How to make the custom icon tranparent in MFC?

I have a small problem: I built an MFC application using MSVC 14.0 it works fine but somehow I wanted to change the default Icon so I added another icon to "res" folder and Named it as the main icon.



Now after build I get the new icon on my Dialog and in taskbar but it show the background! (white color) I need the background to be Transparent as the IDE does with my default MFC Icon.



After searching I had been suggested to use Image Editor on MSVC but I can't find that toolbar there! I only get the colors when opening the icon to edit in MSVC.



So how could I make the Icon background transparent? I used to use WINAPI where to use BitBlt but I don't know how here in MFC. Thank you.




  • I also see that Toolbar Editor is grayed in Image menu.

    In "Resource View", double click on the icon. Or, in "Solution Explorer" find "myapp.rc", double click it, and double click the icon. When you see the icon editor, go to main menu, click "Image -> Show color window" It shouldn't be gray unless the icon is read-only, or another program is editing the icon.

    I don't know what the problem is. Just create a new icon and draw on it. Post a screen shot of this gray toolbar.

    The icon/image editor in Visual Studio doesn't really support alpha transparency (32bpp), instead it does support 24bpp images, and you can set some portions of the image to be (fully) transparent, or inverse transparent. If this is OK to you fine, otherwise use an external editor. 32bpp images and icons can be included in your resources and compiled without problem; it's just the VS image editor that can't edit them.

count number of partitions of a set with n elements into k subsets

up vote 6 down vote favorite 1 This program is for count number of partitions of a set with n elements into k subsets I am confusing here return k*countP(n-1, k) + countP(n-1, k-1); can some one explain what is happening here? why we are multiplying with k? NOTE->I know this is not the best way to calculate number of partitions that would be DP // A C++ program to count number of partitions // of a set with n elements into k subsets #include<iostream> using namespace std; // Returns count of different partitions of n // elements in k subsets int countP(int n, int k) { // Base cases if (n == 0 || k == 0 || k > n) return 0; if (k == 1 || k == n) return 1; // S(n+1, k) = k*S(n, k) + S(n, k-1) return k*countP(n-1, k) + countP(n-1, k-1); } // Driver program int ma

A CLEAN and SIMPLE way to add appendices to Table of Contents and bookmarks

Image
0 I found a lot of questions abount appendices and ToC. Many users want appendices to be grouped in an Appendix part, however some problems arise with ToC, hyperref, PDF viewer bookmarks, and so on. There are different solutions which require extra packages, command patching and other extra code, however none of them satisfies me. I almost found an easy way to accomplish a good result, where appendices are added to bookmarks in the right way and hyperref links point to the right page. However, the number of the "Appendix" part page is wrong (it's the number of appendix A). Is there any EASY way to fix that? This is a MWE: documentclass{book} usepackage[nottoc,notlot,notlof]{tocbibind} usepackage{hyperref} begin{document} frontmatter tableofcontents mainmatter part{First} chapter{
