    Process Status Analysis – the first steps

    I am pleased to announce my first cross-platform and open source project, the Process Status Analysis tool, available on GitHub. The Process Status Analysis (psa) is a command line tool that offer some Operating System processes analysis features: – Get all processes loaded in memory information – Get process only used memory – Print processes tree – Top most “expensive” processes – Redirect output to a file

  • Flexible changes for product version properties – Visual C++ binaries

    Manually editing of binaries version in the resource editor of Visual Studio IDE is not a viable solution. If we have dozens of projects in our solution, then for each kit building we should need manual resources file edit. Otherwise, we can use a special tool that does this thing for us. Unfortunately this approach is not the most flexible and could fail. For our flexible binaries properties changes and in order to avoid manual edit for each rebuild we can create and include a header file (version.h) that contains some constants of product version and file version of our project (.rc files). We have to include only these constants into this file (version.h): #define PRODUCT_VERSION 4.3.2.198 #define PRODUCT_VERSION_STR “4.3.2.198” Then, for each .rc file wherever we have FileVersion and ProductVersion we have to use this constants. When we will build a new kit, we have to change only these constants and then to start the kit building process. Everything is fine until we add new controls in our projects resource files. Then, because of Visual Studio IDE automation we can get an unlikely surprise: the FileVersion and the ProductVersion properties could be reset to 1.0.0.0. In order to avoid this issue and edit the version only in a single place I propose the following workaround.

  • File size fast detection

    Many times in our job, we need to work with files and need to know file properties. One of the most important properties is file size. Of course, there are a lot of API that allows finding this property, but most of them needs additional file operations: open file, find file size and close file. continue…

  • Dynamic popup and drop down menus for custom representations

    Many applications allow dynamic customization for visual objects or data views. For instance, well known Internet Explorer application provides toolbars customization using a popup menu that appears when the user execute right click mouse action in toolbar zone area. Internet Explorer sample menu Other sample where this kind of menu is very useful is when it’s used in order to customize database data representation in Windows controls like List control or grid control. These kind of applications allow data filtering and show/hide columns using this kind of menu. The user just right click on control header and gets what he need. []
