Can't really see how the drawing would affect an event from being triggered (or messages from reaching intended window target)... post relevant code.

Hello All,
I wanted to create an application which do something, say popup message box after every 10 min. I wanted to create MFC application.And wanted to show running application icon in task bar (near clock). What should I do. Can you please suggest similar and how can I achieve same with C#?
Regards.

CWnd::SetTimer allows you to : say popup a message box every 10 min.
just put relevant code in CWnd::OnTimer
void CMainFrame::OnStartTimer()
{
m_nTimer = SetTimer(1, 2000, 0);
}
void CMainFrame::OnStopTimer()
{
KillTimer(m_nTimer);
}
void CMainFrame::OnTimer(UINT nIDEvent)
{
MessageBeep(0xFFFFFFFF);
MessageBox(HWND_DESKTOP,"Text here","Text here",MB_OK);
CMDIFrameWnd::OnTimer(nIDEvent);
}

Hello,
When I try to build the QuickWin source (download link: http://www.codeproject.com/KB/dialog/quickwin.aspx) I get some errors. I *have* done it (built it the same way) several years ago using an earlier version of Visual Studio.
Looks like it should be easy to overcome, but I'm not sure how to proceed.
Here's a good example to start with:
c:\projects\quickwin\quickwin\quickwin.h(28) : error C2504: 'CRedirect' : base class undefined
And here's the entire build output (BTW, I am *not* worried about warnings.):

You should post on the articles forum section for a better response.
Having said that, where does the CRedirect class reside.
You're either missing some file or some path is not set to find the include file.
Please check the additional include directories option in the project properties.

I need to get a registry value which is REG_MULTI_SZ, so I can get each name and go on to the next registry key and get the version number.
In regedit the values are
MSSQLServer
MicrosoftSMBiz
SQLExpress
The raw data that I pull out is. eg is verbatim
'M' '0' 'S' '0' 'S' '0' 'Q' '0' 'L' '0'
The end of each word is '0' '0' '0' and the very end is '\0\0\0\0'
My goal is to make a char array that can run through strtok_s,
So I wrote this, but overall in the end, I want to terminate the new array with '\0', so I can remeasure the length of characters. I wanted to return a value that is not the full 1024.
char rgValue[1024];
char szInstance[1024];
Get the Registry value
// do work
ndx = 0;
szRgVal = sizeof(rgValue);
for(int i=0; i < szRgVal; i++) {
if (!rgValue[i] == '\0\0\0') {
szInstance[ndx++] = rgValue[i];
}
else {
szInstance[ndx++] = ';';
}
i++;
}
maxStr = strlen(szInstance);
szInstance[maxStr-0] = (char)'\0';
I really wanted to terminate the char array at the end of the chars so I can get the strlen of 36 or so, but strlen is always 1033 1024.
MSSQLServer; MICROSOFTSMLBIZ; SQLEXPRESS;\0TTTTTTTTTT
Here is my question.
Is my for loop bad coding practice? Or should I try to add the '\0' in the for loop at the end of the chars I want, and then remeasure with strlen?
|
|
|
|

So I modified it a bit, and I got what I wanted, oh. I passed the value back the calling function as a char, and extracted the names out of the char array, and called the version registry function, so far no side effects.
ndx = 0;
doubleZero = false;
szRgVal = sizeof(rgValue);
for(int i=0; i < szRgVal; i++) {
if (!rgValue[i] == '\0\0') {
szInstance[ndx++] = rgValue[i];
doubleZero = false;
}
else {
if (doubleZero == false) {
szInstance[ndx++] = ';';
doubleZero = true;
}
else {
szInstance[ndx++] = '\0';
break;
}
}
i++;
}
maxStr = strlen(szInstance);
szInstance[maxStr-0] = (char)'\0';
printf(" SQL Server Instance: %s %i\n", szInstance, strlen(szInstance) );

