I have Windows XP with all latest updates installed.
I have MS Office 2003 installed.
When I start Access .mdb fail, I get:
"Security Warnings: Unsafe expressions are not blocked"
"Microsoft Jet 4.0 Service Pack 8 or later must be installed to block unsafe expressions ..."
When I start to install Jet 4.0 SP8 Update (for Windows XP) , I get:
"Setup has detected that the Service Pack version of this system is newer than the update you are applying"
what newer updates should I apply to block unsafe expresions?

I'd ensure that you have Office 2003 Service Pack 2 installed. I don't know if this will get rid of the error, though. Windows XP SP2 includes a newer version of Jet 4.0 than the downloadable SP8.
Office can sometimes be vulnerable to security issues and you should ensure that you keep it up to date. Microsoft Update[^] includes updates for Office and other Microsoft products in addition to updates for Windows.
Stability. What an interesting concept. -- Chris Maunder

I used to challenges before. This problem occure only when i try to open the previous file in office 2000 or office xp which contain any code in module that i wrote by myself. In my opinion, i think this problem occure because of access 2003 might has a built-in security feature that check the previous file version for any code that might be affecto the system.

hi,
I have a problem with my system performance ,its very low.sometimes virtual memory low icon is appearing in the startup.I think it may be because of my 128 mb ram as I have installed vc2005 and MSDN.Now what I want to know is if we increase virtual memory in our pc will there be any problem if so by how much amount can i increase my virtual memory.
Any suggestions will be appreciated.
Thanks

Increase your virtual memory is increase the space of your hard disk drive as a temporary memory. I also used to increase the virtual memory in my computer and didn't found anything change.

There are a rank of minimum virtual memory and maximum virtual memory. The minimum of your virtual memory is = RAM * 1.5 and the maximum of virual memory = RAM * 3. In this case, if your computer have 128mb RAM then the minimum of your virtual memory would be 192mb and your maximum virtual memory would be 384mb. So you can increase to any number that you want. But if you want your system to run a fast performance, you should move your PAGEFILE.SYS to another free partition.

128MB?  That is far too little to run an NT-based OS + VC 2005 at any decent speed, as you've found out. Increasing your page file size won't help the speed any, buying more RAM will.

If i have a second partition with free 20Gb drive, and i move the page file to this drive and increase to page file size of 15Gb. Will this computer run faster than before?

Even if you increase virtual memory it wouldn't increase performence. By default setting, windows chooses automatickly size. If the ammaount of required memory is larger than amaunt of RAM + Virtual memory, windows automaticly increase its size. RAM exist as memory, because it's a lot faster than Hard Disk. If HD would be a lot faster than a RAM, then there wouldn't be any point of having RAM. On other words, if RAM is not enough then it is using Virtual Memory. When It uses Virtual Memory, then HD will be very active, even after is loaded.
To run VS 2005, it requires Windows XP. XP can run on 128MB of ram, but to run XP in descent speed you will need 256MB. For VS 2005 to run a descent speed you wuld neet at least 512MB

hi all
iam working on WMI . iam trying to write an application for Event notification.
Iam usimg Win32_Process class, and ExecNotificationQuery for WQl query.
Iam trying to display a message when a new process is created.
my WQL query is
hres = pSvc->ExecNotificationQuery(
bstr_t("WQL"),
bstr_t("SELECT * FROM __InstanceCreationEvent WITHIN 5 WHERE TargetInstance ISA 'Win32_Process' And (TargetInstance.Name = 'notepad.exe' OR TargetInstance.Name = 'calc.exe' ) "),
WBEM_FLAG_FORWARD_ONLY | WBEM_FLAG_RETURN_IMMEDIATELY,
NULL,
&pEnumerator);
if iam not wrong ,After executing this query TargetInstance will be Instance of WIn32_process class.
and now iam trying extract data usoing this statement
hr = pclsObj->Get(L("TargetInstance.Name"), 0, &vtProp, 0, 0);
but iam not able to get value of Name property of Win32_Process class into vtProp where vtProp is of type VARIANT.
IWbemClassObject->Get( LPCWSTR wszName,LONG lFlags, VARIANT* pVal,CIMTYPE* pvtType, LONG* plFlavor) is used to retrieves Specified property value.
but here iam using it for getting value fron an istance i.e TargetInstance.Name. Is it the correct way to do if not please help me in extracting value of Name Property.
Please help me in solving this .
Thanks in advance

This is not an O/S question, but instead belongs in the Visual C++ forum.

Hi!
I had download the source code of mass storage device driver for windows98 from Microsoft websit.And builded it with 98ddk on windows98 system,and then
installed it on win98 system. It can work correctly all the time.
If I suddenly remove the device from pc when copying file from pc to device or from device to pc on win98 system,the blue screen occur,and i have to restart my system.
But if do the same on win2000 or winxp there is no blue screen.
Now i wanna modify the driver source code to avoid the blue screen when suddently remove the device while it is exchanging data with pc on win98 system.
My question is:
1,If my hope has the possibility to come true?
2,If has,then which part of source code of this drive should i have to modify,and what couses the blue screen?
I know that in the source code it just abort all the pipes when device remove sudently but nothing else.
Thanks!

there no need for cross-posting the forums...
if you don't get any answer, it may be because :
1. you don't let people the time to answer
2. the question is not well formulated
3. no one knows...

Hi!toxcct,
Thank you very much!
My quetion is:
If there has the possibility to avoid the blue screen when
suddenly remove the pen disk from pc while copying file from
pc to pen disk on win98 system?
thanks!

yeah, i understood the question... i only said that there was no need to ask it many times on many forums at a time.
well, for your question, i am not sure about the answer, that's why i didn't let you my thought.
i actually think that there's nothing you can do again that blue screen under Windows95/98/ME...
but i may be wrong.

"i actually think that there's nothing you can do again that blue screen under Windows95/98/ME...

yeah,i think maybe you are wrong. Couse the usb pen disk driver can do more work after the pen disk removed suddenly.
So what about your opinion?
thanks!

This is by design. Ultimately if you do this enough times it will ruin the USB "Pen" drive.
The operating system mounts a virtual file system and needs to unmount it to leave the memory on the "Pen" drive in a useable state. Things that trigger a Blue Screen that are obvious (like this) probably should not be repeated. This is not a software problem it's hardware.
I only read CP for the articles.

Hi! Code-frog,
Thank you very much!
If I do the same on win2000 and winXP it never trigger a Blue Screen.
I know that Win2000 and WinXp have their own USB pen disk drivers.
I can not understant that it's a hardware problem but not a software.
So what couses the difference phenomena on win98 and win2000(WinXp)?
Thanks!

It's really a moot point. "Surprising" the driver with an unexpected removable of the device will result in data corruption. You just don't do it.
If the volume on that stick is not dismounted properly, you stand a LARGE chance of corrupting the contents of the stick. Then, a Blue Screen of Death will be the least of your problems.

Hi! Dave,
Thank you very much!
Yes,except testing my driver I never remove the device whilt it exchage data with pc,but I can never sure about that my customer never do it.
I wish my customer can use my pen-disk on win98 system just like they use it on win2000 or winXp system.
So,sir,pls give me your suggestion.
Thanks!

No ideas, cause I haven't written for 9x systems in a VERY long time, and never a device driver.
You're talking about writing a device driver for a system that hasn't been supported by Microsoft in ages. Help on this is going to be extremely difficult to come by, if for no other reason, no one has anything to test the code on!
