The operator<< of ostream will convert everything it takes to string, and then insert into the stream. So of course the value will be converted to string.
If you'd like to write as a integer but not a string, you may use the write() method.

it upto to you treat data in file... every thing written in file is string or binary digit (in case of binary file, which in turn also a string!)..

Please use the notification LVN_GETDISPINFO for implementing virtual list concept
for example see the link http://www.codeproject.com/listctrl/virtuallist.asp

Have you tried profiling to code to see why it's too slow?
I recommend looking at the DevPartner Profiler from here[^]

This type of control has already been suggested here, and probably more than once. He's not into research, though, but just wants someone else to do all of his work.

Hello,
i wondered, why you use this:
<br />
m_list.LockWindowUpdate();
nt nItem = m_list.InsertItem(x, pPlan->m_name);
m_list.SetItemText(x, 1, pPlan->m_den);<br />
pPlan->MoveNext(); <br />
x++;<br />
this maybe:
<br />
void CMyListCtrl::FillList()<br />
{<br />
<br />
CDatabase_Plan* pPlan = new CDatabase_Plan();<br />
if (!pPlan->Open())<br />
return;<br />
<br />
<br />
if (pPlan->IsOpen())<br />
{<br />
int x = 0;<br />
<br />
<br />
while (!pPlan->IsEOF() )<br />
{<br />
<br />
m_list.InsertItem(x, pPlan->m_name);<br />
m_list.SetItemText(x, 1, pPlan->m_den);
pPlan->MoveNext();<br />
<br />
x++;<br />
}<br />
}<br />
<br />
m_list.Invalidate();<br />
m_list.UpdateWindow();<br />
<br />
pPlan->Close();<br />
<br />
<br />
}<br />
<br />
this is an litle idea from me...hope this helps litle :)<br />
<br />
regards<br />

Hello,
if this is an CRecordset, try to use an open type like CRecordset::forwardOnly, means you want only to rad one more, from begin to end!
This brings you litle more speed, if you solve you problem please post here for me and others to now how!
regards
|
|
|
|
|
how to use forwardonly ?my CRecordSet is snapshot !!!!
Bravoone
|
|
|
|

again if it is the recordset and specialy the MoveNext part you could do the following:
make sure you don't collect record by record. Normaly a movenext requests only the next item from the server meaning just on record per fetch(data receivig)
you can retrieve multilple records in a single fetch.
Check the following Fetching Records in Bulk[^] for more details.

Its a suggestion if we suppose that you have 1000 records in your database and now you want to read their you can break their to 1000/5=200 and then create 5 thread in each thread you insert a loop for read of database in last thread on the loop you use from while (!pPlan->IsEOF() )i think its good than to use a loop for read 1000 records on runtime

hi i want to unregister the COM dll through code i had registered it through code and it works fine.

Load your DLL that you want to unregister, and call the "DllUnregisterServer" function of that DLL. Alternatively, you should be calling "DllRegisterServer" to register your COM dlls.

HINSTANCE hDLL = LoadLibrary("C:\\BhoNew.dll");<br />
if(hDLL == NULL)<br />
{<br />
AfxMessageBox("DLL can not be loaded..\r\nReason could ");<br />
}<br />
<br />
typedef HRESULT (CALLBACK *HCRET)(void);<br />
HCRET lpfnDllUnRegisterServer;<br />
lpfnDllUnRegisterServer = <br />
(HCRET)GetProcAddress(hDLL, "DllUnRegisterServer");<br />
if(lpfnDllUnRegisterServer == NULL)<br />
{
AfxMessageBox("DLL Entrypoint for function DLLUnRegisterServer could) ;<br />
}
but it gives the messabox above.
i had used this code to register it.
HINSTANCE hDLL = LoadLibrary("C:\\BhoNew.dll");<br />
if(hDLL == NULL)<br />
{<br />
AfxMessageBox("DLL can not be loaded..\r\nReason could ");<br />
}<br />
typedef HRESULT (CALLBACK *HCRET)(void);<br />
HCRET lpfnDllRegisterServer;<br />
lpfnDllRegisterServer = <br />
(HCRET)GetProcAddress(hDLL, "DllRegisterServer");<br />
if(lpfnDllRegisterServer == NULL)<br />
{<br />
AfxMessageBox("DLL Entrypoint for function DLLRegisterServer could not be found..");<br />
}
and it registeed that and worked but problem with unregistering,

this means that function is not present in your dll. Is it?

(HCRET)GetProcAddress(hDLL, "DllUnregisterServer");
if(lpfnDllUnRegisterServer == NULL)
{//shows this message.
i had tried this and worked fine,replaced the capital 'R' with 'r' and worked thanks for ur time.

The unregister functions name is this: DllUnregisterServer, with a lowercase R in unregister.
You typed it like this:
DllUnRegisterServer with a capital R.
Good luck
