I'm a little puzzled about the error message but it appears as if you've defined the same variable in those two files.
1. Rebuild the whole project.
2. If that doesn't fix it, take a look at this related explanation I wrote about a while back.

Part of the project that I'm working on is placing text over the child window. The user must be able to set font, resize and move text "object" inside the child window client area at any time.
I succeeded in creating transparent window with some text drawn inside, but window repainting is absolutely unpredictable and it is effecting the whole application.
Any suggestions/ideas on this subject?
Thanks in advance

Transparent windows are not actually transparent, they just don't redraw properly. They are, as you say, unpredictable.
I did this in a paint type package, and I just kept a vector ( an array ) of structures that told me what string to draw, in what font, and the bounding rect to all me to select items when they were clicked on.

Maybe the simple way is better: draw text in child the window itself using TRANSPARENT background mode?

Christian and Alex, thanks for your input.

I hope this is an easy one....
How do I get the time between clicks that counts as a double-click?
I can find the allowed difference via GetSystemMetrics(...) but I can't find the time. I hate hard coding this type of thing.....

It doesn't happen often but Microsoft actually came up with a function with a good name for this: GetDoubleClickTime.

Hi,
Is there any sample for resolving folder shortcut to a network path. Or to a app (full path name)? It has to be supported on NT/2000/XP. I'm aware of IShellLink.
Thanks

|

i can use the API "EnumProcess" for get all identifiers for each process object in the system. but how do i can get the full path for the particularly process?
thanks for your help!!!!!!!!!!
My english is poor, please pardon.

Hi,
When you sort columns in Windows explorer on win XP, it highlights the column being sorted. Any idea about “how to” for this?
Thanks

Maybe that's a built-in feature of the v6 common controls? But if not, you can do it yourself with custom draw.

It is not built in feature of commctrl 6. any other options beside custom draw?
|
|
|
|

Custom draw is perfect for customized drawing like that. The alertnative is owner draw, which is overkill for what you want to do.

I am using this component to retrieve disconnected recordsets to an ASP or VB client. I pass in a SQL Statement and return the disconnected Recordset.
Under COM+ Component Services, I created and application and set the following properties: Object Pooling, IObjectConstruction, JITA, Transactions are set to NOT Supported. I do not plan on using transactions in my project.
The Example I followed (Alan Gordon's) to build this DID NOT include the IObjectControl Interface.
I added, you can see that its references are commented out. (The component runs fine with and w/o the IObjectControl declares.
The component appears to function properly. Of course it has not really been stress tested.
My question to you is??? Is this properly coded?? I read in Tim Ewald's Transactional COM+, that you must use IObjectControl if you are using ObjectPooling and JITA.
Is this true? Could you take a quick look over this and give me your opinion? How would you code this differently to ensure that IObjectControl is being used properly with ObjectPooling and JITA. If you need to see the whole project, I can send it to you zipped.
Happy Holidays !!
Sincerely,
Peter J. Santiago

hiyaz, will anyone tell me how to make the code in a post look orange like that???  it'd be handy and flashy

Enclose it in <code> tags, like this <code>some code</code>. If you have lots of code and not just keywords, do this;
<pre>
int main() {
printf("hello\n");
}
</pre>

Can I use sql string?
whoi can show me how to do with it?
thank you for your help!

Hi there,
It depends how much data and what database you're using. With most databases there is support for a RAW type of data that lets you store huge amount of binary data in a record.
Usually strings (or VARCHAR in most cases) would not be such a good idea for more than a couple of kilo-bytes (limitations depend on the database vendor and the middleware used to access it)
HTH
Cheers,
Pierre

I use ACCESS,the data ia about 5~8M
|
|
|
|
|
ACCESS... Arggh
There is not much support for big chunks of Data with Access. Text is a no-no as it is limited to a stupid 255 characters.
There is the memo type but that's no good either as if I remember correctly it is limited to 64k
I think the only type you can use is OLE (which, if I remember correctly can store up to a Gig of data). Not sure if that's supported by all versions of Access, though.
HTH
Cheers,
Pierre

Some databases call the type for binary data "BLOB" (Binary Large OBject) instead of "RAW".

Strings are unsuitable for binary data independent of size, because the DBMS may do character-set conversions etc. if it thinks the data is a text string, and mangle your binary data.
