Hey Ppl,
I have 6 classes derived from CASyncSocket namely CMySocket1,2...6
Each of these MySocket class has its own OnReceive() function.
Sockets are used for TCP/IP connection and there are 6 'Connect' buttons on the front-end. Application is an SDI app. using CRecordview class.
Now what if more than one OnReceive() events get triggered at the same time?
There would be a case of data gone missing, isnt it? Alternatively how can i put these sockets in different threads so that they become independent of each other??

Hello everyone,
I asked a related question about when DllRegisterServer is called and my question is answered. Now I am thinking that when DllUnregisterServer will be called?
It is reasonable to understand that during installation process or when we set Register Output to Yes in Visual Studio 2005, during build process of Visual Studio 2005 regsvr32.exe will invoke DllRegisterServer to put the related registration entries to Windows Registry.
But when (what operation) will trigger DllUnregisterServer be invoked in Visual Studio 2005?
thanks in advance,
George

A command like "regsvr32.exe /u test.ocx" will invoke the DllUnregisterServer() function in the dll/ocx. But i didnt understand what you mean by "But when (what operation) will trigger DllUnregisterServer be invoked in Visual Studio 2005?".
you mean In your system visual studio is calling DllUnregisterServer() of some dll?

Thanks nave,
Sorry that maybe I have not made myself understood. My question is not regsvr32 will trigger DllUnregisterServer, but how and when Visual Studio 2005 will trigger regsvr32 (or DllUnregisterServer).
Because I think Visual Studio 2005 could use Register Output option to trigger regsvr32, and then finally trigger DllRegisterServer, and Visual Studio 2005 must have some methods to trigger DllUnregisterServer as well.
Any comments?
regards,
George

If you check the project settings of an ocx or com dll, you can see the settings like "regsvr32 /s $(OutDir)\$(ProjectName).dll" in the Post-build events. But i dont think some thing like "regsvr32 /s /u $(OutDir)\$(ProjectName).dll" comes in the project settings of any project.

Hi nave,
I have checked that it is empty for me. I am using Visual Studio 2005, are there any other configurations in IDE which affects DllUnregisterServer?

Are you saying that your applications DllUnregisterServer() function is called from visual studio?

Hi nave,
My original question is about how Visual Studio 2005 invokes DllUnregisterServer, like from what configuration or something.
I have checked that in "Custom Build Step", it is empty for me. I think there should be somewhere else in Visual Studio 2005 which triggers invocation of DllUnregisterServer.

George

that command will be there in the post buikd event only if your project is a com dll or ocx

Thanks nave,
Do you mean as default, the command will be in post build event when we create a DLL project in Visual Studio 2005? I have checked that in my environment it is not as default and the post build event is empty.

If that string is not specified in the post build event, your com dll will not be registered automatically after building the project.

Thanks nave,

if VS have to call the Register/UnRegister of a dll, that should be written in the post build events. If it is not there, Register/UnRegister will not be called.

Thanks nave,
For registration, beyond the customer build events, we could also use Register Output option to trigger Register of a DLL;
For unregistration, I think in your points, there are no other option to trigger Unregister beyond customer build events, right?

When you use unregister the server,
regsvr32 /u a.dll

Actually yes! Most western languages do not require Unicode, it was the rest of the world it was mainly designed for. Just enclose C-style string with ‘_T()’ (like ‘_T(“some string”) ). If you are using MFC, which using CString implies, then most of your work is done for you.

Ok .. I have a CListCtrl for which I've implemented sorting functionality. With this I am also showing an up/down arrow in the header control. Now, for one of the headers, the max length for the content is 2 digits. Now after sorting, with the arrow appearing in the header my header width becomes larger than the contents. After sorting has finished, I tried to the set the column width using
SetColumnWidth(selColumn, LVSCW_AUTOSIZE); OR
SetColumnWidth(selColumn, LVSCW_AUTOSIZE_USEHEADER..);
But it auto-sizes the width to 2, which is the length of the contents and this way I cannot see the complete header!
I am wondering if there is a way to auto size the width according to header's width ...
any help is appreciated...
Thanks..

