• Which format does static library (*.lib) files use? Where can I find "Official" specifications of *.

  - by claws

  Just now I found that static libraries in *nix systems, in other words *.a libraries are nothing but archives of relocatables(*.o files) in ar fromat. What about static libraries(*.lib files) in windows? Which format are they in? I found an article: http://www.microsoft.com/msj/0498/hood0498.aspx which explains *.lib file structure. But Where can I find "Official" specifications of *.lib file structure/format? Other than ar.exe of mingw is there any tool from Microsoft which extracts relocatable objects of *.lib & *.a files? EDIT: I wonder why I'm unable to get to this question. If there are no official specifications. Then how does the compiler ('linker' to be more correct) writers work with *.LIB files?

  - by Aaron

  Question: What is the difference between: vector<string> and vector<char *>? How would I pass a value of data type: string to a function, that specifically accepts: const char *? For instance: vector<string> args(argv, argv + argc); vector<string>::iterator i; void foo (const char *); //*i I understand using vector<char *>: I'll have to copy the data, as well as the pointer Edit: Thanks for input!

• MS Detours Library, detouring non win api function

  - by flavour404

  Hi, I want to use the windows detours library to detour a non win api function. The function is part of the Qt library (QtGui4.dll). I am wondering how I would set up the function signature for : void QPainter::drawText ( const QPointF & position, const QString & text ) I had a go with this and it received my usual share of errors, a little explanation of requirements would be interesting as well: void (QPainter * real_drawText)(const QPointF & position, const QString & text) = drawText This is what they look like for TextOut, under the windows API: BOOL (WINAPI * Real_TextOut)(HDC a0, int a1, int a2, LPCWSTR a3, int a4) = TextOutW; BOOL WINAPI Mine_TextOut(HDC hdc,int X,int Y,LPCWSTR text,int textLen) { BOOL rv = Real_TextOut(hdc, X, Y, text, textLen); HWND hWindow = WindowFromDC(hdc); SendTextMessage(hWindow, text); return rv; } Thanks.

• onTextChanged Event for many Textboxes c#

  - by Alan Bennett

  Hi, I am currently building a prototype for a new system screen, and i am using c# to build this. The question i have is, i currently have 14 textboxes which are filled from a condition from a couple of other controls on the screen. these 14 textboxes all add up to a total shown in another textbox. as these textboxes are editable (in case the client wishes to increase the value) (cant go into to much detail but they will) I need to have a firable ontextchange event for when the values change so the total box updates. however i have a feeling there must be a way of not having to create 14 different events, is there a way that i can have 1 event which fires if any of the 14 text boxes are fired? thanks Alan

• Using excel import wizard through code?

  - by baron

  I am creating a Generate Report button for some data in my application. The report will just generate a CSV file, which I then automatically launch in excel. Problem is with one of the data fields, is text and has leading zeroes (which I need to keep). When the file is automatically opened in excel, excel automatically trims these. Is there anyway I can get it so that it opens with the data in the format I want it. I know you achieve this normally by opening the CSV file from within excel and can do the import wizard. So one potential solution would be to auto open the import wizard when the app launches this file. I don't know if this is possible. Thanks for reading.

• C89, Mixing Variable Declarations and Code

  - by rutski

  I'm very curious to know why exactly C89 compilers will dump on you when you try to mix variable declarations and code, like this for example: rutski@imac:~$ cat test.c #include <stdio.h> int main(void) { printf("Hello World!\n"); int x = 7; printf("%d!\n", x); return 0; } rutski@imac:~$ gcc -std=c89 -pedantic test.c test.c: In function ‘main’: test.c:7: warning: ISO C90 forbids mixed declarations and code rutski@imac:~$ Yes, you can avoid this sort of thing by staying away from -pedantic. But then your code is no longer standards compliant. And as anybody capable of answering this post probably already knows, this is not just a theoretical concern. Platforms like Microsoft's C compiler enforce this quick in the standard under any and all circumstances. Given how ancient C is, I would imagine that this feature is due to some historical issue dating back to the extraordinary hardware limitations of the 70's, but I don't know the details. Or am I totally wrong there?

