There are two different versions of GetPrivateProfileString, one for ANSI strings and another for wide/Unicode strings; so you'll need to specify that.
Your destination buffer should also be a StringBuilder rather than a string.
There is a utility posted on GotDotNet that will generate the correct DllImport statements for you. You need a copy of the win32api.txt from VB6 though.
HTH,

I don't know Chinese so I asked babelfish to translate for me, but it still isn't making much sense for me :-P
Tender: Realizes MSHFlexGrid with C# This company is the domestic well-known software
company, because of the item urgent need, programs the master to the society tenders, develops
one realizes completely the MSHFlexGrid function controls, requests to realize with C#. Concrete
and the time limit for a project price may speak face-to-face, and signs has the legal effect the
economic contract. Contact method: ywc@ufsoft.com.cn
Could you clarify? It looks like you are looking for someone to write a program for you but the translation gets terribly jumbled.

I think it's not bad to take a look at "managed C++" part,
I think your answer is there.

Hi all,
I've got a DataRow inherited class like this:
public class CustomDataRow : DataRow
{
new public this[string columnName]
{
get
{
[...]
}
set
{
[...]
}
}
}
When compiling, Visual Studio shows this error:
"No overload method for 'DataRow' takes '0' arguments"
I tried to add a default constructor like...
public class CustomDataRow : DataRow
{
public CustomDataRow()
{
}
new public this[string columnName]
{
get
{
[...]
}
set
{
[...]
}
}
}
...but error continues. Any idea?
Thanks in advance.

DataRow does not have any public constructors, therefore your cannot derive a new class from it. This situation exists for many classes in System.Data and System.Xml namespaces.

Hi All,
I have a application created in C# that is working 100% on my Windows 2000 Prof with no bugs at all.
I have installed it on a NT4 machine with SP6 and most things still work but I am getting a few bugs.
For example.
I have some code that must run when a dropdownlist is changed.
On NT4 if they select something in the dropdown everything works fine, but if they drop the list and then click somewhere else they get an application error.
I cannot replicate this problem on my Windows 2000 box?
Can someone let me know why this happens?
Thanks,
Gavin Mannion

I can store some kind of datatbase in XML files.The question is here:
In what condition it is better to use XML and when should I use Access/SQLServer database?

It is roughly the equivalent to ask if you should use a comma separated file or a database.
Let us compare the two file types:
The XML file would have the possibility of bearing the meta information itself, but it is up to the designer to give the tags some meaningfull names.
If you use a dtd for the xml file, you could put the meta information here, but again, it is up to the designer to do so.
At the risk og getting flamed: IMHO XML files are glorified comma separated files, and the serialization process compared to (almost every) dbms is slooow...
Databases on the other hand, are containers designed for their respective dbms'es to give a balanced performance of searching, inserting, deleting and serializing and they are built for handling VERY large amounts of data.
Internally they keep some basic indexes on the position of data, and in exchange for resources like disk space, you can ask for extra indexes to improve search speeds.
Conclusion: If you are in need of serializing SMALL data portions, like 1-2 MB, you could use an xml file. But if the data portion will grow virtually unlimited or you are doing a lot of insertions/deletes that causes serialization, then you should use a database (even Access is able to compete here).

Hi everyone:

My select statement looks like this:
string str="select t1.amt,t2.Name,t3.Desc from t1 left join t2 on t2.ID=t1.ID left join t3 on t3.ID=t2.ID";
When I execute ExecuteReader() I' getting an error.
With only first join it's OK, with only second join it's OK but with joins there is exception.
Is this syntax incorrect for two joins?

In terms of capabilities, they say VB.NET and C# is the same. So what about speed? Which is faster?
|
|
|
|
|
neither is faster
both languages compile to the same IL, which runs at the same speed regardles of what language it was compiled in.
|
|
|
|
|
thanks,
that makes sense.
But compared to both of them how fast is c++ (10 times faster? maybe?);)
|
|
|
|
|
IL executes at roughly 80-90% the speed of C++ because it is native code, not interpreted like Java.

Oh! This is driving me  . I have a windows service written in C# and .NET. All it has to do is write an xml document based on the information found in the system, for every 5 seconds. So I have a timer and a GetInfo function. This function is called by the Elapsed event of the timer (every 5 secs). And I have included everything in try...catch block. In my catch block, I catch any exception thrown and store in EventLog.
I am getting a lot of problems.
1. The service is not starting. When I start it using the Services Manager, it will attempt to start and end up saying "Service could not be started in a timely fashion".
2. In some test machines it starts although, its not writing any xml nor any EventLog Exception entry. I checked my code thoroughly and is just working ducky in my development machine.
Is there some security issue that I need to consider while running this service? (I am running the service as LocalSystem account). How would this affect accessing Eventlog or writing an xml doc...???
Any suggestions/..
