I am unable to check if the character in the 2D array is alpha
here is my code
#include<iostream>
#include<cctype>
#include<cassert>
#include<cstring>
const int maxChar = 20 ;
using namespace std ;
int main() {
int count = 0 ;
char d[2][20] = { "hi" , "di" } ;
[code]....
I made this function to check in string is alpha only or alphanumeric but always give me alfa way ?
Code:
int checkIfStringisAlfa(const char str[]){
int lenStr = getStringLength(str);
int i = 0;
int ret;
for(i = 0; i < lenStr; i++){
if(str[i] >= 'a' && str[i] <= 'z' || str[i] >= 'A' && str[i] <= 'Z'){
//printf(" alfa
[Code] .....
How i could go about extracting and checking if the very first character in my string array is an alphabet
View 2 Replies View RelatedI found a targa loader that works great and implemented it in my code.
But for some reason, the alpha region of my texture , just won't be alpha when I load the Texture in my code.
If I make a texture that is a full purple colored rectangle, and carve out the central part with an alpha zone, in-game the quad is all full purple, instead of having the central part being transparent.
I tried the following code too, and it doesn't work, I don't understand
//NPC
glEnable(GL_BLEND);// Enable Blending
NPC00->Draw();
glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);// Set The Blending To A Nice 50/50 Mode
glDisable(GL_BLEND);// Disable Blending
Draw Function, basically draws a Quad and applies the texture to it.
I'm just trying to get textures with alpha to work, I usually work with targas, so thats why I got a targa loader.
I want to check whether a certain character is in a string or not but my code is not working
Code:
#include<stdio.h>
#include<string.h>
int main()
{
[Code].....
Code:
char value;
printf_s("enter:");
if (scanf_s("%c", &value) != 1)
{
printf_s("oppppssss
");
}
else
{
printf_s("ok");
}
I wanted to check whether the input is a character or not, if a character is given then the output suppose to be "ok", but the output is always "oppppssss", where is the problem here?
I want to create 2 functions to (1) convert a passed string into proper case (capitalize the first alpha character of a string and every alpha character that follows a non-alpha character); (2) sort the array of names (after it has been converted to proper case).
I tried these two:
console.writeline (lower.toUpper());
void bubblesort (string array[],int length);
but I don't know if they are good.
Can we do this :
Code:
char strings[][100]={"ABC","EFG","IJK","LKM"};
char temp[100];
temp=strings[1];
I am trying to make an add-on to IE. This add-on doesn't have any tool bar or any UI.
I am just taking the details of currently loaded HTML page. Basically it is for manipulating one dialog box. I want to get access to the DOM COM interfaces of the dialog box.
Since it doesn't have any button I didn't impliment IOleCommandTarget. I implemented only IObjectWithSIte.
My RGS file contain following in addition to my COM related entries
HKLM
{
NoRemove SOFTWARE
{
NoRemove Microsoft
{
[Code]...
But I couldn't see my add-on working or even not loading to IE.
I have an *.lct file. I like to read *.lct file and save an bmp image.
I can not read this file using usual file read.
Code:
void CLCTtoBMPDlg::OnBnClickedReadlctfile() {
CFileException CFileEx;
CStdioFile ReadFile;
CString OpenlctfilePath;
TCHAR szFilters[]= _T("LCT Files (*.lct)");
CFileDialog fileDlg(TRUE, _T("bmp"), _T("*.lct"), OFN_FILEMUSTEXIST | OFN_HIDEREADONLY, szFilters);
[Code]...
Find the attachment. change the file extension *.lct instead of *.txt. I like to read ASCII Data into Hex, Example : Data "A" as "41" (Refer the jpeg image). How is possible?
I have some trouble with DLL. I created a dll with function
double square(const double * args)
and then in my application defines
typedef double (*MyFunct)(const double *args);
I use LoadLibrary and GetProcAddress to get the function address and cast it to MyFunct. Everything works fine except that when I pass a double *, for example 0x08800350, to the DLL function, the argument becomes totally something else, for example, 0x0aa00460.
I have no clue what happens to the argument value.
I am having a strange problem trying to display a dialog from a UI thread. The dialog simply fails to display. I have a function DisplayFlashBox(), which creates the UI thread:
CUIThread* CIMUIHelper:: DisplayFlashBox(const CString &sMessage, const int nInstrumentUID) {
CUIThread *pThread = new CUIThread();
pThread->SetString(sMessage);
pThread->SetInstrumentUID(nInstrumentUID);
pThread->CreateThread();
[Code] .....
The dialog doesn't display. When I tried debugging, I found the OnInitDialog() method of CIMFlashBox class doesn't actually return. Very strange. I tried calling the DoModal() method instead of Create, but doesn't display the dialog either.
My MDI Project(VC++2010 Professional) is unable to catch errors ,though I return ,try catch block. So I developed simple dialog based application .Placed one button on Dialog and on its click written following code
Collapse | Copy Code
void CMFCExecDlg::OnBnClickedButton1() {
try {
int j = 0;
int i = 10/j;
}
catch(CException * e) {
MessageBox(_T("Hello"),_T(""),MB_OK);
}
}
But still program control does not come in catch block it simply gives error. I tried all child classes of CException but no use.I think there will be some setting in Visual Studio. How to handle exceptions
I have main thread that creates an WebBrowser2 COM object. and i want to invoke JScript functions on it from another thread. i try to use GIT but still doesn't work for me.. there is a problem with marshal WebBrowser2 for JScript?
View 4 Replies View RelatedI'm trying to append data to a CFile using FILE* But when execute the application, it always give error saying "No such file or directory". I can actually see the file created but it just keep giving error "No such file or directory".
Is the file being lock or the file just created so it can not be find by fstream(FILE*)? or the file mode is wrong?
Below is the code:
[QUOTE]
void SaveDocument(CString strFile) {
CFile file;
if( !file.Open(strFile, CFile::modeCreate | CFile::modeWrite | CFile::shareDenyNone)) {
CArchive ar(&file, CArchive::store);
// save now.
MyClass.Serialise(ar);

