What operating systems are you using? What kind of printer are you using? What version of word?

ping the other computer and use the ping as the deciding factor, but how do you get a ping from within your own prog?
Yes this is probably the best way. I think there are a few examples that put a GUI on ping on this site.
I was thinking why not get a 1 port network printserver connect that to the printer and leave it on all the time. I have used them in the past. You should be able to buy one for less than $50 on ebay.

I'm writing the code in WinME (ick) and putting it on a WinXP box. This is kind of why I want to keep the program really simple.

I fogot: the printer is an hp 5550...HP technical support just told me that is was a Word prob and told me to call the vendor.
|
|
|
|
|
The reason why I asked these questions is that I have never experienced this myself and I have (as a system admin) seen many different printer configurations. I don't see why the printer driver would cause an application to crash but a badly written driver could.

me neither...
I've tried upgrading the driver and reinstalling word a couple of time to no avail. Besides why would Word be in communication with the printer while i'm typing?

Hi everyone!
I wonder how to associate my own extension to the program that I build.
For example I have saved a file as MyFile.ext. When I double-click the file in explorer I want to start my program and load the file. I do not use serialization.
The program is written in VC++6.0.
I appreciate any help

When you create a new SDI or MDI application with AppWizard, it creates a .REG file that will register your app's extension.

I am creating several windows using the Create function within Visual C++(MFC), i plot a graph on one of the windows and need it to be updated regularly, as I am implementing a tooltip feature where the mouse can be moved over a point and then the value of that point is displayed. The problem i am having is refreshing the view when another value is displayed, as it keeps displaying the previous values on top of the graph which also means the graph cannot be viewed easily. Any ideas on solving this problem, I tried using Invalidate and UpdateWindow with no luck

Hi friends,
anybody knows how to Hide a file or folder programatically? I meant, I need to lock that file/folder with password and invisible also.Even if the windows explorer properties set to show hidden items.

This (i.e., setting permissions) can only be done with an NTFS volume.

Wouldn't this kind of defeat the purpose of Explorer being able to show hidden files? There is no super-hidden attribute.

Hi.
I was wondering if anyone ever wrote a class that handled a CSV-file.
All data is seperated with a comma.
A single line can look like this:
"1234", "MyName", "MyFirstName", "1970-02-15"
The class needs to parse this data. For example checking what the type of data is. (first numeric, 2&3th text, 4th: VALID date (year-mm-dd))
Date needs to be validated too ofcourse.
Anyone can help?
Greetings
Jens

I have been reading in a file using the getline function and using a (,) as a delimiter.
I made a string caled name.
string name;
Then I do a getline(fin, name, ',');
I need to put the names in a char array. I thought I was doing that until I needed to use the names and I was getting garbage instead of the names I thought I was putting in the char array.
I was doing this to add them to the array which gives me junk.
Names[i] = stdup(name.c_str())
How can I read in a list of names 3 - 8 characters long and store them in a char arrray?
I can't have an array of strings because of other constraints.
Thanks,
Steven

Where's the CString problem here?

If you can be sure that you have enough space in your Names[i] field, then do
strcpy(Names[i], name.c_str()); instead of
Names[i] = strdup(name.c_str()); I seem to remember that your Names definition was an array of chars, in which case this would work.
Hope this helps,

Hmmm, I think it was an array of 45 char pointers, which made little sense since (!) the numeric members of that structure were NOT arrays.
Edit: Looks like we were both right. In one post he had
struct TSimHeader
{
char Name[45];
...
}
and in another he had
struct TSimHeader
{
char *Name[45];
...
}

You have a good memoy,
But if you rememeber, I have to actually put the chars in the array and not just the pointers because the array is getting sent to another PC. The recieving PC would have no use for the pointers on my machine.
here is my structure.
struct TSimSignal<br />
{<br />
int SimWriteFlag;<br />
int DisplayReadFlag;<br />
double Value[45]; <br />
double TimeStamp;<br />
<br />
}static TSimSignal_arr[1];<br />
<br />
<br />
struct TSimHeader<br />
{<br />
char Name[45];<br />
char Unit[45];<br />
double Min[45]; <br />
double Max[45]; <br />
int SignalCount; <br />
int SimStatus;<br />
<br />
}static TSimHeader_arr[1];
Once again back to putting junk in the char arrays (Name and Unit)
thanks,
steven

TSimHeader header;
strcpy(header.Name, name.c_str()); Should do the trick. If you're sending an array of TSimHeader's then you'll have something like this:
TSimHeader headers[10];
strcpy(header[0].Name, name.c_str()); Similarly for other members of the array.
Hope this helps,

Ryan,
When I use the strcpy() function I get the error:
D:\.......cpp(105) : error C2664: 'strcpy' : cannot convert parameter 1 from 'char' to 'char *'
Conversion from integral type to pointer type requires reinterpret_cast, C-style cast or function-style cast
The array that I am trying to put the ;name in is a char[].
Any Ideas?
Stevne

Post the definition of Names. That will help

Question 1.
I am not able to set CLIENT_EDGE for the dialog programmatically.
I used modifyEx() to set the style. But this did not work. Can any one tell how to go abt to get this done.
Qusestion 2.
I have written a DLL, in which a variable of type CString is set to some value. Setting the value for the variable is through an exe. This exe also displays the value of the string.
Can i display the value of the variable in the second instance of the exe i,e i have an exe by name Display.exe, i will run this Display.exe and set the value for the string. Again i will run another Dispaly.exe(Now i will have two similar exe on my desktop.) through which i want to display the contents of the string. I should use thread for this.

I`m creating an application which uses MSAccess. The application is written and with VC 6.0/SP5 and DAO-SDK 3.6.
When creating the database with MSAccess 95 everything works fine.
When creating the database with MSAccess2K I get the message that this is not a valid database. I also get this message, when I convert the working '95 database to 2K.
I assume, that I have to alter the header files or the alike (and recompile the whole library), to get the application working with MSAccess2K.
I remember having read about this elsewhere in the internet, but cannot remember the location.
Can someone help me. Either by telling me, where to find the information, or providing some hints, what to do?
Regards
G. Steudtel

Use the following line before using any database routines:
AfxGetModuleState()->m_dwVersion = 0x601;
Once this is called, you should be able to open a MSAccess 2000 version database.

Hello all
I'm developing an application which uses serial port. I want to code this application in such a way that if any other application is already using the serial port, I want to stop the other application before my application can proceed.
So I would like to know if there's any way of retrieving info reg processes using serial port. If any one knows how to do it please help me.
Thanks for your time
Hari.
