I am fresher just before 1 month i joined a IT company. Here i am working on VC++. I want to load two different XML files in VSFlexGrid_1 and VSFlexGrid_2 respectivelly and i need to compare the both xml files. If any mismatch found in the both files it should display in red color and if element not found in any one of xml file it should leave one blank line. I hope you know how the Beyond compare application works. like same my application should work. please help me to code for it.
hello guys... i have got this static library "myLib".
Now in this library, classes are declared but their respective definitions are separate files (with the names of classes). There is also "stdafx.h" file inwhich necessary files are already included.
This library builds successfully but the problem comes, when I include this library's "*.h" file into my client project. Im getting annoyed by these errors. Some of them are as follows
- error C2504: 'CObject' : baseclass undefined ...
- error C4430: missing type specifier - int assumed. ...
- error C2143: syntax error : missing ';' before 'protected'
- error C2146: syntax error : missing ';' before identifier 'm_evtComplete'
Im getting no less than 159 errors. But as stated earlier, thid library builds successfully. Any ideas??
From what I understand about RTX, the RTX specific functions are similar to, but do not overlap the Win32 functionality. However, I believe you can still call the Win32 functions from withing your RTX specific program. In this case, you'd have to call OpenEvent().
First I want to say that I am 100 pages into Beginning Visual C++, so I have basically no exp. All of my programming has been VB, C# and if you are over on the PHP side you'll notice I'm starting that and not very good yet
Anyways, this is the problem we have where I work. We are moving from Visual Studio 6 to 2010 (slight jump) and are running into some problems with speed. For example I can write a app in VB to read from a database and put the data into a DataSet in about .4 seconds. To do a similar operation in C++ is taking 5 seconds (not .5 but 5).
VB Code is as follows to fill the dataset
sqlString = "SELECT * FROM attyesqs"
da = New SqlDataAdapter(sqlString, objConnection.cnn)
If you know VB we are talking very simple and it works well.
However our other programmer who is trying to get similar performance out of a MFC app is running into the problem of it being 4.5 seconds slower. He is using a DSN and ODBC
not being familiar enough with C++ I don't know what part to post here, but the connection he is using is as follows:
I'm actually grabbing more columns in my query but that shouldn't matter much, I think it's only like 2 or 3 more. With VB and C# things have changed greatly in the last 10 years, is there now a better way to do this in C++/MFC? I can try to answer any questions you may have, and as always thank you in advance!
If I remember right the SQLConnection I'm using in VB is basically ADO? I've been doing some reading and from what I've been finding people are saying that DSNs are "now slower than dirt", is this the case or just a case of them not being used properly? If they dropped intellisense support for ADO am I to believe that this is something that is going to be gone in the near future and replaced with something else? Again new to this side of things so excuse my lack of knowledge. Thanks again.
