hey

so i am using LoadImageW()

to open an image and use it

but i want to embed the image inside the program

so that the file doesnt have to be present the pwd

win32 api

windows c++ in mingw env

one idea that i have is that embed the bitmap in its raw format into a char array

and then use this

to like open a bitmap from a buffer

https://stackoverflow.com/questions/2886831/win32-c-c-load-image-from-memory-buffer

please answer

hi

Can somebody tell me how to get the type name of a variable in C? (Not C++)

I tried typeof, typeid... But they are undefined, and if I try to include <typeinfo>, I can't...

I was researching the same from this eve. Couldn't find any workable solution so far

I tried typeof, typeid... But they are undefined, and if I try to include <typeinfo>, I can't...

typeid and <typeinfo> are in C++

From discord: You can't get types at runtime in C. C doesn't use runtime typing, everything's just raw bytes.

Any workaround to differentiate int and char would be helpful! As I am writing a wrapper functions for db select query. Without identifing type I have to use if/switch for every column.! Any help welcome !

Why do you need a variable name? You know it yourself, just write it in quotation marks

but i want to embed the image inside the program

pls help

Hi, I need help marshalling a C struct into C#, I need to keep the 3rd dimension array called (byte[,,,]) dates. c struct __attribute__((__packed__)) mcmap_region_header //8KiB file header { struct mcmap_region_chunk_location locations[32][32]; //chunk (x,z)'s location atom is at locations[z][x] when x & z are positive; location[31-z][31-x] when negative uint8_t dates[32][32][4]; //UNIX timestamps for when each chunk was last modified }; I use [MarshalAs(UnmanagedType.ByValArray, SizeConst = 32 * 32 * 4)] attr, without luck, I researched on Google, and I saw LPArray value from UnmanagedType enum, but there isn't any parameter to specify the dimensions: cs public struct McmapRegionHeader //8KiB file header { //public McmapRegionChunkLocation[,] Locations = new McmapRegionChunkLocation[32, 32]; //chunk (x,z)'s location atom is at locations[z][x] when x & z are positive; location[31-z][31-x] when negative //public byte[,,] Dates = new byte[32, 32, 4]; //UNIX timestamps for when each chunk was last modified [MarshalAs(UnmanagedType.ByValArray, SizeConst = 32 * 32)] public McmapRegionChunkLocation[,] Locations; //chunk (x,z)'s location atom is at locations[z][x] when x & z are positive; location[31-z][31-x] when negative [MarshalAs(UnmanagedType.ByValArray, SizeConst = 32 * 32 * 4)] public byte[,,] Dates; //UNIX timestamps for when each chunk was last modified }

Greetings, does anybody knows where can I found info about VHDL?

Can somebody tell me how to get the type name of a variable in C? (Not C++)

This is impossible (even in c++). To have variable type you must first form it during compile time and write to some other variable having correspondence with this variable, at start of the program. This can be done ,f.e., in COM for some variables. So you will need something similar. Actually if you really need this, this is an indicator that you do something very wrong.

db types won't likely match those of c. As they told you c doesn't have any mean to identify types. The only workaround I can think of is having the types in a table in the db or a config file

Where is MADGUGULA

#include <stdio.h> int menghitungCelcius(int celcius,int reamur,int fahrenheit,int kelvin); int main(){ int celcius,reamur,fahrenheit,kelvin; printf("Masukkan derajat suhu CELCIUS yang akan dikonversi: "); scanf("%d", &celcius); printf("KONFERSI suhu: \nReamur: %d \nFahrenheit: %d \nKelvin: %d\n",reamur, fahrenheit, kelvin); } int menghitungCelcius(int celcius,int reamur,int fahrenheit,int kelvin){ reamur = celcius*4/5; fahrenheit = (celcius*9/5)+32; kelvin = celcius + 273; return reamur,fahrenheit,kelvin; } i'm a newbie and i'm trying to make function but i have something wrong here,the result is always same if i start the program

You didn't call the function

hii

And returning with comma operator doesn't work the way you think it works

You have a lack of some knowledge

You have a lack of some knowledge

And you need to fulfill it

Yes. Going with metadata table to keep those. Thanks !

👍👍

You didn't call the function

i have called the function but it still doesn't work tha the result is still same

what should i do?

what should i do?

Don't do anything illegal.

You did not call

You did not call

menghitungCelcius(celcius,reamur,fahrenheit,kelvin);

i have tried but the result still doesn't change

How to delete and free up memory taken by a vector object?

How to delete and free up memory taken by a vector object?

It happens automatically

But is there a way to delete the object instance in a vector? I would get an error if I do it because of double deletion

vector::erase you need?

The problem is let's say I create a vector of class A. And if I keep appending back to the vector. I would run out of memory

I was trying to find a way to delete / free up elements in my vector which I won't need

In which langauge and do you have pointer for that memory?

Delete the pointer.

erase them

Or let old vector be deleted and use another

Or maybe you need another data structure and not vector

Structure is not a class and it's not reserved by your program automatically, you can just delete the pointer to mermory location and that is it. If you're using malloc then use free() if you're using C++ use delete or free

What you mean reserved?

And using malloc and free in C++ is not recommended

But possible

Reserved means when you call malloc the program looks for not used memory and instruct the OS that these bytes are blocked by my program.

Reserved means when you call malloc the program looks for not used memory and instruct the OS that these bytes are blocked by my program.

And whats the difference regarding classes and structs?

They are the same thing in C++

Structure if used without malloc doesn't matter because you can ignore the point and your structure is dead.

Class if object is created out of it, then that object doesn't die automatically if you're not in scope and has to be killed and resources freed.
