Hi all,
I am doing an update system which gets updates of a software from a site. Now the update is in the form of a zip file. What I am using is:
ShellExecute( this->m_hWnd, "open", InstallerPath.c_str(), NULL, NULL, SW_SHOWNORMAL);
This is what I am using when it was direct to exe now the format has been changed to zip. Any advice on how I will do this. I want to be able to install the installer inside the zip file which is in .exe
Thanks,
Jayjay

Write code to
1. unzip the zip and
2. run the installer
3. Cleanup

Search CodeProject for Unzip.

So, you did not read the thread, did you?

Let me say it again: The OP is already receiving a zip file from somewhere, and his problem is to run the executable which is within that zip file. How can Winzip self-extractor help?

Winzip self-extractor was just an example. If you see the link I posted earlier, it gives usage details. He could have used his existing mechanism to launch the self-extractor instead of EXE

He is providing an update mechanism (which just executes a file using ShellExecute). The updates are coming to him from *a site*. Please read his original message. I won't be talking on this any further, as it serves no good to anybody.

I said "I believed" (past tense). I was not defending my answer but simply explaining what I believed and thought while answering.
I have deleted my previous posts. I agree, it serves no good to anybody and I'll stop here.

Try to replace LoadBitmap with LoadImage and use it with LR_CREATEDIBSECTION flag.
|
|
|
|
|
Using load image with LR_CREATEDIBSECTION is making no difference, the image is not getting displayed and i get the same blank window.

In your code I coudn't find a call to SetProp(). But you are calling HBITMAP hbmp =(HBITMAP) GetProp(hwnd,"hbmp");
So I guess in the main function after the LoadBitmap(), you must call the SetProp() also.

Hi All
Can any one give me tutorial or example link of How to Copy USB Data to System.When any one try to copy Data from usb Device to System(PC) then show a message.
Plz help me
|
|

You can't copy data from USB to system. USB is very different than the serial port, you can't simply access it and read what's on the bus. Instead you have to communicate to a specific device that is sitting on the bus though its driver. To open the driver, call CreateFile with the device symbolic name as argument to the function (which depends on the device to which you want to communicate). Once you got the handle to the driver, you can start excahnging information with the device through WriteFile/ReadFile. You can also exchange device specific codes through DeviceIOControl but these codes are also dependant on the device. So, it really depends on the type of device you would like to communicate with. Which device is it ?
If it is a kind of development board, you should have received some documentation with it that describes how to communicate with it.

|
|
you have any documentation or link then plz give me
|
|
|
|
|
No, I don't because you didn't answer my question. And furthermore, this totally depends on the device with which you want to communicate.
|
|
|
|
|
Ok Device type is pendrive,ipode..
|
|
|
|
|
For the pendrive, you can access it the same way you access a local file, the driver takes care of that. I don't know for the ipod but I guess it is a similar principle. Anyway, you will never really see that these devices are accessed through USB.

ok Now can you give me tutorial link
