Reading in Unicode text

Here goes, I'm trying to read Unicode text in from a ini/uni file.

I've made the call to GetPrivateProfileStringW

[DllImport("KERNEL32.DLL", EntryPoint = "GetPrivateProfileStringW",
  SetLastError = true,
  CharSet = CharSet.Unicode, ExactSpelling = true,
  CallingConvention = CallingConvention.StdCall)]
        private static extern int GetPrivateProfileStringW(
          string lpAppName,
          string lpKeyName,
          string lpDefault,
          string lpReturnString,
          int nSize,
          string lpFilename);

And this is what I use at the point of actual calling.

string returnString = new string(' ', 32768);
GetPrivateProfileStringW(fetchUniSection[n], fetchUniInfo[i], "FAIL", returnString, 32768, containingFolder + @"\BiblioSelfCheckDefault.uni");

I get the text, but rather than be in proper Chinese, Japaneses, Arabic, etc.. it is just garbage characters.
Can anyone tell me what I am doing wrong? As far as I can tell, it is taking my input and forcing it onto ASCII.
Thanks!

Hi,

AFAIK you need to pass a StringBuilder, not a string, for native strings that must be writable.
I have an article[^] in progress that shows an example.

After switching to StringBuild I now get

"Warning: A StringBuilder buffer has been overflowed by unmanaged code. The process may become unstable. Insufficient capacity allocated to the StringBuilder before marshaling it."

Forgive my lack of understand... But what does that mean?

---
I solved that by increasing the stringbuilder size.

Here is my new code, but I am still getting mangled results like below.

[DllImport("KERNEL32.DLL", EntryPoint = "GetPrivateProfileStringW",
  SetLastError = true,
  CharSet = CharSet.Unicode, ExactSpelling = true,
  CallingConvention = CallingConvention.StdCall)]
        private static extern int GetPrivateProfileStringW(
          string lpAppName,
          string lpKeyName,
          string lpDefault,
          StringBuilder lpReturnString,
          int nSize,
          string lpFilename);

StringBuilder returnString = new StringBuilder(5000);
GetPrivateProfileStringW(fetchUniSection[n], fetchUniInfo[i], "FAIL", returnString, returnString.Capacity, containingFolder + @"\BiblioSelfCheckDefault.uni");

Then I just use returnString.ToString(), store it in a string variable, and later I place it in a text box.
But in the text box, instead of the other language, I get

Hi,

I don't see anything that is fundamentally wrong.
I never used GetPrivateProfileString myself.

However:
- I would drop the "SetLastError = true" part, as I don't see anything about GetLastError in the MSDN documentation here[^]
- I trust your filename is ...BiblioSelfCheckDefault.ini not .uni

Hope this helps.

I dropped the "SetLastError" part, still the same results.
Actually the file is .uni not .ini, which as far as I can tell, .uni is simply an .ini file the denotes it can handle Unicode.

I guess I can manually sort through the uni/ini file and access the text that way and maybe it will be in proper unicode.
Thanks for the assistance!

Creating a Class that can be a list?

bbranded28-Dec-09 5:20

Hello,

I'm a little lost as to how to write a class that will take in arguments from the .Add function of a List<>.

With reference to this thread, I have written the following class.

public class SnapShot
   {
       private DateTime m_SnapShotDateTime;

       public DateTime SnapShotDateTime
       {
           get
           {
               return m_SnapShotDateTime;
           }
           set
           {
               m_SnapShotDateTime = value;
           }

       }

       private long m_BPSAverage;

       public long BPSAverage
       {
           get
           {
               return m_BPSAverage;
           }
           set
           {
               m_BPSAverage = value;
           }
       }

       public SnapShot(DateTime snapshotdatetime, long bpsaverage)
       {
           m_SnapShotDateTime = snapshotdatetime;
           m_BPSAverage = bpsaverage;
       }

   }

I have created a List and would like to use the .Add function to add "entries" for .SnapShot(DateTime snapshotdatetime, long bpsaverage).

SnapShot LiveSnapshot;
List<SnapShot> LiveSnapshotList = new List<SnapShot>();

//LiveSnapshotList.Add();

How do I properly write the class so that it handles the .Add function of the List? Or should I be calling .Add with some other overload value?

Thanks,

Matt

Hi,

1.
you don't need to create a special list class, a simple:

List<SnapShot> snapShots=new List<SnapShot>();
SnapShot snap=new SnapShot(...);
snapShots.Add(snap);
...
List<SnapShot> moreSnapShots=new List<SnapShot>();
moreSnapShots.Add(...);
snapShots.Add(moreSnapShots);

would work just fine.

2.
And you could make that slightly more user-friendly with an almost empty class like this:

class SnapShotList : List<SnapShot> {}

SnapShotList snapShots=new SnapShotList();
SnapShot snap=new SnapShot(...);
snapShots.Add(snap);
...
SnapShotList moreSnapShots=new SnapShotList();
moreSnapShots.Add(...);
snapShots.Add(moreSnapShots);

Thanks very much Luc. I will take a look into this.

As for snap, this is of the type SnapShot as defined via the SnapShot class's SnapShot function?

Thanks,

Matt

yes.
however functions are passé, you should call them methods now; unless they are constructors!

If you use List, then do not handle .Add, because it is implemented. As your example you incorrectly defined List.

List<SnapShot > LiveSnapshot = new List<SnapShot>();

public class SnapShotList : List<SnapShot> {}

Then you can do this:

SnapShotList snapshots = new SnapShotList();

As a result, you get all of the benefits of having a list (including all of the methods therein) in a conveniently named object, and you can add specific custom behavior to your class to handle circumstances ragarding the items in the list. I do it all the time.

I am developing a Custom Control and I will ask question from several categories. I appreciate your answers

1st question:
How can I create a class to be used like XmlNode. XmlNode can be XmlElement or other types. I wan't to use similar approach. I need it, because I want draw other type of controls within one control.

Example:
Display a Group box with a picture and a button as an item in TreeView

2nd Question:
My Control is Inherits Control class. How can I hide some properties and/or change its description.

Thank you for your time.
