Hi,

• Added some lazy codes

Should be fixed. Added the auto-type-calc option for LCF-AT requested. Calc button has been removed. Once I'm done or get exhausted from this, I'll add the SRC. ;)

Update: Found why it's crashing. Again, same issue. I would somehow need to mix between using Decimal and BigInteger to make the input value longer, which I'm not sure I can do at this point. Appreciate the testing feedback...

OK thanks for new versions guy's. @Stuttered, looks good that you removed the calc button and to calc the results on fly but its not working if I change the format 1000 / 1024. That's bad. Maybe you can fix that too.

I have another request / question about 1000 decimal and 1024 binary. Is there a quick way to get results to see of values I enter of 1000 dec & 1024 binary?

Example: I enter 1 GB / 1024 and I get this...

...its showing all results of 1024 what sizes they have. If I change now the format to 1000 decimal I get this...

• 1,000,000,000 Byte of decimal results / copy

• Paste value into edit control

• Change format to 1024

• Change unit to Bytes and I get this results out

Maybe you guy's could add something for this too to get the results right away. Or you show all results at once. One more time about the DOT & Comma thing. You see the results of 0.93132257 GB but the DOT is a problem. If I enter this value via copy / paste into a calculator its showing "93.132.257" instead what means the calculator did not handle the DOT as Comma. Maybe you can correct that too anyhow to set the Comma where it belongs too. So I hope my requests are not too demanding. 🙂 Thanks.

Hmmm... Not sure I can do that, but I'll take a look. Here is v0.0.7.

FileSizeCALC_x86_v0.0.7.rar

not a bug just curiuos -

why TB, PB lines are always showing e+-xxx scientific format?

also would be nice to allow resizing the window as for big values one need to use scroller.....

wow!

why is that? :)

nice to have - actual build -

Only because this is how the online app does it, I guess?

this — Postimages

App still needs some clean up, and the stretchable is fine. The internal VER I don't care about atm.

@jackyjask , Can you increase the MaxLength to like 35 and see if you run into issues?

I've seen you are trying to load icon from the file on disk, but the icon is already embedded into the exe itself.... lets solve this micro puzzle:

• how to reuse existing embedded icon (as native PE resorce) and assign it into the Form icon property?

I triedd this but for some reason I hit 0 (null?) response

		[DllImport("user32.dll", SetLastError = true)]
		static extern IntPtr LoadImage(IntPtr hInstance, IntPtr lpName, uint uType, int cxDesired, int cyDesired, uint fuLoad);

		[DllImport("kernel32.dll", SetLastError = true)]
		static extern IntPtr GetModuleHandle(string lpModuleName);

		[DllImport("kernel32.dll")]
		static extern uint GetLastError();

		public Form1(string filePath = null)
		{
			const uint IMAGE_ICON = 1;
			const uint LR_DEFAULTSIZE = 0x0040;
			const uint LR_SHARED = 0x8000;

			IntPtr hm = GetModuleHandle(null);

			IntPtr hIcon = LoadImage(hm, (IntPtr)3, IMAGE_ICON, 32, 32, LR_DEFAULTSIZE | LR_SHARED);   //  0  ... why?

			uint why = GetLastError();      //  0 here  - means no issue?? WTF?!

Yeah, I saw that. There is a way to do it, but I need to go back and look at an older code project to remember how...

oooooooooops

C# .net BigInter type DOES NOT support numbers with decimal points......... what a pity!

so seems we do not have in-built .net type for very big numbers together with decimal points...

decided to use this public/free lib:

A C# implementation of arbitrary-precision numbers and arithmetic - peteroupc/Numbers

using it seems all is looking nice!

Well, I guess that's why it would not work. The icon issue is fixed, You have to add the .ico as a resource and then add code.

Right-click on project->properties. Add icon (icon and manifest).

Add .ico to .resx file (double-click and then add)

Add code below:

Code:

// Explicitly set the form's icon from the executable

try

{

this.Icon = Icon.ExtractAssociatedIcon(Application.ExecutablePath);

}

catch (Exception ex)

{

MessageBox.Show($"Error loading icon: {ex.Message}", "Icon Load Error");

}

Update:

I have incorporated the library, and may have this working... app update in a bit...

Seems like we have a winner! 👍

Hey guys,

do you know how to manage & calculate this manually via code (M)ASM? Do you have some tiny example and could test (don't debug the tools now)? So I have size as ASCII string like 64.2 MB. Are there some quick handy functions to use stings like that with? I just did remember crt_strtol & crt_atoi but they don't work with comma or dot signs etc.

Example: SizeText, What-In MB, What-Out MB, format to calc with

invoke function_A, chr$("64.2"), MB, MB, 1024 == 61.2 MB Sting output
invoke function_A, chr$("64.2"), MB, MB, 1000 == 67.3 MB String output
or
invoke function_A, chr$("64.2"), MB, GB, 1024 == 0.059 GB String output

I don't remember whether there is already some function or not so do you know?

greetz

I would suggest the FPU Library from Raymond: https://masm32.com/masmcode/rayfil/fpu.html

The FpuAtoFL function is probably what you want to convert the ascii string to a REAL4

LOCAL rSize:REAL4
Invoke FpuAtoFL, Addr szFloatString, Addr rSize, DEST_MEM4
; rSize now contains the float such as 64.2

you can then load this into the fpu (or keep it on fpu stack with DEST_FPU flag), load some conversion value into the FPU to multiply by and do the multiplication, then convert the result back to ascii with the FpuFLtoA function

Edited Thursday at 11:32 AM1 day by fearless

Hello @fearless,

thanks for the info but I need some ready example code even for the part after I got that float value etc.

String to value then calc to MB or GB or etc to string. I also don't remember those float calculation stuff and div & mul operations. Just wanna do pretty same as the conversion tool can do by using a size string and getting result as string back I want as in examples before. Some size calculation lib would be nice.

.data?
rSize		REAL4 ?

lea edi,   rSize
invoke FpuAtoFL, chr$("64.2"), edi, DEST_MEM4

rSize
004AFADC 409CCCCD <-- and then?
004AFAE0 00000000

greetz

I got something like this...

invoke FpuAtoFL, chr$("64.2"), NULL, DEST_FPU
invoke FpuAtoFL, chr$("1000"), NULL, DEST_FPU
fmul

...just to put 2 value strings into FPU register doing some multiplication and having the result in st0. The question now is how to get the value in st0 to string. As I said, I just forgot all those stuff pretty much but must be very simple somehow. I tried this other function FpuFLtoA but always get ERROR back. Seems I'm using this wrong.

Basic Questions:

• ASCII string to Float register / copy

• Float register X to ASCII string buffer

• Is there a way to limit the value with X values after comma like 64.2 or 64.23 or 64.234 + doing some round up?

I've chosen to go with decimal and binary units, rather than an additional number. E.g. "64.2 MB Mi" converts decimal to binary and "64.2 Mi MB" converts binary to decimal. If the unit isn't recognised it will be ignored (it's detected, though, so just add your own test). The output is three significant digits for numbers under 1000, no decimals otherwise.
