I'm running IQ Feed 4713 with IQ Link. I also have Quote Tracker running. IQLink feeds data to an Open Office spreadsheet using DDE. When Link starts it is using 16 GDI's. It gradually increases GDI's to a very large value (4,000 or more), slowing down the operation of Windows 7 64bit. User Objects also increases.
I currently have 279 symbols active. Any ideas on what is happening? Bud Schoen Kailua, Hawaii |

I can't think of anything in IQLink that would be creating GDI objects other than the status dialog but that shouldn't be the cause of what you are seeing.
You mentioned that it gradually increases. Over how long of a timeframe do you see this happen? |

Yes, why GDI is used is a good question. It starts with 16 then increases slowly one by one. I thought it might have something to do with Quotetracker running, but I ran only the spreadsheet and it does the same thing.
Eventually I have to stop the spreadsheet, kill IQLink, then start over. Annoying! Bud Schoen Kailua, Hawaii |

Can you tell me how long of a timeframe you are looking at until you see it increasing?
I am not seeing the same thing here but then again, we are now after the market so that might have something to do with it. Also, I am feeding into excel instead of OO but that really shouldn't make a difference either. |

I tried shutting all down, then starting IQLink. It came up with 16 GDI Objects.
I then started the spreadsheet and clicked on update links. I didnot bring up the window that shows the connections as I usually do. The GDI stayed at 16, the User Objects went up to 1776. Although it's after hours, some data is coming in and it's still stable at 16 GDI. I opened the IQLink Statistics window and the GDI is now increasing at about 1 per second. Hopefully, that should be easy for the programmers to find. In the meantime, I'll be careful to not open that window. Let me know what happens. Bud Schoen Kailua, Hawaii |

Oops, I should have mentioned that I closed the window immediatly.
It's still increasing, now up to 172, window definitely closed. Bud Schoen Kailua, Hawaii |

Unfortunately, at the current time, I can't duplicate it. I've had the status window open for nearly an hour and it is still sitting at 16 GDI objects.
Can you post which symbols and which fields for each symbol you are watching? Or can you post your OO workbook (you will have to zip it)? |

Would be hard to send my sheet, here's what I tried:
1. Start IQLink, noted that there were 16 GDI. 2. Opened blank oo calc sheet. 3. In col B2 typed =DDE("IQLink";$A2;B$1) 4. In row 1 put Last Change Volume 5 in Col A put in a partial list of SP400 symbols 6. Copied B2 to all other slots. Have about 50 symbols with values in them 7. Opened IQLink window.\ 8. GDI now increasing at about 1 per second, maybe slower than my sheet. I'm running Win 7 Professional 64 bit with 2.2G 4 core processor, 8 GB mem. Can you duplicate using oo Calc? I don't have Excel on this machine. Bud Schoen Kailua, Hawaii |

Bud, I was able to duplicate this but it required duplicating your exact setup. Meaning, it doesn't seem to happen on any other OS than Win7 (I only have 64bit so I haven't tested on 32bit Win7).
This doesn't seem to happen on 32 or 64 bit Vista. I will add this to the list of issues to look into for IQFeed. |

Interesting. I have Win7 32 bit on my laptop but I don't want to try it now since I'll interupt the IQFeed now on the 64 bit machine. This afternoon I'll see what happens on the laptop and post it here.
As long as I don't open the IQLink window all is fine. Bud Schoen Kailua, Hawaii |

Ran some more tests:
1. Ran same setup on laptop, Win7 32bit. Had IQ ver 4403. Same result. Kept increasing even after Calc shut down. 2. Ran Win XP on desktop. Had IQ ver 4607. Started w/ 17 GDI. When window opened started increasing. Kept increasing after oo Calc shutdown. 3. Downloaded IQ ver 4720. Still on XP. Same w/ oo Calc. 4. Went back to Win7 64 bit. Tried running similar app using Quatro Pro 8 spreadsheet. Still increases when Link window opened. Looks like it's not tied to oo Calc (I don't have Excel) but the older Quattro Pro is different than Calc. Also it's there in previous versions of IQFeed. I don't have Vista (thank goodness!) Perhaps it's the climate in Hawaii? Windows grow better here. Bud Schoen Kailua, Hawaii |