if statement is very wrong
'\0\0\0' quote will be used as a single '\0' character
and the ! sign not the equation modifies to != , it will be a bool negation of rgValue[i] character and gives true when rgValue[i] is '\0' and false otherwise and this bool value will be compared to the '\0\0\0' value what is false as bool type
I recommend this:
ndx = 0;
szRgVal = sizeof(rgValue);
for(int i=0; i < szRgVal; i++) {
if (rgValue[i] == '\0' && rgValue[i+1] == '\0' && rgValue[i+2] == '\0' && rgValue[i+3] == '\0') {
szInstance[ndx++] = '\0'; break;
}
else {
if (rgValue[i] == '\0' && rgValue[i+1] == '\0' && rgValue[i+2] == '\0') {
szInstance[ndx++] = ';'; i++;
}
else
szInstance[ndx++] = rgValue[i];
i++;
}

I thought about that, how can I compare 2 bytes in a row with i that represents 1 byte. Didn't think about i+1 and i+2 and so forth.
I had the right idea at least!
After I wrote the first version I posted, I started wondering if I was crazy, in the way I handled the returned value.
I wasn't expecting a code rewrite that is paste and go!, but I thank you for taking the time to do so. Nice to know I was on the right track, and I actually learned something this week.
Sincerely

This part doesn't work, it never registers, I ran the code through debug and stepped through it, but it's hard to follow the 3 zero sequence.
Day is over, get back to it tomorrow, no worries I will figure it out.
else {
if (rgValue[i] == '\0' && rgValue[i+1] == '\0' && rgValue[i+2] == '\0') {
szInstance[ndx++] = ';';
i++;
}

One word: UNICODE.

I thought about that last night,
Should I just left it as unicode, so it don't run into the lang issue down the road when I make the french version.
|
|
|
|

Stop, stop!
You have totally misinterpreted the data you are looking at. This is a Unicode (aka UTF16) string where each character is 16 bits wide rather than the 8 used by ASCII. You must either convert the string to ASCII in order to process it correctly (via WideCharToMultiByte()[^]), or make your program Unicode aware. I would also be interested to know how you are extracting this value from the registry as I was under the impression that strings are automatically converted for non-Unicode programs.

You are making a dangerous mistake in this code, in that you are mixing ANSI and Unicode, but without fully understanding it. You should change all your char declarations to WCHAR or switch the project setting, Character Set in General properties, from Unicode to Multi-byte.

Today I will fix the 2 registry programs, I was thinking wchar_t, but I'll go with WCHAR.
The following registry function , is ran after the one I posted above, so you can get an idea of what I'm doing. I wrote the char stuff by myself, with no help, hope it passes. I started changing the code to wchar so I know the code doesn't work, it's just foresight.
I run the first program, return the values and seperate the names, and then loop through the names with the program below to get the versions
wchar_t* CA_Registry::_get_SQLServer_Version( const wchar_t *szSQLInstance )

HKEY keyHandle;

int iRegPath_Prefix = strlen(szRegPath_Prefix);
int iRegPath_Suffix = strlen(szRegPath_Suffix);
strncpy_s(szRegPath, _countof(szRegPath), szRegPath_Prefix, iRegPath_Prefix);
strncat_s(szRegPath, _countof(szRegPath), szRegPath_Suffix, iRegPath_Suffix);
int buffSize = (int)strlen(szRegPath) + 1;
LPWSTR lpRegPath = new wchar_t[buffSize];
MultiByteToWideChar(CP_ACP, 0, szRegPath, buffSize, lpRegPath, buffSize);

I had to read it a couple of times before it soaked in, those are huge refinements, but I get it, way more optimized, and it teaches me that alot of the stuff was not needed. Let me make the mods, and I will alter the other registry function I have as well. I didn't know I had to wprintf, I thought it was just for printing to the screen in console.
Thanks

This is the calling function just for reference, I wrote it from scratch, no help, lot cleaner than the registry functions I wrote. It's a rough draft, needs more detail, but in the end, after searching by wire, then search the local machine registry, if nothing is found, I will ask if they want to download the X86 or X64 version, and install it using an automated script that I write on the fly. It's starting to shape up now.