Attached is the printscreen of the FILE* pointer. the pointer is evaluated as bad pointer. Why the FILE* pointer not able point to the file being created?
So I have this problem with not being able to iterate over a vector in a nested for-loop. Here's the nested for-loop:
bool innerHit = false;
for (std::vector<Sprite*>::iterator outerIter = sprites.begin(); outerIter != sprites.end() && (!sprites.empty()); outerIter++) {
Sprite* spriteOne = *outerIter;
for (std::vector<Sprite*>::reverse_iterator innerIter = sprites.rbegin(); innerIter != sprites.rend() && (!sprites.empty()); innerIter++) {
Sprite* spriteTwo = *innerIter;
[Code] .....
What happens is, after having called the collisionDestroy-function and the program tries to execute the nest loop in the outer for-loop, it all crashes with the text "Expression: vector iterator not decrementable", which I understand is because the iterator will have already become useless. The question is: know this, how do I fix it? I can't seem to get a hang of it.
Here's the collisionDestroy-function (the collisionReaction does nothing but sets a few local variables):
void Enemy::collisionDestroy(std::vector<Sprite*>& sprites) {
for (std::vector<Sprite*>::iterator iter = sprites.begin(); iter != sprites.end(); iter++) {
Enemy* tmp = dynamic_cast<Enemy*>(*iter);
if (this == tmp && collisionType == 3 || collisionType == 1) {
sprites.erase(iter);
break;
}
}
}
I want to change the alpha of a sprite without changing any other colours
View 4 Replies View RelatedI want to use a new color for BaseColor in iTextSharp.
I can easily set a new color using RGB values from 0 to 255.
However, if I want to adjust the alpha value (and I know alpha ranges from 0 to 1), I can't make the alpha 0.5 because it's not an integer in the definition of BaseColor.
public BaseColor(int red, int green, int blue, int alpha);
So I can set my BaseColor like below:
static BaseColor newColor = new BaseColor(192, 192, 192);
but I can't use a non-int value for alpha. How can I easily convert double alpha values to integer values? What would be the range for alpha in int values and how do I, e.g., set the alpha value to 0.5 in int values?
EDIT: btw, I found online something like this: int alpha = (pixel >> 24). I don't understand why 24 and how can I break that into chunks I understand?
I use MFC Find console window and send key to console like this.
Code:
HWND w;
w = FindWindow(NULL, L"c:userspkrudocumentsvisual studio 2010ProjectsCleanVirusDebugCleanVirus.exe");

After program process success in console it not close console windows but it show like this in Output
The thread 'Win32 Thread' (0x1300) has exited with code 0 (0x0).
I think if I can check when VC will show this line, then I can use FreeConsole(); for close console windows.
I am looking for a way to sort a string just by the alpha characters, not by the ASCII table. Therefore
string sort(string name) {
sort(name.begin(), name.end());
return name;
}
will not work. And I am looking for the most simple way to go about it!
Code:
#include <stdio.h>
char * strcpy(char *restrict s1, const char *restrict s2);
struct item {
char title[20];
struct item *next;
} firstCard;
int main (){
strcpy(firstCard.next->title, "whatever");
}
I am unable to set firstCard.next->title
I have been trying to make a very simply programme that checks if the inputted information is an integer or not (i.e: that it contains no other characters).
I have tried using the isdigit function (but this only works for single characters). I have tried cin.clear, cin.ignore (1000) but this doesn't work either..
Any effective way to check if x in the following programme has been entered correctly
#include <iostream>
using namespace std;
int main() {
cout << "Please enter an integer (positive or negative)" << endl;
int x;
cin >> x;
HERE I WOULD LIKE CODE TO CHECK IF THE USERS INPUT IS VALID

When I step into CMainFrame::OnAlohaHowAreYou(), I found m_pDoc is NULL. If I remove the split views and make CMainFrame::OnCreateClient() like below, then there is no problem.

CFrameWnd::OnCreateClient(lpcs, pContext);

How to stalk a random alpha letter in order in a minimum possible way.. and write the cases which the container can be stalked.
for example.. ACMICPC can be a store in three stalks.
ACC
M -----------> three stalks
IP
