Some time ago you posted your SamplingProfiler here. I downloaded it bact then, but started to investigate it just now... looks great! But I have two problems / suggestions: Fist, I use JCL exception dialog with embbeded map file. As you may know JCL comes with "Insert JCL debug data" expert - it adds an checkbox menuitem into Project menu. When checked, this expert automatically adds compressed map file into executable when project is build. Now the problem is, that because this expert alerts executable right after build, map file and executable file do have slightly different datetime which causes profiler to report "Map file found, but too old". Could you change it so that small difference, say 1 sec, is allowed? Second, there seems to be no way to save profiling results for later investigation? Ideally, I would like to be able to create shortcut like SamplingProfiler.exe c:..MyApp.exe c:..ProfData.log So that users always run app through profiler which saves it's data into log file which I can later analyse. TIA ain Back to top Eric Grange Guest Posted: Tue Oct 11, 2005 10:31 am    Post subject: Re: ping Eric Grange : SamplingProfiler Posted an updated version in the attachments, tolerates a 5 sec delay between map/jdbg and exe (enough?), and also adds support for D2005 paths.

This was planned, but since I finally never really needed it, it never was implemented... maybe if/when I run into the need and the time...

How do you store profiling data in memory - do you keep it in the VT node or do you have separate data structure for it? Perhaps I (or someone else) can write functions to save / load this data so you only have minimal work to add this feature? ain Back to top Adem Guest Posted: Tue Oct 11, 2005 1:43 pm    Post subject: Re: ping Eric Grange : SamplingProfiler Eric Grange wrote: Quote: Posted an updated version in the attachments, tolerates a 5 sec delay between map/jdbg and exe (enough?), and also adds support for D2005 paths. It seems search/browse path information can not handle compiler directives. i.e. while SP can handle this stuff $(Delphi)Bin Apparently, this is hardwired as SP does not seem to be able to handle this: $(VCL)SynEdit where VCL is defined as 'Y:Components' in the System Variables. Could you add that please.

Profiling data is kept in a partially compiled state (a hierarchical structure 2 or 3 levels deep and a bunch of indexes and accompanying data), the stuff in the VT is computed on the fly from that data. Quote: Perhaps I (or someone else) can write functions to save / load this data so you only have minimal work to add this feature? You wouldn't be able to compile the units (dependencies to proprietary code) but I could extract the relevant type definitions. Not sure how much code would be required to get the UI to swallow it, mostly disabling/enabling the appropriate controls I guess... as long as you don't want to compare saved profiling runs side by side in distinct tabs, which I think might be what I was intending to do... and being a bit more work, one of the reasons saving profile runs didn't happen.

Didn't even knew $(VCL) could be used... where would I take its values? From the system environment variables? Or is there some registry key where its stored?

You create an environment variable pointing to a folder. This could either be a system variable (valid for all users) or user variable (a particular user, must be logged in). And, then when you encounter something like $(XXXX)SomePath The easiest is to use the Registry to decode this. Search for 'XXXX' in the following locations (and in this order) in the Registry. HKEY_CURRENT_USEREnvironment HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerEnvironment The value (which will be a string) corresponding to 'XXXX' is substitiuted for $(XXXX) to get the proper thing.

Yes, what I meant was that if you publish relevant type definitions someone would step up to implement functions to save and load this data into TStream.

The only part with no dependency would the debugger loop (straight from MSDN) and the call site identification code, rest from UI to statistics reuses proprietary stuff...

Then it would be easy to you to add this feature into project... Had a look at it and the streaming for stats has already been added here, so what remains would be sifting through the rest of the fields in the various profiling objects/forms to see what really needs be saved & restored. Quote: Yes, I was going to ask this feature too I thought that once saving / loading the data is working, comparing them shouldn't be that hard... but if you say that this is too much work then let it be. Would require a few hours to move the various code and fields to a frame/form that could be multi-instanciated, and then add whatever glue and extra UI controls necessary. So it's all a matter of finding those hours and the motivation :) Eric Back to top Adem Guest Posted: Wed Oct 12, 2005 8:40 am    Post subject: Re: ping Eric Grange : SamplingProfiler Eric Grange wrote: Quote: This could either be a system variable (valid for all users) or user variable (a particular user, must be logged in).

You've got me lost here... Where is the value of $(VCL) to be found? In the registry? (if so, which key?) or in the environment variables? :-) In Search/Browse paths, when,you encounter something like $(XXXX) what you do is this: ---- Strip off '$(' and ')'. That leaves you with 'XXXX'. ---- To find out what 'XXXX' stands for you'll need to search under (in this order) HKEY_CURRENT_USERSoftwareBorlandDelphi7.0Environment Variables '7.0' here represents D7, for other versions use appropriate values. HKEY_CURRENT_USEREnvironment This is for the current logged in user. HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerEnvironment This is where the global env vars are kept. ---- At the first occurance of 'XXXX' you stop since Current User may have defined a different override. The corresponding value is what you need to substitute for '$(XXXX)' [for all of it] in the Search/Browse path line that contained it. I hope it is by now clear that it does not have to be $(VCL), I could have used anything, such as '$(MY_DELPHI_CODE_PATH)'. It really is easier to do it than to put it in writing --for me, at least :-) I hope I haven't confused you even more.
