Dynamic ComboBox

[Jiko]

We have a map with files that we want to be shown in a combobox. The number of files in the map varies. When we chose a file from the combobox, that filename should be saved as a CString. We use this CString when we send the file on a comport.

I don't know about others but what do you mean by a map? Do you mean a map as in how to get from A to B?

I also don't quite follow what you are trying to achieve here.

Hi,

Do you mean that you want the contents of a directory displayed as items in a combobox?

Yes, that's what I mean.

Well if you are using the CListBox Object you can use the Dir method of it to populate the list. Then use the MyList.GetText (MyList.GetCurSel(), myString ) to return the selected filename in your CString object.

We solved it like this.
This part put the names in the file LK-lista.txt in the combobox.

BOOL CST7kommDlg::OnInitDialog()
CString Filnamn = "C:\\Mina dokument\\Laddningskurvor\\LK-lista.txt";
CStdioFile file;
BOOL fSuccess = file.Open(
_T(Filnamn),
CFile::modeRead |
CFile::shareDenyRead |
CFile::typeText
);

CString strOutput;
while(file.ReadString(strOutput))
m_xCombo.AddString(strOutput);


This part opens the file chosed in the combobox.
char fil2[10];
int h=m_xCombo.GetCurSel();
if (h == CB_ERR){
strcpy(errstring,"Välj en laddningskurva."
MessageBox(errstring);
}
else{
m_xCombo.GetLBText(h,fil2);
UpdateData(FALSE);
CString filnamn = "C:\\Minadokument\\Laddningskurvor\\";
Filnamn +=fil2;
Filnamn += ".txt";
CStdioFile file;
fSuccess = file.Open(
_T(Filnamn), CFile::modeRead | CFile::shareDenyRead |
CFile::typeText
);