• Ant - using vssadd to add multiple file

  - by mamendex

  Hi, I'm trying to use vssadd task to add a tree of source files to a recent created project on VSS. But it happens to be adding only the folder tree, all files missing. <vsscp vsspath="$/DEV/APL_${version}" ssdir="${vssapl}" serverPath="${vsssvr}"/> The vssadd task displays the name of the folders it's creating: ... (vssadd) $/DEV/APL_0.0.10c/src/domain: (vssadd) $/DEV/APL_0.0.10c/src/mbeans: (vssadd) $/DEV/APL_0.0.10c/src/service: ... The script runs successfully but the files never get in the repository. Trying to use wilcards are no good, the task says it found no matching files and ss returns with a code of 100: <vssadd ssdir="${vssapl}" localPath="C:\Workspace\APL_Build*.*" recursive="true" serverPath="${vsssvr}" comment="Build ${versao} at ${to.timestamp}"/ I've noticed that vssadd does not accept fileset tag either, so I'm kind of lost here. Any tips? tks

  I have a complex inheritance structure in my data model. A majority of classes in my model (which is designed in VS 2010 with a DB generated by it after) are derived from 3 basic classes. And only these 3 classes can be found among the context members. How do I use all the derived classes at all?

• Do I have to remove VS 2010 beta1 in order to get a web app to work on asp.net 2.0?

  - by Galilyou

  I think the title is enough :). I have VS 2010 beta1 installed, and I wish to run an asp.net mvc application on my local IIS. The problem is, the asp.net 4.0 runtime is selected by default for all the web sites, when I try to change it to asp.net 2.0, I get the following error message: I click yes, then ok, and when I get back to the ASP.NET tab of my site's properties, I see the 4.0 version is selected back again! Do I have to remove VS 2010 in order to get this to work? (hopefully not) Ps: I'm using windows XP and IIS 5.1

• How to query a CGI based webserver from an app written in MFC (MSVC 2008) and process the result?

  - by shan23

  Hi, I am exploring the option of querying a web-page, which has a CGI script running on its end, with a search string (say in the form of http://sw.mycompany.com/~tools/cgi-bin/script.cgi?param1=value1&param2=value2&param3=value3 ), and displaying the result on my app (after due processing of course). My app is written in MFC C++ , and I must confess that I have never attempted anything related to network programming before. Is what I'm trying to do very infeasible ? If not, could anyone point me at the resources I need to look at in order to go about this ? Thanks !

• How can I debug this web service http handler?

  - by baron

  Hello everyone, I am building a Httphandler following these instructions here It manipulates HTTP POST and HTTP GET. I have a client with two buttons two POST and GET. After i've tested and happy everythings working I move it from localhost to IIS. Now when I do this I get an exception in the POST handler code. How on earth can I debug this code line by line? I managed to do this awhile ago, I thought it was by attaching to process but I can't work it out. I can emulate GET just by typing address in browser, post im not sure about. I've tried telnetting and sending it from there but haven't had any luck.

• Is there a Firebug console -vsdoc.js?

  - by David Murdoch

  If not, does anyone care to write one? I would do it myself...but I don't have time right now...maybe next week (unless someone beats me to it). If you are bored and want to compile the vsdoc: Here is the Firebug API. Here is a blog post about the format for VS doc comments for intellisense. Here is an example vsdoc (jquery-1.4.1-vsdoc.js). I created the following because I kept typing cosnole instead of console. You can use it as a starting point (ish). console = { /// <summary> /// 1: The javascript console /// </summary> /// <returns type="Object" /> }; console.log = function (object) { /// <summary> /// Write to the console's log /// </summary> /// <returns type="null" /> /// <param name="object" type="Object"> /// Write the object to the console's log /// </param> };

