    <p>i'm trying to read information from <a href="http://www.techpowerup.com/gpuz/" rel="nofollow">GPU-Z</a> shared memory, but i'm doing something wrong. I've managed to translate the shared memory structure posted on <a href="http://www.techpowerup.com/forums/showthread.php?t=65258" rel="nofollow">TechPowerUp</a> forums. I can read all the <code>GPUZ_RECORD</code> but not the <code>GPUZ_SENSOR_RECORD</code>. Any help will be apreciated. Thank you!</p> <p><strong>LATER EDIT I:</strong></p> <p>if i use <code>packet record</code> instead i don`t get the AV anymore, but i still can't get the sensors info.</p> <p><strong>LATER EDIT II:</strong></p> <p>If i read the <code>data</code> from 0 to 128 (129 elements), then the 128 element is the first sensor and i can see the data correctly. :( </p> <pre><code>const MAX_RECORDS = 128; GPUZ_RECORD = record key: array[0..255] of WChar; value: array[0..255] of WChar; end; GPUZ_SENSOR_RECORD = record name: array[0..255] of WChar; units: array[0..7] of WChar; digits: Cardinal; value: double; end; GPUZ_SH_MEM = record version : Cardinal; busy: Boolean; lastUpdate: Cardinal; data: array [0..MAX_RECORDS] of GPUZ_RECORD; sensors: array [0..MAX_RECORDS] of GPUZ_SENSOR_RECORD; end; PGPUZ_SH_MEM = ^GPUZ_SH_MEM; </code></pre> <p>//~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~</p> <pre><code>procedure TMainForm.readSensors; var hMapFile: Thandle; sKey, sVal: string; GPUInfo: PGPUZ_SH_MEM; s, d: integer; begin hMapFile := OpenFileMapping(FILE_MAP_READ, FALSE, 'GPUZShMem'); if hMapFile &lt;&gt; 0 then begin log(['Mapping succesfully']);; GPUInfo := MapViewOfFile(hMapFile, FILE_MAP_READ, 0, 0, 0); // ShowMessage(IntToStr(GetLastError)); if GPUInfo &lt;&gt; nil then begin log([ GPUInfo^.version ]); log([ GPUInfo^.busy ]); log([ GPUInfo^.lastUpdate ]); log(['LOGING DATA ~~~~~~~~~~~~~~~~~~~~~~']); for d:= 0 to Pred(MAX_RECORDS) do begin sKey := GPUInfo^.data[d].key; sVal := GPUInfo^.data[d].value; if sKey &lt;&gt; '' then log([d, '#: ', sKey, sVal ]); end; log(['LOGING SENSORS ~~~~~~~~~~~~~~~~~~~~']); for s:= 0 to Pred(MAX_RECORDS) do begin sKey := GPUInfo^.sensors[s].name; // i get an AV here when s:=127 log([ 'Sensor ', s, '#: ', sKey ]); // sVal := TPN^.sensors[s].units; // log([ 'Unit: ', sVal ]); // log(['Digits: ', TPN^.sensors[s].digits ]); // log(['Value: ', TPN^.sensors[s].value ]); end; end else log([ 'Could not map that zone!' ]); end else begin log(['Could not find the zone for mapping...']); UnmapViewOfFile(GPUInfo); CloseHandle(hMapFile); end; end; </code></pre> <p>log() is a small procedure defined like this:</p> <pre><code>procedure log( vData: array of Variant ); </code></pre>

    1. COSo GPU-Z is a benchmark program and you're accessing shared memory via a memory mapped file? A bit of background would make your question a bit less of a mystery. You really expect people here to figure out what you're talking about without explanation? Help others help you.

    2. COWell, i thought GPU-Z is a very well know video card information program, seems my assumption was wrong, i`m sorry. My problem is that i can`t read the `GPUZ_SENSOR_RECORD` right for some reason. Maybe i didn`t translate the shared memory layout correctly.

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.
