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

Could you clarify? It looks like you are looking for someone to write a program for you but the translation gets terribly jumbled.

I have main program written in C++.
This is unmanaged code from VC++ 6.0
now compiled in VC++ .NET.
How to import C# function to
this C++ unmanaged code.
Thanks

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:
I will given a OMG idl file and wanna build a object tree according to it.
Is there any free or cheap tool to make me bind the idl to cpp or C#?
Thank you

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/..

Hi omkamal:
Well i am running thru the same scenerio my friend. I am logged in as Local Admin on my win 2000 prof box and installed a .net C# service as LocalSystem account. When I try to start the service it hangs on and gives me that standard error, that is, "Service could not be started in a timely fashion".
What all things do u need to take care or what are the prerequisites for a successful service install and start up? I even tried creating a basic service and tried starting it but gave me the same stupid error message!!
Thanks,
Rakesh

Hi,
I am attempting to use declarative code access security to protect
my C# web application. I am using
[UrlCodeIdentityPermissionAttribute(SecurityAction.Demand, Url =
"http://www.microsoft.com")]
outside of the main class in my dll.
I understand that this means that if a website other than Microsoft
calls my dll code they should be refused access to the protected class
- an exception should be thrown. When I call my dll code from another
program, access is always granted.
Is my understanding of declarative code access security incorrect?
What am I doing wrong? Any help would be greatly received. I am new to
this area and am finding it difficult to find code examples of such
code. Examples of imperative security would also be useful
Thankyou,
Kerry

I've spent a lot of time playing with my datagrid control and its associated datatable, and I think I did it all wrong. My scheme is way to complicated. I read a user defined data structure in from a file, then fill out the datagrid from it. Then I track any changes to the datagrid, update the datagrid to reflect these changes (these former two steps are giving me too much trouble, prolly b/c my overlycomplicated design), and then rebuild the structure from these changes. However, there seems to be some interdependencies in the updating of the datagrid that depends upon nonupdated information in the data structure, and it's all a big mess. 
My actual on-disk data format is XML, which is then parsed into the datastructure for program specific manipulations (calculating chess scores from a tournament database if you must know). I want my users to be able to create and edit chess tournament databases using this datagrid, which will then be mapped into the in-memory data structure for the calculation and manipulation, and finally saved to a disk in XML format. I have all the XML -> Datastructure and Datastructure -> XML stuff down, but the user input is really getting to me.
So, before I start with my datagrid all over again, I need to know how I'm supposed to do this. My current idea is:
+ Load the file into the data structure
+ Update the datagrid/datatable (I am using them as one, there's only one table).
+ Use the RowChanged event to determine when the datagrid is modified. If so, make those changes INSIDE THE DATA STRUCTURE. Then, after the datastructure is updated, set a flag so that RowChanged does nothing, and rebuild the datagrid from the beginning using the data structure. After it is rebuilt, set the RowChanged flag back so that it responds to user input. I want RowChanged to respond to userinput, but not to respond to itself. I will know this all works when I can throw any valid input into it, and get the same thing out, only now stored in the data structure. When I throw in invalid or incomplete (ie, half a row) input, it should not parse it at all, simply leave it there.
Sound good? There must be a standard way of doing this. I am completely new to all this database stuff.

I think the recommended way of working with data is through the DataSet.
You can load a dataset from xml (create a schema then specify where to load it from an the schema), then bind the dataset to the datagrid, once you are done editing you should then be able to save the data back to the xml file.
DataSets are a bit mysterious to me though; most of my data access has only been single read/writes so I've not had to worry about that yet
