You need an interpreter of commands, I made a interpreter for FTP a couple of years ago, it's the only solution...

What fun! I designed and programmed ATE to test microcircuits, functional and in-circuit, and a cute little HP9825 desktop calculator ran the whole thing. You typed code into it's 64K memory, then saved the program on an 8" floppy disk. It's native language was hpl, which quickly expired because nobody liked a funny looking language (it used lower case). I liked it because one of the storable functions was the <Store> key. Once stored, the characters were treated as a command. That let me write programs that modified their behavior to adapt to the environment (and I mean physical - EMI, temp, etc.) and increase the accuracy of measurements on the circuit. It drove the QC people nuts to have programs around that kept changing themselves
Let's bring back hpl!!!!

You have to embed an interpreter in your program. There are plenty out there that are free and can be integrated into a C++ program.

Hello -
I'm having some novice problems with using the Replace() method of CImageList. The Add() method allows for a COLORREF to be used for the mask color, but Replace makes you supply a CBitmap for the mask.
Does the bitmap mask need to be custom generated for each bitmap that I want to insert (via Replace) into the imagelist? All of my images have a standard background color (RGB(192,192,192)), so it would be great if I could do:
m_imagelist->Replace(iOld, pNewBitMap, RGB(192,192,192));
My images are loaded into the imagelist at runtime. Other than the background color and size, I don't have any compile-time knowledge of their content.
Currently, I'm doing something like this:
void CSomeView::OnInitialUpdate()
{
...
m_imagelist.Create(16, 16, ILC_MASK | ILC_COLOR8, 0, 0);
m_imagelist.SetImageCount(20);
...
GetTreeCtrl().SetImageList(&m_imagelist, TVSIL_NORMAL);
...
}
void CSomeView::OnSomeEvent(...)
{
// IDB_MASK is a 16x16 monochrome bitmap
// that's all RGB(192,192,192)
CBitmap *pbmpMask = new CBitmap();
pbmpMask->LoadBitmap(IDB_MASK);
// load some bitmap from a file
hBitmap = (HBITMAP)::LoadImage(NULL,
strPathToTheFiles + "SomeFile.bmp",
IMAGE_BITMAP, 16, 16,
LR_LOADFROMFILE | LR_CREATEDIBSECTION | LR_DEFAULTSIZE);
CBitMap *pBM = new CBitmap();
pBM->Attach(hBitmap);
m_imagelist.Replace(iSomeIndex, pBM, pbmpMask);
GetTreeCtrl().Invalidate();
}
I've tried several other approaches, but nothing gives me the transparent background. So... Do I need to build a bitmap mask for each bitmap using ::BitBlt and friends?
Thanks,
David Emery

Did you change back the Imagelist in the Tree control, like you did
in your OnInitialUpdate()?
I am not sure if just Invalidate() the tree control really fix your problem.
Did I really catch your problem?

Yes, I do a SetImageList after the Replace(s). Sorry, I somehow left that out of the code snippet that I posted. The snip should be something like this:
void CSomeView::OnSomeEvent(...)
{
...
m_imagelist.Replace(iSomeIndex, pBM, pbmpMask);
GetTreeCtrl().SetImageList(m_pImageList, TVSIL_NORMAL);
GetTreeCtrl().Invalidate();
}
I'm messing with some code right now that generates a mask from the image that is being inserted into the imagelist. I'm having a little taste of success, but darn I wish that Replace() just would let me send a COLORREF instead of a CBitmap mask.
My mask generation looks like this. It works for the first image, but not subsequent, so still having some problems. Do you see my error(s)?
void CSomeView::OnSomeEvent(...)
{
...
CBitmap *pMask = GetMask(pBM);
m_imagelist.Replace(iSomeIndex, pBM, pMask);
GetTreeCtrl().SetImageList(m_pImageList, TVSIL_NORMAL);
GetTreeCtrl().Invalidate();
}
CBitmap *CSomeView::GetMask(CBitmap *pImage)
{
HBITMAP hbmMask = NULL;
BITMAP bm;
// get bitmap size info
pImage->GetBitmap(&bm);
// Create memory DCs to work with.
HDC hdcMask = ::CreateCompatibleDC(NULL);
HDC hdcImage = ::CreateCompatibleDC(NULL);
// Create a monochrome bitmap for the mask.
hbmMask = ::CreateBitmap(bm.bmWidth, bm.bmHeight,
1, 1, NULL);
// Select the mono bitmap into its DC.
HBITMAP hbmOldMask = (HBITMAP)::SelectObject(hdcMask,
(HBITMAP)hbmMask);
// Select the image bitmap into its DC.
HBITMAP hbmOldImage = (HBITMAP)::SelectObject(hdcImage,
pImage->m_hObject);
// Set the transparency color to be the top-left pixel.
// ::SetBkColor(hdcImage, ::GetPixel(hdcImage, 0, 0));
// force transparency color
::SetBkColor(hdcImage, RGB(192,192,192));
// Make the mask.
::BitBlt(hdcMask, 0, 0, bm.bmWidth, bm.bmHeight,
hdcImage, 0, 0, SRCCOPY);
// Tidy up.
::SelectObject(hdcMask, hbmOldMask);
::SelectObject(hdcImage, hbmOldImage);
::DeleteDC(hdcMask);
::DeleteDC(hdcImage);
CBitmap *pBM = new CBitmap();
pBM->Attach(hbmMask);
return pBM;
}
Thanks for your reply.

