.NET Development Refrerenced memory at 0x0000000c could not be "read"?
Hello all you nice people out there in 'Sanity' land, First - a message from my sponsor: 'For the record, I'm no computer wiz. And, I also do not know all-a-da proper terminologies either. This is stated before someone ups and decides to send any defamatory e-mail my way. Thank you.' You may now return to your regularly non-scheduled e-mails. Ah, hello again. Now, sledge-in-hand, let's have it. I had installed the VisualBasic Express, oh, about 2wks ago. A very short time thereafter I got an error message. It read, reads, as follows: aspnet_state.exe. Application Error. The instruction at 0x6a2a2fec referenced memory at 0x0000000c could not be "read". ...Show All

Game Technologies: DirectX, XNA, XACT, etc. Joypad problems
Hi have just set up C# EE and XNA game studio, no problems there.

Windows Forms Is it possible to set a user control to be owner drawn?
I have this user control that is acting like a form. It contains buttons inside of it, and you move it around a window. But I don't want to use a form because I add this control to a panel that is my background for my main window. Basically I want complete control for drawing this user control because I'm trying to get around the whole 'transparency is set to the parent's background color' thing/hack and implement true transparency in my own draw code. Any help would be much appreciated. Eh, I tried a bunch of things. At one point I was creating a bitmap, so I could do per pixel alpha, then trying to use "DrawFromBitmap" but that function was causing weird issues like making programs outside of m ...Show All
Visual Studio Express Editions Application.StartupPath in DLL
I often use Application.StartupPath in my applications. Now I want to use something similiar from within a dll but I can't find any code to do it. All I get is "Application" is undefined. I want to get the StartupPath of the application that calls the dll. Is it possible A code snippet would help. Roger The Application class is defined within the System.Windows.Forms.dll assembly and if you add a reference to it you will have access to it. Don't forget to add a 'using System.Windows.Forms' to the top of the file you are using Application.StartupPath in so that you do not have to type it's full name (unless you want to ). ...Show All
Visual C++ is this the correct/best way to set file size?
Hello everyone, I have verified that the following approach works to set the size of a file (newly created file) to be 100 bytes, but I am not sure whether it is the correct/best way to have a maximum portability (I need to write code on both Windows and Linux). Could anyone give me any comments [CODE] #include <fcntl.h> #include <sys/types.h> #include <sys/stat.h> #include <io.h> #include <stdio.h> int main() { FILE* file = fopen ("foo123", "w+"); fseek (file, 99, SEEK_SET); fprintf (file, "x"); fclose (file); return 0; } [/CODE] thanks in advance, George Thank you Sam, Sam Hobbs wrote: UNIX and Linux are ...Show All
SQL Server Indexing Question
I am somewhat new to SQL and have an indexing question I have a table that consists of 60 columns of mostly numeric data. Included in the table are fields called Customerid, CustDate and CustTime. Every hour data is posted to the table with the current time and date as well as customerID. The table is about 6 million rows. I have a query that reads: SELECT CustomerID, custdate + custtime as date FROM Mytable WHERE CustID = 905 and (date between ‘1/1/7’ and ‘1/17/7). The query works but it takes longer than I would like so I am wondering if it’s an indexing issue. Currently my table is indexed as CustomerID + CustDate + CustTime. None of the fields are unique, but the combination of the 3 i ...Show All

Software Development for Windows Vista Changes to WMI on Vista that would prevent custom WMI Provider DLL from loading?
I have a WMI Provider DLL that I devloped a couple of years ago that is used to gather some extra system info and put it in the CIMV2 namespace. It has worked fine on 2000 and XP, but when I try and use it on Vista it doesn't appear to even be loading. MOFCOMP on my MOF file runs OK, as well as regsvr32 with the DLL. I can see the class in the WMI Browser, but no istances of my WMI object. The DLL is based on the C++ framework code generated by the "Microsoft WMI Code Generation Engine" from the WMI SDK released a few years ago. I have tried turning off UAC in Vista but that doesn't seem to make any difference. I haven't been able to find any specific info about why the WMI Provider DLL woudn't work on Vista. Are there any specif ...Show All