• MFC CDialog not showing

  - by Jesus_21

  here is my problem : In my Solution, I have 2 projects, one is a lib in which I created a ressource file (mylib.rc) and a dialog template in it. Then I made a class which inherits CDialog and uses this template. But when I instantiate it and call DoModal(), nothing appends... here the code of my class, is something wrong with it ? MyDialog.h /*MyDialog.h*/ #pragma once #include "../../../resource.h" class MyDialog : public CDialog { enum {IDD=IDD_DLGTEMPLATE}; public: MyDialog(CWnd* pParent = NULL); virtual ~MyDialog(); protected: virtual BOOL OnInitDialog(); DECLARE_MESSAGE_MAP() private: afx_msg void OnBnClickedOk(); afx_msg void OnBnClickedCancel(); }; MyDialog.cpp /*MyDialog.cpp*/ #include "stdafx.h" #include "MyDialog.h" MyDialog::MyDialog(CWnd* pParent /*=NULL*/) : CDialog(IDD_DLGTEMPLATE, pParent) {} MyDialog::~MyDialog() {} BOOL MyDialog::OnInitDialog() { return TRUE; } BEGIN_MESSAGE_MAP(MyDialog, CDialog) ON_BN_CLICKED(IDOK, &MyDialog::OnBnClickedOk) ON_BN_CLICKED(IDCANCEL, &MyDialog::OnBnClickedCancel) END_MESSAGE_MAP() void MyDialog::OnBnClickedOk() { OnOK(); } void MyDialog::OnBnClickedCancel() { OnCancel(); }

• Active Directory Membership Provider - how to expand on this?

  - by Jaxidian

  I'm working on getting an MVC app up and running via AD Membership Provider and I'm having some issues figuring this out. I have a base configuration setup and working when I login as [email protected] + password. <connectionStrings> <add name="MyConnString" connectionString="LDAP://domaincontroller/OU=Product Users,DC=my,DC=domain,DC=com" /> </connectionStrings> <membership defaultProvider="MyProvider"> <providers> <clear /> <add name="MyProvider" connectionStringName="MyConnString" connectionUsername="my.domain.com\service_account" connectionPassword="biguglypassword" type="System.Web.Security.ActiveDirectoryMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" /> </providers> </membership> However, I'd LIKE to do some other things and I'm not sure how to go about them. Login without typing the domain (i.e. the "@my.domain.com"). I realize that this could only work if I limit myself to just one domain - that's fine. Organize users in up to N different OUs within a single OU. As you can tell from my current connection string, I'm authenticating users in my Product Users OU. I would LIKE to create OUs for various companies within this OU and put the users into those OUs. How can I authenticate across all of these different OUs? I'm trying to figure out how the Active Directory Membership Provider ties in with the Profile and Role providers. Are there AD versions of those too or am I stuck with SQL, home-grown, or finding something somebody else has coded up? Many thanks!!

• NUnit for VS has suddenly bombed.. Anyone else experience this?

  - by Ian P

  I'm getting the following set of errors in a project, that previously worked fine, from NUnit for VS when I try to run either individual or all of the tests in a given solution. Error loading C:\Path to Application\Application\Application.ApplicationTests\bin\Debug\Application.ApplicationTests.dll: The method or operation is not implemented. Error loading C:\Path to Application\Application\Application.FileDetectorTests\bin\Debug\FileDetectorTests.dll: The method or operation is not implemented. Error loading C:\Path to Application\Application\Application.PresentationTests\bin\Debug\Application.PresentationTests.dll: The method or operation is not implemented. Error loading C:\Path to Application\Application\Application.DomainTests\bin\Debug\Application.DomainTests.dll: The method or operation is not implemented. I've verified that each project is setup with the appropriate ProjectTypeGuids for a test project in the Project file. I've tried uninstalling / reinstalling NUnit for VS, but have had no luck. Does anyone have any advice as to how I might start troubleshooting this? If I open each individual test project outside of the main solution (that includes all projects, by the way,) and save it as it's own solution, they run just fine. Nothing of note has changed since this stopped working. Thanks! Ian

• Implementing sub fields in a PropertyGrid

  - by evolve

  Alright so my terminology when it comes to C# isn't great, so I'll attempt to explain this with a small example. If you create a class which you are using within a PropertyGrid and you have the following values: class Test { public Point example { get; set; } } This will produce a PropertyGrid which has an expandable object "example" which has fields X and Y in order to create a "Point". I'm attempting to create an object "name" which has fields "firstname" and "lastname", so I have: class Test { public Name example { get; set; } } public struct Name { public string firstname { get; set; } public string lastname { get; set; } } This however isn't working as intended. I think I need to override some method(s) in order to get this working, however since I don't really have the terminology down for PropertyGrids it is difficult for me to find a solution. Any help would be great.
