The characters show up in the list box as short unreadable characters. like it is chopped.
If i change to : Sendmessage(hndl, listboxupdate,0 , (LPARAM)&buf[15]);
Then I can see readable valid strings of up to 50 characters and then empty unreadable characters afterwards. I tried all kinds of things , including using CString, still did not work.
Now i want to convert this into a unsigned char pointer.
unsigned char * pBMPHeaderData;
I already got the raw image data in another unsigned char buffer.
unsigned char* pRawBMPData;
Now i want to make a complete BMP image by adding the header info and raw data into a new unsigned char pointer. For this i need to convert the BITMAPINFO struct into a unsigned char *
I am having problems copying outputs of the above code into other unsigned char other[32]. I need to keep the output of dev/urandom for backup. But, when I try to assign the values by memcpy(other, key, 32), the values do not match. The same problem happens by assigning values index by index in a loop.
I've got something I'm trying to accomplish, but crashes my program.
I've got my server and client code.
Having the client send a message they type (char Chat[1024]) And the server receiving the chat (char recv_chat[1024]) only to send it to all connected clients again. Which the server sends the recv_chat.
The client receives it (char recv_chat[1024]). This works, and the client gets the right info. However, I'm trying to store it using a vector. I'm sure I've tried any way possible.
Client storing vector pseudo-code:
vector<char*> SaveChat; int main () { while (true) { if (newClientConnected) {
[Code]....
This doesn't work, and crashes my application. I've tried changing the vector to string, const char*, basically anything I can with no avail.
I am having some trouble performing this. I am not sure, if my unsigned char arrays are null terminated, but I don't think so. Here is my code: They are supposed to be byte arrays of size 16.
int setkey(unsigned char* ky) { printf("INSIDE POLY-DEL ... key byte array passed in HEX: "); int i; for (i = 0; i < (int)16; i++)
How do you use char instead of unsigned to calculate numbers? This is using char only and nothing else.
Step 1: I ask the user to enter a number. Step 2: User enters a number. Step 3: Number user entered is going to be that number squared or cubed or w/e.
For example; "Enter a number: " 3 " Number you entered multiplied four times: " 81 (Since (3)*(3)*(3)*(3) = 81)
Another example; "Enter a number: " 5 " Number you entered multiplied four times: " 625 (Since (5)*(5)*(5)*(5) = 625)
Code: Char num; cout << "Enter a number"; cin >> num; cout << "Number you entered multiplied four times: " << (num)*(num)*(num)*(num) << endl;
I came across some code and it's not clear why it is casting an unsigned char * to another pointer type only to free it right after. Here are the relevant structures:
As you can see, _Edge_Message has a *msg field, but in the function below, they cast it to the other two structure types inside the case blocks of the switch statement only to free it. What is the point or advantage of doing this?
Code: void _edje_message_free(Edje_Message *em) { if (em->msg) { int i; switch (em->type) {
I have an embedded microcontroller system communicating with a similar system by radio. The api for the radio requires data to be transmitted as an unsigned char array. It will always transmit a positive integer in the range 0 to 255.When I receive the data I am having difficult in extracting this positive integer.
Code: unsigned char rxData[4]={'1','2','3',''}; int inVal=0;
//want to assign inVal whatever number was transmitted
E.g. 123
I've been at this for a week and have tried at least 10 different approaches including the use of the atoi(), copying the absolute value of each element of rxData into another char array, reinterpret_cast, and others.
I need fastest method to reverse order of bytes in my char array.
For example i have:
unsigned char buf[8]; // consider data stored in buf is 88 77 66 55 44 33 22 11 // how to reverse it to: 11 22 33 44 55 66 77 88 // currently i can do it by equal assignment , i make another buf like: unsigned char buf_ok[8];
[Code] ....
// This does reverse the bytes as i want but its very slow , i am looking for fast method ..
