How should I create the server side to allow a unattended "Live Update" of client side apps?
Data Base ?
XML ?
HTML ?
Target File ?
Other ?

The only task of any server is -just as its name suggests- to serve client's requests. According to this, if you want your server to update your client, you should code your client so that it regularly sends update requests to your server and based on the server's answer your client should update itself.
You seem to have advanced with your email manager pretty far.;P

Hi Peter,
Rain all week here in sunny California 
The email manager is comming along well, at BETA 0.0.8.8.
Most big bugs are gone, but still worried about little ui situations.
The Spam Slammer module has some minor errors on edit rule.
The autoresponder allows per account config so arrays are getting confusing (to me).
The autoupdate is working abit, I loaded a ini file on the server and the live update mod check once a day for now anyway. Users may run live update by command or by allowing the application to handle it.
I have a line in the ini file that "tell's" the server side app when to check next, this give me a little flex if I can guage about when a new release is ready. also if I take a much needed vacation I may stick the line like [checkback]hours=240
The grabbing the data and loading it per your suggestion worked so very well, a user may be up and running in less than 2 minutes. Thanks to you!
The ini file on my Unix server strips the \r\n to \r so I am working on replace('\r','\r\n') dl on the fly.
I sort of wanted to use a database for the updates but the ini was a quick solution. I am downloading in one chunk since I know the size 256 for now, I am padding to meet chunk.
Any thoughts as always will be implemented.
Best Wishes,
Marty

If your "live update" is supposed to pass data only (the opposite could be: program parts, e.g.: a *.dll) then an *.ini file should do the job,
but a whole database, or *.xml file to pass would also be possible. You should make your choice depending on the data type. (Simple, linewise data: *.ini file; items with many optional attributes, structured data: *.xml or database)
As for the frequency of live update, you shouldn't overcomplicate your task. When your client apps get started (or at most daily), they should definitly check for an update and optionally you could leave the user a button for this, too.
The client's check for a newer version on the server should be as simple as possible. You could check for the availability of a file in the update dir on the server and download the new version, if the version number of this file is greater than the client's one.
Example:
http://server/update/versioninfo.txt contains only 4 bytes, the four digit representation of the version number. If this number is greater than the client's current version then the client automatically downloads http://server/update/newversion.ini which always contains the "freshest" info.
As you see a client's daily check is not more than downloading just 4 bytes from your server, which (provided you dont have zillions of clients) is not a huge network overhead.
Maybe then you could also increase the duration of your much needed vacation to over 240.

Hi Peter,
or is it Petro?

Move here we may float away but we will be warm!

Yes, I believe so, the ini will surfice in that it is only a (catalog)or (dictionary) of updates not the update itself.

Yes, the product (at this release) is a BroadBand product, in that I do not check for ras. I am pretty dissatisifed with the current pd ras classes so I am waiting to write my own.
The update.ini gets it's name from the app which gets the same name from another ini. Same Name just passed in parms of PostMessage.
(NOTE The installer sets some default values in all ini's
Here is a small snip of the main apps ini
[PROXY]
PROXYUSERNAME=
PROXYWORD=
PTYPE=0
PPORT=0
USE=0
[UPDATES]
UFULLNAME=http://www.digitaltcp.com/updates/appname/appname.ini
USHORTNAME=appname.ini
UDAUTOPOLL=240 // update auto-poll
Here is the little server side ini file(s) contents.
[currentversion]
major=0.0.0.0
minor=0.0.8.8
dlfile0=
dlfile1=
dlfile2=
dlfile3=
dlfile4=
dlfile5=
dlfile6=
dlfile7=
dlfile8=
dlfile9=
restart=FALSE
....
The client also logs in to a special account with dl priv's only.
Since it is loggining in anyway I store the machine serial number.
I am using this for id not to spy, but I wonder if I should use it at all?
May I send you a cd with the BETA prj included?
I am happy you are on my side, the others are hurting without you, you are just way too smart!

