation errors. and the build machine comes with some errors: scsm\SCSM.cs(234,13): error CS1501: No overload for method 'Invoke' takes '1' arguments scsm\SCSM.cs(235,13): error CS1501: No overload for method 'Invoke' takes '1' arguments scsm\SCSM.cs(304,13): error CS1501: No overload for method 'Invoke' takes '1' arguments scsm\SCSM.cs(314,13): error CS1501: No overload for method 'Invoke' takes '1' arguments scsm\SCSM.cs(317,13): error CS1501: No overload for method 'Invoke' takes '1' arguments scsm\SCSM.cs(323,17): error CS1501: No overload for method 'Invoke' takes '1' arguments scsm\SCSM.cs(324,17): error CS1501: No overload for method 'Invoke' takes '1' arguments scsm\SCSM.cs(325,17): error CS1501: No overload for method 'Invoke' takes '1' arguments but other machines are passed without error. Resources are identical in those three machines. searched online but cannot find answer. Anybody here can help me resolve this? thanks

  • What does this mean: warning: converting from ‘void (ClassName::*)()’ to ‘void (*)()’

    - by Brendan Long
    I have a member function in a class that has a callback, but the callback isn't strictly neccessary, so it has a default callback, which is empty. It seems to work fine, but I get an annoying warning: warning: converting from ‘void (ClassName::*)()’ to ‘void (*)()’ I'm trying to figure out what it means and how to turn it off (or fix it if I really am doing something wrong). Here's some simple code: class ClassName{ public: void doSomething(void (*callbackFunction)() = (void(*)()) &ClassName::doNothing){ callbackFunction(); } void doNothing(){} }; int main(){ ClassName x; x.doSomething(); return 0; } Note: If I do this (without explicitly casting it as a void(*)()): void doSomething(void (*callbackFunction)() = &ClassName::doNothing) I get this: main.cpp:3: error: default argument for parameter of type ‘void (*)()’ has type ‘void (ClassName::*)()’

  • Delphi - E2010 Incompatible types: 'Integer' and 'Char' - Any ideas

    - by zeencat
    I've been tasked with porting a legacy Delphi application over to C# .Net. The original delphi developer left several months before I was hired. I'm receiving the E2010 Incompatible types: 'Integer' and 'Char' error for the below method. I'm trying to compile the application within the Delphi 2007 IDE, I've been told that original application is either Delphi 4 or 5 if that helps any. I understand what the error is telling me but I don't understand why\how it is applied to the code snippet below. Any help\direction would be greatly appreciated. Thanks in advance function StrIComp_JOH_PAS_1(const Str1, Str2: PChar): Integer; var Ch1, Ch2 : Char; Offset : Integer; PStr : PChar; begin; PStr := Str1; Offset := Str2 - PStr; repeat Ch1 := Upper[PStr^]; Ch2 := Upper[PStr[Offset]]; if (Ch1 = #0) or (Ch1 <> Ch2) then Break; Inc(PStr); until False; Result := Integer(Ch1) - Integer(Ch2); end;

  • Determining the maximum stack depth

    - by Joa Ebert
    Imagine I have a stack-based toy language that comes with the operations Push, Pop, Jump and If. I have a program and its input is the toy language. For instance I get the sequence Push 1 Push 1 Pop Pop In that case the maximum stack would be 2. A more complicated example would use branches. Push 1 Push true If .success Pop Jump .continue .success: Push 1 Push 1 Pop Pop Pop .continue: In this case the maximum stack would be 3. However it is not possible to get the maximum stack by walking top to bottom as shown in this case since it would result in a stack-underflow error actually. CFGs to the rescue you can build a graph and walk every possible path of the basic blocks you have. However since the number of paths can grow quickly for n vertices you get (n-1)! possible paths. My current approach is to simplify the graph as much as possible and to have less possible paths. This works but I would consider it ugly. Is there a better (read: faster) way to attack this problem? I am fine if the algorithm produces a stack depth that is not optimal. If the correct stack size is m then my only constraint is that the result n is n = m. Is there maybe a greedy algorithm available that would produce a good result here?

  • Question about Objective C calling convention and argument passing on ARM

    - by overboming
    I want to know how objective C runtime handle arguments when I call a objective C method like [NSString stringWithFomat:@"%@, %@", @"Hello", @"World"] There are three arguments for this objective C call, how does it work compared to typical way on a ARM system. I have known register r0, r1, r2, r3 will hold first 4 arguments, how about there are additional arguments? How does it put them on a stack and pop them later?

  • How does Visual Studio decide the order in which stack variables should be allocated?

    - by Jason
    I'm trying to turn some of the programs in gera's Insecure Programming by example into client/server applications that could be used in capture the flag scenarios to teach exploit development. The problem I'm having is that I'm not sure how Visual Studio (I'm using 2005 Professional Edition) decides where to allocate variables on the stack. When I compile and run example 1: int main() { int cookie; char buf[80]; printf("buf: %08x cookie: %08x\n", &buf, &cookie); gets(buf); if (cookie == 0x41424344) printf("you win!\n"); } I get the following result: buf: 0012ff14 cookie: 0012ff64 buf starts at an address eighty bytes lower than cookie, and any four bytes that are copied in buf after the first eighty will appear in cookie. The problem I'm having is when I place this code in some other function. When I compile and run the following code, I get a different result: buf appears at an address greater than cookie's. void ClientSocketHandler(SOCKET cs){ int cookie; char buf[80]; char stringToSend[160]; int numBytesRecved; int totalNumBytes; sprintf(stringToSend,"buf: %08x cookie: %08x\n",&buf,&cookie); send(cs,stringToSend,strlen(stringToSend),NULL); The result is: buf: 0012fd00 cookie: 0012fcfc Now there is no way to set cookie to arbitrary data via overwriting buf. Is there any way to tell Visual Studio to allocate cookie before buf? Is there any way to tell beforehand how the variables will be allocated? Thanks, Jason