Where col is a 'vec4' struct with a double[4] with values between 0 and 1 (this is checked and clamped elsewhere, and the output is safely within bounds). This is basically used to store rgb and intensity values.
Now, when I add a constant integer as a pixel value, i.e.:
buffer_rgb[i] = ((unsigned char)255;
Everything works as it should. However, when I use the above code, where col is different for every sample sent to the buffer, the resulting image becomes skewed in a weird way, as if the buffer writing is becoming offset as it goes.
You can see in the 'noskew' image all pixels are the same value, from just using an unchanging int to set them. It seems to work with any value between 0-255 but fails only when this value is pulled from my changing col array.
Whole function is here:
// adds sample to pixel. coordinates must be between (-1,1) void Frame::addSample(vec4 col, double contrib, double x, double y) { if (x < -1 || x >= 1 || y < -_aaspect || y >= _aaspect) {
Okay so i have everything right accept transfering the selectedindex from listbox in form1 to listbox in form2. I am using the below string item to hold the selected line of the list box, with the intent of recalling and then adding it into the form2 listbox. I get a not implemented error and i can't figure out why. I know the information is moving with the variable item, it just doesn't get printed out to the new listbox.
How can i write a function that will read an "unsigned integer" into a variable of type "unsigned short int"? i can not use cin >> inside the function.. so i am looking for atleast a hint!
int myfunc( int a, int b, char * c ) char a = "(int)myfunc()"; char b = "(int,int,char*)" call(a, b, ...) // Function name and return type, params
I want to do function what registers forward what will get callback if the time is right. Basically then i dont need to edit and add extra functions into source files. I just have to include header and use register forward function. If there is anything close to this it would be perfect!
I am trying to assign the integer value to unsigned char array. But it is not storing the integer values. It prints the ascii values. Here the code snippet
The values which are stored in uc[] is ascii values.I need the integer values to be stored in uc[]. I tried to do it with sprintf. but the output is not as expected. if I print the uc[i] it should diplay the value as 0,1,2....99.
I have a property sheet view with few property pages. One of this property page contains a HTML representation via a CHtmlView derived class.
Initially, the .html file is correctly rendered. The problem is that sometimes switching between properties pages sometime the html file is not redraw. The behavior appears randomly.
According to Spy++ in such situation some Windows messages are not sent by WebControl (Internet Explorer_Server layer): WM_ERASEBKGRD, WM_PAINT or WM_NCPAINT.
Approaches such Q179421 or Q183161 are not useful. My machine runs IE 10.
The windows hierarchy is: Shell Embedding -> Shell DocObject View -> Internet Explorer_Server.
Any workaround that would determine Internet Explorer_Server layer to send these messages always?
I am currently working on a MFC application and need to send (non-document) files created by the program over email. (either with SMTP client on the machine or web mail)
I have searched the web and some forum and cannot find a code that work. They either have errors, or not Unicode compliant, even when converted they still don't work.
Everything code example seems to use MAPI, but like I said non of them worked.

A simpler approach would be to modify or override the event handler OnFileSendMail() that is built into MFC document view framework and use the menu id ID_FILE_SENDMAIL.
To get this feature all you have to do is give any menu item the resource id ID_FILE_SENDMAIL and MFC will call the installed mail client for you. The problem is MFC will attach any open document that is in focus when you select the menu item. The file that I wish to send is not associated with the document so I was wondering if there is a way to find the OnFileSendMail() handler and modify it to send my file instead. I am not too keen on how MFC route command handler such as ID_FILE_NEW, ID_FILE_SENDMAIL etc. These methods/functions are hidden from view or I don't know where to find them.
I am working on an application that should send mails to some recipient. I got a mail address tarek@abcd.fr use it to send a mail to tarek@gmail.com. each time I execute my program I got the following message when I send DATA "553, that domain isn't allowed to be relayed thru this mta (#5.7.1) ovh"
I tried to change my port from 25 to 587 (even 465) but I got the same result.