I wish that I understand what you are trying to accomplish.
1)If you plan to replace the bitmap, why you are not using the
State bitmap instead. GetTreeCtrl().SetImageList(m_pImageList, TVSIL_STATE);.
I don't feel that you use the mask for anything else than changing
the background color of your bitmap.
2)I didn't see any apparent problem with your mask method but I question if you really
need to create a mask since you plan to change the entire bitmap index.

>> I wish that I understand what you are trying to accomplish.
I can't really describe the app's usage other than it's a tool for the battlefield.
The application receives CORBA messages that contains an index number and a filename. I need to read the file, convert it to a bitmap (the file can be a bmp, jpg, or gif), and store it into an imagelist using the index number. I receive a bunch of these messages at startup and then any number of messages throughout the app's lifetime. I have no control over when or why these messages will come. Sometimes the new image is a thumbnail of some dynamic situation.
I also then receive updates to items that reference the imagelist. These updates may include changes to the image index number. These items are blobs on a map, tree nodes, tabs, toolbar buttons, menu items, etc.
>> why you are not using the State bitmap instead.
That would only help if my item was selected or not. I need to dynamically update any and all images.
>> I don't feel that you use the mask for anything else than changing the background color of your bitmap.
When I started this, I guess I didn't understand masks. I thought that I just needed to specify a transparency color. What it seems is that there is a one-to-one mask image for every bitmap image in the image list. When you do an imagelist->Add(pImage, COLORREF), the imagelist generates your mask image for you. When you do a imagelist->Replace(pImage, pMask), you must manually create the mask yourself.
>> I question if you really need to create a mask since you plan to change the entire bitmap index.
I didn't think that I needed to create a mask either. I searched everywhere to try and find some example code of the Replace method.
The GetMask code that I posted yesterday does work. For every image that I Replace(), I must create a unique mask.
Thanks for your time and help.

I can only give you ideas that could work in your case since I did
similar things with a ListView.
1. In my case, I didn't create a mask so when I call Create() for the ImageList, the
crMask was set to CLR_NONE (0) but I guess in your case you should probably use RGB(192,192,192).
2. I also use the default color: ILC_COLOR (0) not ILC_COLOR8 but I understand why you are using it.
3. AFAIK Replace function works but you can always use:
BOOL GetImageInfo( int nImage, IMAGEINFO* pImageInfo)
to change the image list directly, don't forget to delete previous bitmap if you plan to use it.
4. You may want to take a look at these ImageList macros:
ImageList_Create, ImageList_LoadImage, ImageList_AddMasked, etc
Thank you and good luck

Ok..mm... where do i start.
I downloaded the skinstyle source and example app from the codeproject (controls>dialogs and windows>advanced UI and skins). I compiled the example and it worked fine. I wanted to export the project to another compiler (the mingw, Dev-C++ IDE, www.bloodshed.net) because this seems to make the final executables smaller, i also dont know why: if you write a simple app which shows a window it is about 5kb in mingw and 24kb in Visual C++. Anyways, i copied the code exactly as in the visual c++ project of the skinstyle example but then i get linker errors like:
main.cpp: undefined reference to `SkinDialog::LoadSkin(char *)'
I had these errors before in other apps and i believe they are caused by a missing object file (.lib, .a) right? I included the .lib file from the skinstyle project in my app and the other necessary lib files but it still gives me those errors. Anyone know why? Does anyone know how to compile the project under mingw?

I have created a print preview window using a CRichEditCtrl. Every thing is working great. I know where the start and end of my pages and where my page headers and footers are. But can someone help me with How to draw a line in the control. I have tried getting the CDC of the control and using drawline but that does not seem to work either.
thank you.

Hi,
I've been chasing a solution to this in newsgroups etc. for the best part of a year without a single response. Using VC++ 6 SP5 on Win89. VS won't allow add-ins to start and reports that each add-in's server object couldn't be started. One or two did work for a while but none do now. Any ideas?

