How to increase font size for a specific button? I tried to change the nHeight but it doesn't seems to change the font size.
Code:
CFont font;
font.CreateFont(
12, // nHeight
0, // nWidth
0, // nEscapement
0, // nOrientation
FW_REGULAR, // nWeight
[Code] ....
Change the frame window size according to font size increases.
View 3 Replies View RelatedI need use GetTextExtent and I don't understant why GetTextExtent always return the same value if I change some values of the selected font. This is my example:
Code:
LOGFONT lf;
pOldFont->GetLogFont(&lf);
CString sExampleSizeByChar;
sExampleSizeByChar = _T("hello");
DWORD dwPixelsByChar = dc.GetTextExtent(sExampleSizeByChar).cx / 1.15;

Why I get always the value 24 when I call GetTextExtent if I change the font size?
Can change the menu bar font size in CMainFrame::OnCreate()? Here's what I have:
Code:
int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct) {
CRect rect;
GetClientRect(&rect);
if (CFrameWnd::OnCreate(lpCreateStruct) == -1) {
return -1;

The line "m_wndToolBar.SetFont(&m_font);" does nothing.
I recently switched from Visual C++ 6.0 to Visual C++ 2008.
With Visual C++ 6.0, I used a callback method to get available font styles for a given font. I don't think that is working correctly anymore.
What is the best approach for determining which font styles (e.g., bold, italic, etc.) are available for a given font. I am not using .Net.
Actually whats the size of the stack and we can increase the size?

View 1 Replies View RelatedI was working with a richTextBox on setting its font, color and size. I found examples and got that to work. It seems like a kludge to me just to get the size set.
So, now I need to do the same for a listBox. I got the font and color set but cannot get the font size set.
The error I am getting is on line 6 below: listBoxTopLevelChecklist.Font.Size = fontDialog.Font.Size;
VS 2013 Express tells me this property (font.size) is read-only. That was the same error I got on the richTextBox until I found way using the .SelectionFont structure, but the listBox doesn't support that. So, I'm stuck.
Line 8 on is working finr for the richEditBox.
DialogResult result = fontDialog.ShowDialog();
if (result == DialogResult.OK) {
listBoxTopLevelChecklist.Font = fontDialog.Font;
listBoxTopLevelChecklist.ForeColor = fontDialog.Color;
listBoxTopLevelChecklist.Font.Size = fontDialog.Font.Size;

That code should make the size of the pointer (how many chars it can store) bigger but when i run it it show always 3 char positions while it should show N*M.
Code:
#include <stdio.h>#include <stdlib.h>
int main(void) {
int M, N, P, i;
scanf ("%d %d", &M, &N);
P = M * N;
char *c = malloc(P * sizeof(char));

View 1 Replies View RelatedI made my own custom message/dialog box.
I have a template mock up view using xaml. I have a viewmodel that raises the message property. I binded the message property to a textblock inside my xaml.
Since my messages are different for every viewmodel I have.
E.g.in every viewmodel, I have something like
messagewindow.Message = "This is a new message";
dialogService.ShowDialog(Success, messageWindow);
In one of my messages, I want to make the font bold and different color for a specific message segment.
How can I do that without messing up with the other messages that inherit from the xaml or code behind?
Currently, I'm not using any code behind and a lot of the examples online I've seen use code behind and/or don't have dynamic message textboxes.
I'm a little lost with this program. The idea is to dynamically allocate an array and increase its size every time a new integer is inputted by the user. I believe it is a memory leak but as we have just started learning this I'm not sure how to recognise it. Sometimes I can input as many integers as I want other times 2 or 3 before it crashes. When I can input enough values i exit the loop and send it to the sort function and mean calculator function, all works fine there except the last number inputted becomes this huge value not hexadecimal though... As such I'm at a loss as what to look at next, so here you go:
#include <iostream>
using namespace std;
void SelectSort(int [], int);
float MeanCalc(int [], int);
float MedianCalc(int* [], int);

Is there an easy way to create a column of buttons ina listView?
I need that every file of the listView has a button in the first cell. Is that possible?
I have multiple bitmap buttons of non-square shape. Because of their odd shape I can overlap them and they will still look good on screen, which is what I want - that certain layout.
The problem is that because underlying button in reality is square (which I am subclassing), the bitmap of one button may overlay with the non-bitmap area of the other button (in the underlying square). This means that 2nd bitmap button will not receive notification because the press is registered with top level window only.
Is there a way that both windows can receive the notification and check if they are in the hot spot, they will respond? I know this is against windows design.
I have successfully compiled a code where I created an array of buttons. I have added a click event to it like this :
Code:
buttons[indexofhashis2]->Click += gcnew System::EventHandler(this, &Execute::GOBUT_Click);
I have a standard event like this
Code:
private: System::Void GOBUT_Click(System::Object^ sender, System::EventArgs^ e) {
int x;
x = sender->Location.X;
}
Returns error saying Location is not a member of Object^.
I'm trying to create an array of button (user/runtime created buttons) and get different interpretations of the click event depending of wich button is clicked.
For example, if we create buttons[0] I wish to get the 0 or something relevant into the GOBUT_Click event.

