In general, what needs to be done to convert a 16 bit Windows program to Win32? I'm sure I'm not the only person to inherit a codebase and be stunned to find 16-bit code lurking in the corners. The code in question is C. ...
Hi all, I was reading up about NTVDM.exe as I build a quick test console app and it crashed on a friends machine complaining about this EXE. As I understand it all DOS cmd windows (C# console apps included) run as 16bit not 32bit. Is this true? Does this mean all my works console app back office apps are running as 16bit rather than ...
I want to see the type of a variabe whether it is unsigned 32 bit,signed 16 bit etc. How to view... ...
Hi all, I have some scientific image data that's coming out of a detector device in a 16 bit range which then gets rendered in an image. In order to display this data, I'm using OpenGL, because it should support ushorts as part of the library. I've managed to get this data into textures rendering on an OpenGL 1.4 platform, a limitatio...
Which tool/approach would you suggest to convert of a large 16bit Windows GUI application, written in old Borland Pascal 7 / OWL, to Delphi? Understanding the pretty heavy differences between OWL and VCL, as well as the differences between the pointer manipulations in 16bit pascal and the state-of-art using of strings and objects in De...
We have thousands of DOS programs that were all written in the 80s using 16-bit C, comprising over 1,000,000 lines of code. Many of these programs utilize libraries that directly access the screen, drive, etc. (and we don't have the sources for these libraries). Whenever we try to run them in Win2000 or above, even in compatibility mod...
We have a body of legacy Apps written in Borland Pascal 7.0 of 16bit, real mode Fame. Do you know any good tools useful for analyzing such software, such as call graphs, cross-references, IDEs? ...
Hi - I'm looking for a light-weight database engine for Delphi 1 (don't ask, it's a long story). Delphi 1 is 16-bit. The engine should compile into the EXE. SQL would be nice, but not mandatory. Any info would be great. Thanks, Carl ...
I like a lot of what I've read about D. Unified Documentation (That would make my job a lot easier.) Testing capability built in to the language. Debug code support in the language. Forward Declarations. (I always thought it was stupid to declare the same function twice.) Built in features to replace the Preprocessor. Modules Typedef ...
I'm trying to alter my interrupt table to take over the keyboard interrupt. My end goal is to write my new interrupt routine, copy myself into RAM and make the real-mode interrupt table point to me. I have found random sample code online but it is missing explanations on how to get the address of the original interrupt. They simply ha...
I am going through some example assembly code for 16bit real mode. I've come across the lines: mov bx, cs mov ds, bx mov si, OFFSET value1 pop es mov di, OFFSET value2 what is this doing? What does having 'OFFSET' there do? Sorry if its a very basic question, i'm new at this. ...
We are using Quest Geo Solution's Grid InQuest DLL (GIQ60.DLL) within an SQL Server Integration Services (SSIS) package. We have managed to use this without problems locally (32bit) by using tlbimp to create a .NET wrapper (interop). However, when this moved to our integration server this does not work as the server is 64bit. The GIQ6...
How can I check if two System.Drawing.Color structures represent the same color in 16 bit color depth (or generally based on the value of Screen.PrimaryScreen.BitsPerPixel)? Let's say I set Form.TransparencyKey to Value1 (of Color type), I want to check that when the user selects a new background color for the form (Value2), I don't set...
Before, when I was using win32, I used FreeImage in order to load and save bitmaps of bit depth greater than 8 bits. That's every image I work with, since I'm doing medical imaging, and before anyone says anything, yes, me and my customers have spent a lot of money on high-brightness, high-contrast monitors with 11 or 12 bits of dynamic...
I'm trying to create pdf documents on the fly in an application, i.e. a user clicks a link and a pdf document is displayed to them with some text and some images. I'm currently using FPDF v1.6 (http://www.fpdf.org/) which supports 24bit (true colour) png's but the problem I have is that this is a legacy application and there's 1000's of...
I'm having an issue using bilinear interpolation for 16 bit data. I have two images, origImage and displayImage. I want to use AffineTransformOp to filter origImage through an AffineTransform into displayImage which is the size of the display area. origImage is of type BufferedImage.TYPE_USHORT_GRAY and has a raster of type sun.awt.im...
It seems that the following is a common method given in many tutorials on switching a processor from 16-bit to 32-bit: mov eax, cr0 ; set bit 0 in CR0-go to pmode or eax, 1 mov cr0, eax Why wouldn't I simply do the following: or cr0, 1 Is there something I'm missing? Possibly the only th...
Title says it all. The error NASM gives (dispite my working OS) is "invalid effective address". Now i've seen many examples of how to use LEA and i think i gots it right but yet my NASM dislikes it. I tried "lea cx, [cx+9]" and it worked; "lea cx, [bx+cx]" didn't. Now if i extended my registers to 32-bits (i.e. "lea ecx, [ecx*8+ecx]") ...
Hi. I am building a 16 bit operating system. But character array does not seem to work. Here is my example kernel code: asm(".code16gcc\n"); void putchar(char); int main() { char *str = "hello"; putchar('A'); if(str[0]== 'h') putchar('h'); return 0; } void putchar(char val) { asm("movb %0, %%al\n" "movb $0x0E, %%a...
Hello,I'm studying ASM 8086 theoretically on highschool. And when I do this: MOV BX,[SI] is SI+1 going to BH or BL? Thank you :-) ...
