    - Link error : debugging information corrupt First my usual comment - Visual C++ 6.0 is no longer supported. I strongly suspect that the problem you are running into is that if gdiplus.lib comes from the latest version of the PSDK then it was built with a much newer version of Visual C++. This newer compiler produces new forms of debug information that is not understood by Visual C++ 6.0 - hence the message about "corrupt" debug information. You need to either revert back to a (much ) older version of the PSDK or you need to update to a much more recent version of Visual C++. Tag: Visual C++ General sort of CListCtrl Visual C++

    - Interesting fast interop problem I'd be very careful in the assumption that the CLI generic containers and ArrayList are slow, as they should be regarded as quite optimized for their purpose. Writing your own native container, and using that in a C# application, will require quite a bit of support code. In addition, you should keep in mind that managed allocations are much faster than what you'd see with standard allocations done e.g. in stl containers, so you'd have to be prepared to write your own allocators (and not depend on frequent calls to new / delete). For containers, I just don't see any huge gain, and at least not anything justifying the amount of work it would be to get it to work. Optimizing certain algorithms through native libraries, however, can often be worth the work. As for the circular reference, I don't understand what exactly is preventing you from doing this. Are you talking C++/CLI, or C++ (meaning native) Please be specific, as they are two different languages. Tag: Visual C++ General sort of CListCtrl Visual C++

    - Combobox Hi, 1) Combobox: I'm working with VS 03, why I can't see " Properties" like here http://www.codeproject.com/combobox/combobox_tut.asp I want to add items for a combobox control but the "Data" is in gray color (disable). And I have to create CMyCombobox object to get the selected item What IDE ur using The sample is built for for VC6.0. 2) CListCtrl: How can I set Items like this: list.InsertItem(row, col, item); Actually row,col are not the terms usually used by CListCtrl.We have Item(just like first column in each row) and subitmes(other columns). Google is ultimate in providing u lots lots of samples for ur requirement. 3) Date format: How can I format this string: 02-02-2007 00:00:00 to: 02/03/2007 Let's do it with CString. CString str( "02-02-2007 00:00:00" ); int nPos = 0; str = str.Tokenize(_T( " " ),nPos); str.Replace(_T( "-" ),_T( "/" )); Are u done Thanx, ch.T.Gopi Kumar.

    - Allocation problem The problem might be that your program is modifying memory that it is not supposed to. Those problems can be difficult to find and are especially difficult to get help with from others that do not study your code extensively. Most people in these forums don't have time available to do that. You need to analyze your code and ensure that indexes and subscripts are never used with values that are out of range. Also ensure that other pointers are valid. Tag: Visual C++ General sort of CListCtrl Visual C++

    - Why no compilation error - Assigning int to std::string? There is an = operator overload that takes the string's element type as argument. In this case it would most likely be char - so it works fine. But there's no equivalent copy constructor. You could do something like this though :- std :: string tmp_Error1 (1, 65) This will make tmp_Error1 equal to "A". Tag: Visual C++ General sort of CListCtrl Visual C++

    - Asunchronous UI updating - other way? Some of operations on controls can be performed only by threads that created the controls. In case of multithreading you should apply approaches described in "How to: Make Thread-Safe Calls to Windows Forms Controls" article [ http://msdn2.microsoft.com/en-us/library/ms171728.aspx ]. Translated to C++ and Visual Studio 2005, you have to execute something like this. Instead of label->Text = "some text"; you have to add a delegate and a function: class Form1 { . . . delegate void SetTextDelegate(System:: String ^ s); void SetText(System:: String ^ s) { label->Text = s; } . . . }; Then, in your background thread, set the label’s text like this: array< System:: Object^ > params = { "some text" }; Invoke(gcnew SetTextDelegate(this, &Form1:: SetText), params); I hope this works.

    - The while loop and the CPU. The simple answer is: put a Sleep(1); in the loop. That would give you about a 1 millisecond response time. This works because the loop and the function call to Sleep(1) take under a microsecond and so your program is actually sleeping a 1000 time longer then it is processing. The better answer is probably use the blocking method like: Socket^ socket = tcpListener->AcceptSocket(); If you need to do other work at the same time you can just use more then one thread. One blocks while the other does whatever work you need done. The advantage of that is the AcceptSocket() thread can respond faster (as soon as the request comes in and get CPU time, which will happen right away if the worker thread is sleeping). On the other hand with an average response time of less then a milisecond the first method works fine for most cases and is easier to code. The worker thread can go at its own pace.

    - std::vector versus std::map performance The vector and map classes are obviously somewhat different, given that map is associative and yield logarithmic time lookups, and vector is a sequence which will yield constant time lookup -- granted a "key". The problem with replacing map with a magic number vector, is the amount of dummy items you will have to add to the sequence to achieve truly unique keys for the "real" items. There's likely to be quite extensive overhead in that scenario. I'd rather argue the use of a sorted vector on which you use binary searches to locate items a map and use of operator[] or map::find Both techniques will yield logarithmic time lookups, but a map will consume more memory per item than that of the vector. In addition, while the vector is consequtive, the map is a linked list. This means that the items in the map are likely to be spread across more than one memory page. This in turn means that lookups in a map will cause more page faults than lookups in a vector (the latter of which is likely to have all items in much fewer pages). The most apparent problem with the sorted vector is the sorting, and this will seriously cripple your performance if your application mixes insertions, deletions and reads to a greater extent. Generally, the vector approach will save you both time and memory if your application goes through a staged lifetime: 1. initialize the vector, 2. use the vector (lookup items), 3. clear the vector. What you should consider, though, is replacing map with stdext::hash_map (or any other third party STL'ish hash container), instead of the vector variation you mention. In essence your vector would be trying to assimilate a hashmap either way, so it's better to use something which does the job "out of the box", rather than to adapt an entirely different (and largely unfit) container.

Hi.

For example,

for(i=0; i<n; i++) {

...

XXX.InsertItem(0, A); // CListCtrl XXXClass::XXX

XXX.SetItemText(0, 1, B);

XXX.SetItemText(0, 2, C);

XXX.SetItemText(0, 3, D);

...

}

I could get the result of list, but it's reversed, i.e. last-in first-out.

I want like this:

A B C D

i=0

i=1

i=2

...

What's wrong

Sorry for this simple matter...

Re: Visual C++ General sort of CListCtrl

Prasad Somwanshi

for(i=0; i<n; i++) {

...

XXX.InsertItem(0, A); // CListCtrl XXXClass::XXX

You may like this to modify to,

for(i=0; i<n; i++) {

XXX.InsertItem(
LVIF_TEXT|LVIF_STATE, i, "A",
0, LVIS_SELECTED,
0, 0);
// Initialize the text of the subitems.
XXX.SetItemText(i, 1, "B");

XXX.SetItemText(i, 2, "C");

XXX.SetItemText(i, 3, "D");

You can follow same method there,too.