EDIT: if my answer has nothing to do with what you asked for... please tell me and I will delete it.
I am not as good as other users but I try to explain my point of view.
I have used a CListCtrl in my project with a variable number of columns, the width of some columns are fixed the other are variable depending on the length of the subitems.
To do this, I have made a bypass (maybe there are better ways to do it, but it works for me).
I explain a bit to let you understand my way of thinking. My project is to do Fuzzy control, that means some inputs go through a regler to give a concrete value to an output. The CListCtrl is used in the regler to stablish the different combinations that rule the output's value. So it needs to know how many inputs are connected to the regler (output is only one) to set the number of columns. Every input has attributes that are used to stablish a rule (like "when I11 and I21 and I35 then O21 with X=0,75", Input1 parameter1 and Input2 parameter1 and input3 parameter5 should trigger output2 parameter1 with a value in 75%)
I hope you get the idea. It is important to my structure.
I have coded the initialization of the CListCtrl and the Upgrade of values in different functions that are called when necessary by the OnDraw (). This is because if the name of any attribute changes, or an input connection is deleted or something like this, I close the form because the complete structure of the ListCtrl should change as well.
I do it more or less like that:
void CParamRegTabView::InitializeView()
{
LV_COLUMN lvCol;
int nCol = 0;
DWORD dwStyle;
dwStyle = LVS_EX_FULLROWSELECT | LVS_EX_GRIDLINES;
m_clcRuleList.SetExtendedStyle (dwStyle);
lvCol.mask = LVCF_FMT | LVCF_SUBITEM | LVCF_TEXT | LVCF_WIDTH;
lvCol.fmt = LVCFMT_CENTER;
lvCol.cx = TABCOLWIDTH - 35;
lvCol.iSubItem = 0;
lvCol.pszText = "RegelNr.";
m_clcRuleList.DeleteColumn (nCol);
m_clcRuleList.InsertColumn (nCol, &lvCol);
for (nCol = 1; nCol <= m_pRegPar->m_cmlInConSet.GetCount (); nCol++)
{
lvCol.cx = nMaxLength * 8;
lvCol.iSubItem = nCol;
lvCol.pszText = TransformTextFormat(m_pRegPar->m_cmlInConSet[nCol-1]);
m_clcRuleList.DeleteColumn (nCol);
m_clcRuleList.InsertColumn (nCol, &lvCol);
}
lvCol.cx = TABCOLWIDTH - 40;
lvCol.iSubItem = nCol;
lvCol.pszText = "Oper.";
m_clcRuleList.DeleteColumn (nCol);
m_clcRuleList.InsertColumn (nCol, &lvCol);
lvCol.iSubItem = nCol+1;
lvCol.pszText = "GWF";
m_clcRuleList.DeleteColumn (nCol+1);
m_clcRuleList.InsertColumn (nCol+1, &lvCol);
lvCol.cx = nMaxLength * 8;
lvCol.iSubItem = nCol+2;
lvCol.pszText = TransformTextFormat(m_pOutCon->m_szOutName);
m_clcRuleList.DeleteColumn (nCol+2);
m_clcRuleList.InsertColumn (nCol+2, &lvCol);
lvCol.cx = TABCOLWIDTH - 38;
lvCol.iSubItem = nCol+3;
lvCol.pszText = "AttValue";
m_clcRuleList.DeleteColumn (nCol+3);
m_clcRuleList.InsertColumn (nCol+3, &lvCol);
m_bJustOpened = FALSE;
return;
}
code above stablish the ListCtrl formats, columns headers, width...
the insertion of the values, attribute names and so on... (contents of every cell) are made in DrawViewElements (), but this has nothing to do with your question.
and I call them by...
void CParamRegTabView::OnDraw(CDC* pDC)
{
if (m_bJustOpened)
InitializeView ();
if (m_bListRedraw)
DrawViewElements ();
return;
}
So... with this code. When a critical change happens (attribute deleted, input disconnection or something like that) I close the frame and by new opening the table is new configured thanks the m_bJustOpened (set to TRUE in the constructor). When a working point of any input changes its value, I set the m_bListRedraw to true and send a pDoc->UpdateAllViews (NULL) from the origin of the value change.
The only problem I could not avoid yet is that, when a double clik in the separator between two columns headers is made, then the column is resized to the header content size, cutting the contents of the subitems in that column.
If anyone knows how to avoid it, the answer will be wellcome, but atm is not important for me.
I mean:
Header =___________________________|____Input1____|
anywhere in the column a subitem with = |VeryFastChange|
after double click in the right "|"
Header =___________________________|_Input1_|
anywhere in the column a subitem with = |VeryFa..|
(The underscores are empty spaces, but if not used, the perspective is lost, multiple empty spaces are not considered)
Sorry for the length, I hope it helps you.
Any other tips from people that reads it are wellcome

Readjust the column's width after each item is added.
