Re: COleDateTime and comparisons

Before performing comparison, reset the hour/minute/second with a call to COleDateTime::SetTime.

i tried to do that and set the time to 1,1,1 and it always caused the date to become invalid (12/31/1899).. i am just combining the < > operators with my AreDatesEqual() function.. good enough for now.. just surprised there is not a date only control

You could subtract the two dates to get a COleDateTimeSpan and then use COleDateTimeSpan::GetDays() and check if it is 0;

File I/O inside a text file

I don't clearly understand your idea. If you want to get a Window's text, just use GetWindowText

Sorry for the newbie question, but lets say i have a text file, and in a certain location in the text file, there is a string of characters I would like to modify.. lets say its HIGHSPEED.. if I want to replace HIGHSPEED with DIALUP, without having excess whitespaces, how would I accomplish that? I want to remove the extra spaces that would be at the end if I were to seek the offset, and replace the word with my secondary word.

Thanks in advance.
btw. I can do this in MFC or C style. MFC prefered (bleh)

Is the file very large? If not, you could load it into memory, perform string replace and write back.

Even if it's so large, you can use String tech with FileMapping Roll eyes | :rolleyes:

it should be just:

m_MyListBox.AddString(myRecord.m_strField1);

you should post code if you want help with an error.. so we can see where the error is being caused.

When I run it, I get the messagebox error and when the dialog appears, I donot have the fileds loaded?
I have the code where I have tried to load the field..

void CMgen1View::OnInitialUpdate()
{
m_pSet = &GetDocument()->m_mgen1Set;
CRecordView::OnInitialUpdate();
LoadListbox(); //CALLING HERE
}

void CMgen1View::LoadListbox()
{

CMgen1Doc* pDoc = GetDocument();
CListBox* pLB = (CListBox*) GetDlgItem(IDC_LIST1);
CSectionSet sect(&pDoc->m_database);

sect.Open();

while(!sect.IsEOF()) {
pLB->AddString(sect.m_CourseID);
sect.MoveNext();
}
}

The database query you're executing has probably a misspelled column name. Check the SQL text.

how to setfocus "strongly"?

13-Aug-02 6:57

too few paramaters expected one.
I'm sure that your SQL command is incorrect;P

I want a user to definitely input a value into a certain editbox. If GetWindowText is "" I SetFocus back to it. But this doesnt prevent them from still ignoring it and pressing another button "Done" that proceeds with the rest of the code Needless to say the code crashes if you dont have an input in the editbox. Short of checking to see if the editbox is filled (and setting focus back to it if not)in the BN_CLICKED event of the "Done" button is there a way of forcing the user to make an entry in the editbox?

Thanks,
ns

disable everything else until the edit control is filled ?

I really should post my GUI helper class that makes it trivial to do this. Meanwhile, if you want to be really cool Cool | :cool:

do the following:

In the resource editor, set the OK button's "disabled" property.
Write a handler for the edit control's EN_CHANGE notification.
In the handler, get the edit control's text and enable the OK button only when the text is non-empty. Be sure to TrimRight() and TrimLeft() the text after you get it.

Okay. I'l give that a shot as well. I did a less sophisticated version without the EN_CHANGE, but thats a cool idea like you said.