Hello Gary,
Do you have Visual C++ 5.0 installed on your machine ? If so, make sure that all add-ins (with the same version) are installed for both VC++ 6.0 and VC++ 5.0.
A few weeks ago, I had the same problem. One of my add-ins was a newer version and I got it installed for my Visual C++ 6.0. It won't start up. I then installed the same version for my VC++ 5.0. Things worked.
Best of luck, Gary,
Bio.

My boss likes data displayed in disabled edit boxes (ugh!), however recentily I have been badgered to adapt the edit box so that if, the amount of text in the box necessiates a Scroll Bar being displayed, one will automatically appear, otherwise if there is not enough text to necessiate a scrollbar, none is shown.
Is there any easy way of achieving this.
Regards
Ray

One thing you may want to try is to change the style of your control to
Read Only. The control may still get the focus so the user can view all
data by using the arrow keys. By disabling a window, the scrollbar too is
disabled.

Hi,
I created an SDI Application.I want remove the Toolbar and Menu from my Application. For that I created a Class from CFrameWnd and attached it to the DocumentTemplate and Changed the dafault menu item as NULL.I am getting the output window with a lot of assertion failure.What all steps I need to follow to remove the ToolBar and Menu from the Application.
Help please.

*IF* you are using VC6,
Removing Menu:
BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
cs.hMenu = NULL;
return CFrameWnd::PreCreateWindow(cs);
}
I belive previous version of MFC were getting p*ssed if you try this...
So old aproach was create window with menu. Create own message WM_APP+100, post this message from OnCreate, and when you get this message
do something like this:
HMENU h = GetMenu();
SetMenu(NULL);
DestroyMenu(h);
Toolbar is easy, change on create to look something like this:
int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CFrameWnd::OnCreate(lpCreateStruct) == -1)
return -1;
return 0;
}

The toolbar you can remove when you are creating your SDI application, you'll find an option, to create or not to create the tool bar there.
To remove menu, you have to override CFrameWnd::LoadFrame() of your Frame window and place a code inside it, like this:
BOOL CMainFrame::LoadFrame(UINT nIDResource, DWORD dwDefaultStyle, CWnd* pParentWnd, CCreateContext* pContext)
{
BOOL bRetVal = CFrameWnd::LoadFrame(nIDResource, dwDefaultStyle, pParentWnd, pContext);
if(bRetVal){
GetMenu()->DestroyMenu();
SetMenu(NULL);
}
return bRetVal;
}

I'm working on a small program with two list controls declared as
<br />
CListCtrl List1, List2;<br />
These are public member variables of CListTestDlg.
The effect I want is for the contents of List2 to change depending on which row was clicked in List1. I have created a handler for the WM_NOTIFY message to handle the NM_CLICK message.
<br />
BOOL CListTestDlg::OnNotify(WPARAM wParam, LPARAM lParam, LRESULT* pResult) <br />
{<br />
LV_DISPINFO* lvDispInfo = (LV_DISPINFO*) lParam;<br />
CEdit* pEdit;<br />
<br />
switch (lvDispInfo->hdr.code)<br />
{<br />
case LVN_BEGINLABELEDIT:
pEdit = List1.GetEditControl();<br />
break;<br />
case LVN_ENDLABELEDIT:<br />
if ((lvDispInfo->item.pszText != NULL) && (lvDispInfo->item.iItem != -1))<br />
{<br />
List1.SetItemText(lvDispInfo->item.iItem, 0, lvDispInfo->item.pszText);<br />
}<br />
break;<br />
case NM_CLICK:<br />
char text[11];<br />
int i;<br />
<br />
while ((List2.GetItemCount() > 0) && (lvDispInfo->item.iItem != -1))<br />
List2.DeleteItem(0);<br />
List1.GetItemText(lvDispInfo->item.iItem, 2, text, 10);<br />
i = atoi(text);<br />
while (i-- > 0)<br />
{<br />
List1.GetItemText(lvDispInfo->item.iItem, 0, text, 10);<br />
List2.InsertItem(lvDispInfo->item.iItem, text);<br />
}<br />
break;<br />
}<br />
}<br />
The problem I have is that for the NM_CLICK part of the switch statement, lvDispInfo->item.iItem is always zero, regardless of which row is clicked on. However, if I use lvDispInfo->item.mask instead of lvDispInfo->item.iItem things work as I would like.
lvDispInfo->item.iItem appears to be set correctly when dealing with LVN_BEGINLABELEDIT and LVN_ENDLABELEDIT parts are processed.
Please tell me what am I missing?

Are you programming for WinCE?
If not, so here is your problem. The structure LV_DISPINFO is defined and working ONLY in WinCE. In Win32 you have to cast your lParam to LPNMITEMACTIVATE and you will get the item index in iItem member of this struct. Or -1 if no item was selected

I had tried NMLVDISPINFO, but that gave the same results as LV_DISPINFO, couldn't see LPNMITEMACTIVATE on MSDN, but it does what I want.
