<hr><a name="5"><b>Product: CodeSnitch</b></a><h4>I get the error Unable to Create Online Manager component.</h4>This occurs if you disconnect CodeSnitch from your target device, but it does not close down cleanly. You must reset your target device, or manually terminate the toolbox.exe process on the target device.

<hr><a name="33"><b>Product: CodeSnitch</b></a><h4>Why does CodeSnitch report leaks in a release build of an MFC application?</h4>CodeSnitch doesn抰 know the difference between debug and retail builds. All it does is trap calls to an API. If it doesn抰 trap a call you believe your application is making, it means either the call actually is not being made or that the module that makes the call was not instrumented by CodeSnitch.<br>
<br>
In MFC, calls to allocate objects such as brushes, fonts, and DCs are in inlined function calls, so are built directly into your application executable. However, calls to delete objects are built into the MFC DLL, either in the destructor of certain objects or during a garbage collection phase.<br>
<br>
CodeSnitch is able to instrument the debug version of MFC DLLs. When you run a debug build of your MFC application, then, CodeSnitch traps both the call to allocate objects (inlined directly in your application) and the call to free objects (in the MFC debug DLL).<br>
<br>
However, for retail builds, the MFC DLL is typically built into the ROM image of your target device. CodeSnitch is unable to instrument modules in ROM. When you run a release build of your application under CodeSnitch, only calls to allocate objects (again, inlined directly in your application) are trapped. The call to delete an object is not trapped. In this case, CodeSnitch tracks the allocations, but misses the deletes, and thus reports leaks.<br>
<br>
One way to workaround this is to make a copy of the MFC retail DLL in RAM. Many Windows CE platforms, including Pocket PC and Windows Mobile, allow RAM shadowing of modules in ROM. Once you have a RAM copy, CodeSnitch is able to instrument it and thus trap the calls to delete objects.<br>
<br>
You will find a copy of the release build of MFC included in your Windows CE SDK. For example, if you use Pocket PC 2003, typically the file will be located in "C:\Program Files\Windows CE Tools\wce420\Pocket PC 2003\MFC\Lib\ARMV4" (or X86 for emulation).<br>
<br>
Note that if you use the Remote File Viewer to make a RAM copy of the file, Remote File Viewer will complain that the destination file is read-only and cannot be written over. You must rename the file on your hard drive and then copy it to \Windows on the target device. Once it is in \Windows, Remote File Viewer will allow you to rename it with the same name as the ROM copy of the module.<br>

<hr><a name="7"><b>Product: CodeSnitch</b></a><h4>How do I track API calls in a device driver or other DLL?</h4><ol>
<li>In the Run Program dialog, enter the path of the DLL in the application path.
<li>Check the 'Instrument Only' option, as well as any desired tracking options and hit Go!.
<li>Leaving CodeSnitch connected, manually start your application that uses the DLL. When the DLL gets loaded, a new Event View window will pop up begin receiving events.
</ol>

<hr><a name="8"><b>Product: CodeSnitch</b></a><h4>Can I run my application in the debugger and track it in CodeSnitch at the same time?</h4>Yes.<br>
<br>
<ol>
<li>Build and Download your application like you normally would from eMbedded Visual C++.
<li>Enter the application path in the Run Program Dialog.
<li>Check the desired tracking options.
<li>Check the 'Instrument Only' option, then hit Go!.
<li>In EVC, start the debugger. EVT will check the file, then report that it is up to date. Events should start appearing in a new window in CodeSnitch once the application loads.
</ol>
Note: In order for this to work, you must not rebuild the application after you hit Go! in CodeSnitch, or EVT will download the new version over the instrumented version!<br>

<hr><a name="9"><b>Product: CodeSnitch</b></a><h4>CodeSnitch reports an address and DLL name instead of function and line number</h4>CodeSnitch was unable to find symbolic information for a module, or no symbols<br>
existed for the specified address.<br>
<br>
Make sure you have debug symbols turned on in the project settings for your application or module. If you generated your application with the wizard, Debug configurations have symbols by default, but Release configurations do not.<br>
<br>
To generate symbols:<br>
<br>
<ol>
<li>In your EVC workspace, click the "Project\Settings..." menu command.
