hi i would to create a tools to make life easy. i would like to join a few basic setup file on fresh installed pc's. but i only wanna do a few click and not look @ the screen @ the each of each individual setup file. i would program the order how to execute, open the setup file from known feeware /media software / ccleaner / etc, and programaticly click the button of the setup file. there use to be a very known free anti spam / add program from the netherlands with did this. it's easy to check the open processes for names. but what to do next, if you have the handle of the setup file windows? how do i make the very wel known 'next' button go click? i have pretty wide knowlegde of visual c#, i have done some Nokia Qt c++, made a custom control draw control in like 2 days or so. but not to much ms vc++, accept some mfc years ago. the idea is, the app has to run on 1 minute old fresh windows installation. so i would like to try it in c++. how to scan all the processes running by 'username' in proceslist? to get handle of the window, to find handle of the wanted button, checkboxes? another posibility is to make the mouse move and click, since you know the the setup windows location. set Focus, you probably can send a winproc message to the operation system and make it click. read updates from progres bars, panel change. could anyone help me solf this problem, ith any usefull info. thank you

wel the program is for my customers. the computers i sell and install, debug & fix for my clients in my friends lilte store. so i have 'admin' acces from first moment on. yes, i wanna intercept any program a user executes and attempts to write to the registry. but much investigation has to be done. because some proceses execute as 'system' and not as user. but in the first place, i only want to protect certains spots in the registry, you know the dangerous spots, run, runonce, etc, etc. the 'hook' is targetted @ people that have no clue and just chat, navigate a litle.

hmmmm, this is 'API hooking revealed[^]' instresting material. it provide something i need. hook all proceses. atleast the test app's log told me exactly what programm i have open. : )

wel, i don't know at all , but i wanna write sometol, to inform my customers that there is something wrong. i probably need to hook in the kernel or so. i read some of the links from msdn and codeproject, but stil nothing what i need, but good info. : )

yes, that's what i wanna do, hook a dll into 'windows' or explorer.exe. just like sopme virusses, accept i wanna prevent them.

this is the entire code to create a listview with a checkbox in the left upper corner of the ListView. NM_CUSTOMDRAW seams to be the message when the mouse hover over the headers. but i fail to keep the checkBox visible / ontop @ all time. if you slightly hoover of the first header, the headers mousehover effect draws over the check. anyone an idea how to prevent this?

there aint much too c++. the synthax is pretty simular, but you have to take care of cleaning recources used yourself. in c# you have the garbage handler, in c++ you don't. in c++ you would have to make a dispose methode pretty much everywhere and it looks very very simular too c# that's what makes c# the competitor of java. cheap develpment software. cheap ... because it needs less time and less acuracy to create something. you don't have to take care of freeing up recources that aren't used anymore, so you never really know if you software is actually 100%, because you don't need to think about it. if it wasn't for the 3rd party dll i use to connect to a virtual world. i wouldn't be using c# at all. translating this 3rd party dll into c++, would take me a year or so. but the downfall of DOTNET is ... you can easy reverse engineer your aplication and resell or hack it. with a simple click in a tool from the internet, you pretty much get the entire code. if you read about dotnet, you would have read the each executable actually transports the entire source and recompiles on the user machie. this is done by the JIT compiler. dotnet wil never be the tool by excellence for software venders. dotnet is used by people that didn't like the looks or feel of java, but also aren't competent or too lazy for c++. i don't live from coding, but this is what i learned in the last years. if my current project is done, i'm going Nokia Qt. power @ finger tips

i would like to achieve a checkbox on a ColumnHeader in a listview. i have been trying for days. i have achieved a checkbox on the right spot in the listview by virtual placing it on top. [DllImport("user32")] private static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent); protected override void OnHandleCreated(EventArgs e) { SetParent(_cCehckBox.Handle, Handle); base.OnHandleCreated(e); } but the visual style/effect of the header causes the checkbox to fall in the background if you hover the mouse of the header. the Header class doesn't provide anu usefull stuff, atleast i don't see any usefull stuff. i have bene reading alot about it and viewed many things regarding headers. i have also been using ... protected override void WndProc(ref Message message) { .... } filtering on WM_NOTIFY for 'HDN_ITEMCHANGINGA', 'HDN_ITEMCHANGEDA', 'HDN_BEGINTRACKA', 'HDN_BEGINTRACKW'. i used a piece of code from a project here on codeproject, virtually unchanged. but i only get the windows handle, the other things are empty.

why don't just use c++. you can included a c++ dll. but you also could download Nokia Qt C++. http://qt.nokia.com[^] download the creator + sdk bundle. there are many working opengl examples + code included. very very impressive examples. c++ is a faster than c# and THE choice for directX and OPENGL. there is also the TAO dll for c#, but it looks abandoned. c# is mainly for cheap office develpment, go c++ if you want speed. Nokia Qt rocks even better for office develpment, every control is opensource, it's easier to hook special needs. Qt includes a TimeLine class for special effects. Qt wil rule in the future. check for Kinetic scrolling tutorial. google earth is made with Qt and many other, like Adobe use Qt

i have made this piece of code, to a checkbox on the header: wel not realy on the headr, but situated there. (class ColumnHeader doesn't provide much, like for example: OnpaintEvent. but i need some help with the special effects. if you hoover the mouse over the header, the mousehover effect of the header hides the checkbox, bringing it to the background. i would like to have the checkbox ontop @ all time. using windows 7.

i'm trying to create 2 custom controls, once you compile, you have a nice custom control up in the visualstudio I.D.E.. i would like to achieve, the once a dragged 'MenuStrip' onto my form and start adding item, that these items are also a new created costrum control 'cToolStripMenuItem', instead of standart item using System; using System.Collections.Generic; using System.Windows.Forms; using System.Text; namespace OwnerDraw_Test_3 { class CMenuStrip : MenuStrip { } class cToolStripMenuItem : ToolStripMenuItem { } } kind regards

hi, i'm trying to code a Adobe Cs4 lookalike menustrip. i found some material on microsoft's MSDN. i stripted this example to a proper visual studio 2008 project. if i apply the ... this.MenuStrip1.Renderer = new RolloverItemRenderer(); it does remove the border when you hover the the mouse over a parent menuItem and simply gives a blue background and white chars. i would like to override the hoover color + border and shape of the button. also this methode is hard to use, it would be cool if you can edit the custom draw menu from the designer and the need of event. so i think it need a totaloverhaul somehow. i have experience on other control, like tabcontrol, button, etc, etc. but it seems, this needs a diffferent aproach. any volunteers to code a cool costum menu? i can mail the project. http://msdn.microsoft.com/en-us/library/system.windows.forms.toolstripitem.aspx[^]