I have a print preview window and want to zoom in or out
some. Where can I get some info on this?
Thank You

If youu look in the printing section here. My article on the multi page preview has support for additonal zoom levels. You should be able to zoom in on areas in code by using the code from the OnLButtonDown() and using your own point location and calling the relevant zoom function.

From the MSDN Library:
Return Value
Nonzero if the message was translated and should not be dispatched; 0 if the message was not translated and should be dispatched
I have a PreTranslateMessage function (with MFC) to catch some special keys (actually WM_SYSKEYUP). When my "special" keystroke arrives, I process it, and I don't want it to be further processed.
However, no matter what return code I give back, the message will be processed, i.e. the character arrives as if it had not been processed yet.
Modifying the MSG structure (the parameter of the function) yields nothing.
What can I do? Should I use another function instead of PreTranslateMessage? Which one?
Thanks

try it in PreTranslateMessage()
if (pMsg->message == WM_SYSKEYUP)
{
//do your things;
//return your bool;
}
else
return CDialog::PreTranslateMessage(pMsg);
Hello World!

I tried around, and just found the solution (quite trivial):
BOTH WM_SYSKEYUP and WM_SYSKEYDOWN have to be processed.
One of them has to do the "real" processing, the other nothing, but both have to return nonzero.
Thanks anyway.

I am wondering how to use a different res when compiling
two different project configs. I would like to change the
comments in the VS_VERSION_INFO resource in a dll project
that has A and W versions. I know this sounds petty but I
would like to do it.
Thank You

In the ResourceView tab, view the properties for a resource. In the prop sheet there's a Condition edit box, so enter a preprocessor symbol there (for example, _DEBUG, or you can make up your own). That turns into a #ifdef _DEBUG (or whatever symbol) in the .rc file.
You can change the defined symbols on the Resources tab in the project settings.
(Note: this is for VC 6, no idea how it works in 7 but it's probably completely different)

I've got an application which really needs a "House Doctor/Changing Rooms" type makeover. Can anyone suggest a solution that is relatively quick, easy and hopefully free? It looks a lot better when I run it in XP, but I want something a bit tastier looking in Win2K as well. Rather than do a load of searching, which I haven't got time for, I was just wondering if there's any sort of well-trodden path to take?

I don't know. I don't know the difference between using a theme or a skin. What do your suggest? I just want it to *look* better than just another Windows dialog-based application...

I guess Visual C++ is not a right tool for that purpose, I mean great user interface with less coding effort. VB.NET, Delphi, C# or Java can do fancy user interface with lesser effort than Visual C++.
My suggestion is go for VB.NET. It is RAD and easy. It could cater most of the MIS requirement.
Of course, you would need a .NET framework for that.
If you are not opting for .NET. You could try out Borland Delphi or C++ Builder which ease of developing nice UI as well.
Hope this helps.

One way to make w2k look better (without too much effort) is to fiddle a little with edges, borders, icons, bitmaps and colors. 3d? Client edge? Flat? Different colors on error, warnings, etc? Images on buttons? Other than that I have no real good advice.

Hi there!
I have a problem with the drag & drop feature. My situation is this: I have a dialog based program and I would like to drag & drop files from e.g. the Explorer window onto my program. This works fine IF I drop on the window! The problem is that I want to drop on my push button (to be able to distinguish it from another push button) but I can't get it to react on these buttons!
Could anyone pliz help me??????????

Hello World!
|
|
|
|
|

is it possible to hack togheter a dialog in a resource designer and then use it as the main window? CreatwWindowEx() doesn't seem to accept a resource and I've tried using CreateDialog() but can't seem to create the dialog as the main window.
|

Yes, dialog-based applications are quite common.

Hi all!
I am using win32(no mfc) and ado.
After I filter my recordset I can no longer use the MOveLast() and MovePrevious() functions... (MoveFirst() and MoveNext() functions are working).
What can be the problem?
Thank you for your future answers!
Well... I am a beginner ...
