Hi.
My solution (working in VS 2008) has a C# console app, and a C# web service. The service has an entity data model. It has numerous stored procedures. For one of the stored procs, which just returns data (SELECT blah blah FROM...), I added a function import called "Iservice." I saved all, then in my console app, updated the service reference to my C# service. Now, in my console app, I am trying to do the following:

Hello,
I have a bunch of Image Buttons in my code. When I leave them as they are, I can build my project without problems. However, when I add OnClick to an image button, I get the error:
Too many characters in character literal
For example, the following builds with no problems:
...Code:<asp:imagebutton id="myImgBtn" style="Z-INDEX: 102; LEFT: 82px; POSITION: absolute; TOP: 8px"

C#, windows service, can't write to file
Hi.
I have a windows service that I wrote in C#. After I successfully compile it, I install it using InstallUtil, then run it with the net start command. I am trying to either log some stuff to a file, or to the Event Viewer in windows. Nothing has worked for me so far.
I am looking for help.
This is the relevant code:

I have a problem with HttpRequest.Que ryString.
There is an XML string that contains something like the following: <age>8+</age>
As you probably guessed, the "+" is the problem :)
I want to get that XML string from QueryString, however, the "+" appears as a " " (space), not a "+".
I have tried the following:

struct containing array of pointers to struct (C dll to C#)
Hi.
In C dll, there is a struct that contains an array of struct pointers. I do not know how to represent that in C#. That's my problem.
Here is the relevant C code:
[PHP]struct vector
{
uint elem_count;
uint size;
int (*cmp)(const void *, const void *);
void *table;
};
typedef struct vector VECTOR;
#define CTABLE VECTOR

C struct in dll -- > equivalent C# struct to send to dll?
Hi. I've managed to get the C code I need into a dll, and my C# program can access some functions. There are other functions though, and I don't know how to access them from C# because they involve a struct declared in the C code. The example I have been working from is the following:
C-struct:
[PHP]struct STRUCT_DLL
{
int count_int;
int* ints;
};[/PHP]
C# code:

Wow, thank you. That was dumb of me.
Well, I don't know what format is a COM dll. I could have included DllImports wherever I needed to use the certain function from the dll, but I thought it would look "cleaner" if I just put all the imports in one file. That and I wanted to try it. At any rate, I guess this is solved (thank you), and now I'm going to see what happens when I have to send in and return... -
Ok I guess starting with the example I did, and the one you linked me to, I can't create a wrapper class.
This is my code:

I just found out about MinGW and have been using that. I can make dll files from C code. However, when I use them in my C# code, compile, and then run the executable, it hangs. I've followed a bunch of tutorials (most recently, this one: http://www.adp-gmbh.ch/win/misc/mingw/dll.html ), but they all give the same result - C# executable hangs. If I use the dlls in C code, the C executable runs fine.
What am I missing here?Leave a comment:

making a .dll file with gcc to use in C# (MSVS)
Hi.
How do I use gcc to compile C code into a .dll file that can be used by my C# project?
The problem I am faced with is this: I have C code compiled with gcc. I tried making a new C++ project in visual studio (so that I can create a dll) and just copying the C code, but language extensions and void pointers prevented me from compiling. I tried compiling as C code and turning off Microsoft Language Extensions in my project... -
Disabling Microsoft Language Extensions worked (got rid of the error I described), but there are some other errors. I am assuming they are appearing for similar reasons.
Trying to compile with -pedantic with gcc resulted in warnings given (warning: pointer of type `void *' used in arithmetic) on the same lines, but not errors.
Thank you both for your help! Even though I still can't compile, at least I learned something,...Leave a comment:

Thank you for the replies.
Here is where table is defined:
If you can't do pointer arthimetic because void is of indeterminate...Code:struct vector { UINT elem_count; /* number of items in the vector */ UINT size; /* size of the vector */ UINT elem_size; /* element size */ int (*cmp)(const void *, const void *); void *table; };Leave a comment:

porting C code (unix) to a C++ prject (MSVS)
Hi.
I have a project (multiple header and source files) that was written in C, in unix. I made a new C++ project in MSVS 2005 (blank project), and am trying to simply copy the C code to my new C++ project. I thought the main problem I'd face would be finding the equivalent libraries for windows, however, I ran into another issue.
I get the following error:
error C2036: 'void *' : unknown size

Thank you.
Looks like I've found the problem.Leave a comment:

C# debugging help
Hi. I apologize in advance if this is in the wrong forum.
I am totally new to debugging my code, and the tools available. Previously, all I did was manually trace my code. However, doing that with my current problem would take way too long.
I have an object (obj A) with an attribute. I check the value of the attribute, before I add the object "into" another object (obj B). The value is correct (expected). Then... -
C# application using C code?
Hello.
I have an application, that I designed in C#.
I need to be able to use some libraries that were made in basic C. Dll files are not an option. So, without putting any C code into dlls, can my C# app access the C code? Or is my only option copying the C code, and changing it to C#?
Thanks for any help or guidance. -
