    <p>To start off with, I'm pretty new to C++.</p> <p>I am wanting to accomplish the following:</p> <ul> <li>Execute the following: "SampleApp.exe -cf test.xml"</li> <li>I need the shell that execute in hidden mode</li> <li>I need the C++ application to wait until SampleApp is finished</li> <li>If the SampleApp takes longer than X amount of time, then I need to terminate the process</li> <li>I want to pipe SampleApp's output to a file (sample.log)</li> </ul> <p>So far I have the following:</p> <pre><code>SHELLEXECUTEINFO lpExecInfo; lpExecInfo.cbSize = sizeof(SHELLEXECUTEINFO); lpExecInfo.lpFile = L"SampleApp.exe"; lpExecInfo.fMask = SEE_MASK_DOENVSUBST|SEE_MASK_NOCLOSEPROCESS; lpExecInfo.hwnd = NULL; lpExecInfo.lpVerb = L"open"; lpExecInfo.lpParameters = L"-cf test.xml"; lpExecInfo.lpDirectory = NULL; lpExecInfo.nShow = SW_HIDE; // hide shell during execution lpExecInfo.hInstApp = (HINSTANCE) SE_ERR_DDEFAIL; ShellExecuteEx(&amp;lpExecInfo); // wait until the process is finished if (lpExecInfo.hProcess != NULL) { ::WaitForSingleObject(lpExecInfo.hProcess, INFINITE); ::CloseHandle(lpExecInfo.hProcess); } </code></pre> <p>The above code achieves everything except piping output to a file. However, I doesn't seem to be possible with ShellExecute. It seems that I need to use CreateProcess instead. I am hoping that someone with more C++ experience would be able to provide me with the CreateProcess equivalent of my code plus piping output. If not, at least confirm that what I am wanting to do is possible and point me in the right direction.</p> <p>- Thanks</p>

    1. COThere a multiple examples on the Internet (including this site), that shows how to use `CreateProcess` to create child-processes where the parent captures the output from the child.

    2. COYes, I know but it seems that CreateProcess is quite a bit more complex than ShellExecute and the examples that I have found have varying degrees of complexity as well. I was hoping to get some advice on where to look based on my needs or even some good example code that accomplishes what I need or some of what I need.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
