Hi Matt,
Look what you write:
if (m_enable = true)
m_icon = ::LoadIcon (AfxGetInstanceHandle(),
MAKEINTRESOURCE(IDI_ON));
else if (m_enable = false)

but you need write: OMG | :OMG:

if (m_enable == true)
m_icon = ::LoadIcon (AfxGetInstanceHandle(),
MAKEINTRESOURCE(IDI_ON));
else if (m_enable == false)
etc.

dialog boxes and fonts

Gary Kirkham27-Jul-02 2:21

You design a dialog box in the resource editor with the system font set to small fonts, for example. When the user changes the system font to large fonts all of the dialogs are screwed up. Static text controls are no longer big enough to hold the text and things overlap, etc.

I have thought of different ways to handle this.

1. Place and size the controls for the large fonts and live with extra space when small fonts are selected.

2. Design two sets of dialogs, one for small fonts and one for large fonts...seems like a lot of work.

3. Programmatically move and resize the controls based on the selected font. Similarly, dont't use the resource editor and create everything dynamically

I was just wondering how everyone else handles this problem. I typically use the first method, but I don't like the results...

On a similar note...Have you ever noticed that NT/2000 uses a different shade of gray than 95/98? It is only noticable if you have a graphic displayed on a dialog that has a gray background designed to blend with the dialog color.

Why are nt and 98 different? How do you handle this? Do you have two sets of graphics in the resources, one for NT and one for 98? Is there another way to handle this?

Actually, since users can change the dialog box color to whatever they want whenever they want, both on NT/2k *and* '98, it's a bad idea to depend on any particular color working unless you actually force the dialog to paint using that color. A technique i've used is to either use a masked bitmap (or icon) to avoid drawing the background, or to remap colors in the bitmap once loaded (use with caution; may change colors you don't wish to change).

#1 is the way to go. #2 isn't a solution because there are more than just "small" and "large" fonts. You can set any font size up to 500% in the Display control panel. #3 is too much of a PITA, I only do it rarely when I have small, skinned dialogs and have to have the font a specific size. Otherwise, overriding the user's font selection is generally a rude thing to do.

Please be nice to persons who post in the incorrect forums as they probably do not have a vast posting history such as yourself.

The correct way to behave is to give them a good flaming in the first instance, so they will learn immediatly to correct there ways.

Also you will gain a lot of satisfaction flaming somebody who you are never likely to meet in person.

Well, if you already have your list control on your dialog, those are the steps: (I suppose that m_wndList is the CListCtrl

m_wndList.ModifyStyle(0, LVS_REPORT); //see CListCtrl::Create for other styles

<font color=green>//now have to add at least on column. We'll add 2 columns</font>
m_wndList.InsertColumn(0, "My name");
m_wndList.InsertColumn(1, "My phone");
<br>
<font color=green>//now we can add items, one after another.
//I use GetItemsCount to be sure that new items added at the end of list
//if you want to add at the beginning, just use 0 (zero) instead</font>
int nItem = m_wndList.InsertItem(m_wndList.GetItemsCount(), "Philip Patrick");
m_wndList.SetItem(nItem, 1, "111-111-222222");

That's all Smile | :)

How to replace last line of a file?

Jon Taylor26-Jul-02 22:14

Jon Taylor

26-Jul-02 22:14

I'm working on an app that dumps loads of trace information to a file, as XML:

<log>
<message>
....
</message>
</log>

Now, when the app closes I write "</log>" as the last line. However, the next time the app is run, I want to append to this file, which means I must remove that last line. (It's the XML "root node" Smile | :)

)

Now, I know I can rename the file, re-parse it and re-write it etc but these log files reach 10's of Mb in size, so it takes too long to do that.

So I want to over-write the last line with some new text instead. I seem to remember doing this using the C standard library in the dim and distant past, but can I do this using the C++ library?!! Mad | :mad:

I've tried with the <fstream> library, and seekp() & tellp() but am getting a bit unstuck Unsure | :~

Any ideas anyone?

Re: How to replace last line of a file?

Nish Nishant26-Jul-02 22:40

Open the file using CreateFile. Now use SetFilePointer with the FILE_END flag. Now call SetFilePointer with FILE_CURRENT and use -8 as the lDistanceToMove value. Thus it moves back 8 bytes (</log>\r\n). If you have only a \n, then put -7 as lDistanceToMove. Now write your stuff and close the file.

i think a slightly more robust way would be to read the last 100 bytes into memory and find the string and calc its offset and use that when seeking the file position ... unicode chars and whatnots might screw u up if u hard code the sizes into the algorithm

hi,

If you're keen on using the C++ library, u could do this with fstream's ::seekg to seek to the end(ios::end) minus the offset which is calculated. The offset would be calculated using sizeof(string). Specify the offset in (-)ve. Now you can write the present contents from this location.

P.S. Open the file in binary mode.

hope this helps,
Sharad

cmb1 (and edt1) and OFN_EXPLORER

Atlantys26-Jul-02 21:08

26-Jul-02 21:08

So I've got this nifty CFileDialog-extended class that doesn't use the OFN_EXPLORER flag. I need to check the extension the user selected, so to do that, I look at the "cmb1" control (well, also some other Explorer-style control identifiers)

So everything was going well and good, until I found an article on how to allow CFileDialog-derived classes to use the OFN_EXPLORER flag (basically make the OPENFILENAME size 12bytes larger). And now the ASSERT fails. Cry | :((

CWnd* pComboBox = GetParent()->GetDlgItem(cmb1);
ASSERT_VALID(pComboBox);

So, if anyone can point me in the right direction, or just outright solve this problem, that would be great! (I'd rather not have to use Win32 to solve this though)
Thanks in advance.

GDI Rotation Question

26-Jul-02 20:23

Hello all,

I am writing a little vector animation program and want to add rotation to my basic shapes. I have an algorithm that works ok... other than the fact that is shrinks the shape as it rotates! It works much better in OpenGL since its points are floating point. As far as I can tell, the shrinking is due to round off error, going from double to int. I am using the GDI in this case so I can't really do much about it. I am also programming this to run on both 9X and XP so no world transformations. I intend to make this method work for all gdi type basic shapes it is only working (appropriately) with the shapes that are invariant under rotation, the Polyxxxx shapes.

So, can anyone verify my diagnosis or point out other problems? Moreover, can anyone suggest a... less destructive way to rotate?

Thanks alot
////////////////////////////////////////////////////////////////////
int CShape::Rotate(int nAngle) // thar she be!
{
double dAngle = -nAngle * DEG_TO_RAD,
tX, tY, tX2, tY2;

for(int i = 0; i < m_aSourcePoints.GetSize(); i++)
{
tX = m_aPoints[i].x - m_ptRotate.x;
tY = m_aPoints[i].y - m_ptRotate.y;

tX2 = (int)((tX*cos(dAngle))-(tY*sin(dAngle)))+m_ptRotate.x;
tY2 = (int)((tX*sin(dAngle))+(tY*cos(dAngle)))+m_ptRotate.y;

//round the rotates point values
if((tX2 - floor(tX2)) >= 0.5) tX2 = ceil(tX2);
else tX2 = floor(tX2);
if((tY2 - floor(tY2)) >= 0.5) tY2 = ceil(tY2);
else tY2 = floor(tY2);