  • Circular file references not allowed

    - by Program.X
    Hi, I am having a problem in building my solution in VS2008. Normally, it compiles fine in the environment. Sometimes, it fails with: /xxx_WEB/secure/CMSManagedTargetPage.aspx(1): error ASPPARSE: Circular file references are not allowed. I rebuild and it works fine. Now, however, I am in the middle of setting up a CruiseControl.NET system and am testing my checked out code with MSBuild before I integrate the build into CC. Now, everytime I MSBuild, I get: "Q:\cc\xxx\checked out from svn\xxx.sln" (default target) (1) -> (xxx_WEB target) -> /xxx_WEB/secure/CMSManagedTargetPage.aspx(1): error ASPPARSE: Circular file references are not allowed. Problem is, I can't see where this reference is. I have searched for the reference across the entire solution and canf ind no references to the page itself (CMSManagedTargetPage) anywhere other than in the page or its codebehind, or within a string, eg: C:\dev2008\xxx\IWW.xxx.ASPNET\AspxHttpHandler.cs(82): inputFile = context.Server.MapPath("~/secure/CMSManagedTargetPage.aspx"); C:\dev2008\xxx\IWW.xxx.ASPNET\AspxHttpHandler.cs(83): virtualPath = "~/secure/CMSManagedTargetPage.aspx"; My assembly references are also fine (as far as I know). My Web Application is at the "top" of the dependencies, and nothing references it and therefore the faulting page so cannot cause a circular reference. Of course, the page itself may reference something such as a UserControl within the same assembly/web site, but as mentioned earlier, a search on CMSManagedTargetPage yielded no results so this is not happening. Changing the batch attribute in web.config had no effect on MSBuild. I find it very odd that it "sometimes" fails in VS and always fails in MSBuild. Am I missing some subtlety?

  • How to write the Visitor Pattern for Abstract Syntax Tree in Python?

    - by bodacydo
    My collegue suggested me to write a visitor pattern to navigate the AST. Can anyone tell me more how would I start writing it? As far as I understand, each Node in AST would have visit() method (?) that would somehow get called (from where?). That about concludes my understanding. To simplify everything, suppose I have nodes Root, Expression, Number, Op and the tree looks like this: Root | Op(+) / \ / \ Number(5) \ Op(*) / \ / \ / \ Number(2) Number(444) Can anyone think of how the visitor pattern would visit this tree to produce output: 5 + 2 * 444 Thanks, Boda Cydo.

  • Can you precompile and merge part of an ASP.NET website and then continue development?

    - by michielvoo
    A big part of the web site is precompiled and merged, since it's almost never going to change. The precompiled bits can be replaced in case of updates to the original. I want to continue development of new pages, but when I browse to a new page I get the following error: The file '/Website/Test/Default.aspx' has not been pre-compiled, and cannot be requested. Is there any way around this? Edit: If I remove the precompileApp.config file I get the contents of the marker files when I browse them: This is a marker file generated by the precompilation tool, and should not be deleted!

  • How to overcome vc++ warning C4003 while writing common code for both gcc and vc++

    - by compbugs
    I have a code that is compiled in both gcc and vc++. The code has a common macro which is called in two scenarios. When we pass some parameters to it. When we don't want to pass any parameters to it. An example of such a code is: #define B(X) A1##X int main() { int B(123), B(); return 0; } The expect output from the pre-processing step of compilation is: int main() { int A1123, A1; return 0; } The output for both gcc and vc++ is as expected, but vc++ gives a warning: warning C4003: not enough actual parameters for macro 'B' How can I remove this warning and yet get the expected output? Thanks.

Even other sample grammars that come with ANTLR (such as the CMinus grammar) exhibit this behavior.

  • identation control while developing a small python like language

    - by sap
    Hello, Im developing a small python like language using flex, byacc (for lexical and parsing) and C++, but i have a few questions regarding scope control. just as python it uses white spaces (or tabs) for identation, not only that but i want to implement index breaking like for instance if you type "break 2" inside a while loop thats inside another while loop it would not only break from the last one but from the first loop as well (hence the number 2 after break) and so on. example: while 1 while 1 break 2 end end #after break 2 it would jump right here but since i dont have an "anti" tab character to check when a scope ends (like C for example i would just use the '}' char) i was wondering if this method would the the best: i would define a global variable, like "int tabIndex" on my yacc file that i would access in my lex file using extern. then everytime i find a tab character on my lex file i would increment that variable by 1. when parsing on my yacc file if i find a "break" keyword i would decrement by the amount typed after it from the tabIndex variable, and when i reach and EOF after compiling and i get a tabIndex != 0 i would output compilation error. now the problem is, whats the best way to see if the identation got reduced, should i read \b (backspace) chars from lex and then reduce the tabIndex variable (when the user doesnt use break)? another method to achieve this? also just another small question, i want every executable to have its starting point on the function called start() should i hardcode this onto my yacc file? sorry for the long question any help is greatly appretiated. also if someone can provide an yacc file for python would be nice as a guideline (tried looking on google and had no luck). thanks in advance.