my problem:I have a text (singleline) and a fix width for the whole text.
How do I find the correct font (height) for this text?
I want create menu button to change font of CString displyed in main window. We can see string "SAMPLE",and when i press menu button that i created i want to string "SAMPLE" to display with different font,i already created CFont object and added italic style with CreateFont;
This is my menu function:and CString m_text and CFont font1 are declared in FesbDoc.h
ON_COMMAND(ID_EDIT_FONT, &CFesbView::OnEditFont)
void CFesbView::OnEditFont() {
CFesbDoc* pDoc = GetDocument();

I needed to change Default Text attributes (font and color) . So I wrote following code , UnicodeTextOut function. I called this function once in each 55ms to update the display screen. but I observed that my Screen used to become grey like a crash after sometime . If I use Minimize an Maximize window , the screen was restoring back for some time.
When I thought over the code , I got my mistake that CreateFont initialization should be done once in the program and probably outside the function.
void UnicodeTextOut(int x, int y, CString s, UINT justify,int GreyScaleFlag) {
HFONT hFontUnicode;
HFONT hfOld ;
hFontUnicode = CreateFont(16, 0, 0, 0, 0 , 0, 0, 0, 0, 0, 0, 0, 0, _T("Aerial"));
[Code] ....
Then I shifted the line hFontUnicode = CreateFont(16, 0, 0, 0, 0 , 0, 0, 0, 0, 0, 0, 0, 0, _T("Aerial")); in my screen class constructor and made hFontUnicode global .
This solved my problem as expected. Why a system crash after certain no of CreateFont calls ?
I am trying to draw a shape or font on dialog and then fill the outline. I have 2 buttons on this 2 buttons I have the following code
Code:
case IDC_BUTTON1:
MessageBox(hDlg, L"Start Drawing!!", L"ButtonPressed", MB_OK | MB_ICONEXCLAMATION);
hDC = GetDC(hDlg);
brush = CreateSolidBrush(RGB(128, 128, 128));
SelectObject(hDC, brush);
[code].....
When I remove the BeginPath() and EndPath() functions my lines are being drawn. But when I insert this BeginPath() and EndPath() and StrokeAndFillPath(hDC); the nothing is being drawn.
Why it is not doing as per the expectations. I want to draw a shape for example A with a outline. And i want it to be closed when drawing is ended and filled the hollow portion.
What am I doing wrong in this ?I am not implementing it in WM_PAINT but drawing is done in WM_LBUTTONUP.
I must take an old MFC project in VC++ 6.0 and make changes.
The problem is text size in screen is different from size in print preview.
for example with this font
Code:
CFont f50;
f50.CreateFont(100,0,0,0,FW_BOLD,0,0,0,DEFAULT_CHARSET,OUT_DEFAULT_PRECIS,
CLIP_DEFAULT_PRECIS,DEFAULT_QUALITY,FF_DONTCARE,"Frutiger LT Std 45 Light");
And this text
Code:
s=_T("Let's try to calculate the size of this text");
and with MM_LOMETRIC map mode
GetTextExtent() returns me:
On screen: (1595,99)
Ink printer + print preview: (1589,100)
PDFCreator + print preview: (1580,100)
comparing with screen size the height is bigger but lenght is smaller. I don't understand.
I can understand that different printers process the fonts in different way and then to have different lenghts. That's not the problem. The problem is I need to simulate in screen the same behaviour i will have on printer because these texts are being aligned in the document, and I don't want to see that the text si aligned different in text than in paper.
What can I do to render the text on screen with the same size I will have on the printer? Print preview is doing it. Should I change the font parameters? is something related with pixels per inch?
Im working on a small code and am trying to limit the size of the mysql databse string its pulling.
It can only be 119 characters, or less if its more i would like to do nothing, but if its meets the requirements it runs the script.
Code:
int32 message_id;
string_t message ="Is requesting some one to respond.";<_______________TEMP SHOULD BE THE POSTERS MESSAGE
string_t username = "Guest";<_______________TEMP SHOULD BE THE POSTERS NAME
// char will not be logged in so get the id manually

So here is where I'm heaving the problem
if(message is less then 119 characters run script )<<___________THIS IS THE CODE LINE IM TRYING TO LEARN

char buf[110];
sprintf(buf,"[Web Chat] %s %s",username.c_str(), message.c_str());

the point of this code is to increase character by 1 (so from a to b in this case). The underlined line is the line that the system is rejecting at the moment (but there may be other issues).
I am using Visual C++ to write an app. I write CMyObject class and may allocate a lot of instances of CMyObject object, so I want to reduce the size of CMyObject class.
What I can figure out to do is:
1. I can use the following code to get the accurate size used by a single instance of CMyObject object:
CMyObject Object;
//Get the size of memory allocated for CMyObject object
int nSize = sizeof(Object);
is that correct?
2.To reduce the size of CMyObject, I have several ideas:
(1)Change member function to static member function if it is possible, since each member function will take some spaces in the instance of CMyObject.
(2)Change virtual member function to member function if it is possible, since virtual member function may take more spaces.
(3)Eliminate unnecessary member variables to reduce spaces.
(4)Finally, if (1), (2) and (3) does not work well, then change CMyObject from class to a struct that only contains some member variables, thus will eliminate the spaces allocated for constructor and destructor of a class.
