The wave files are included in the project.
In the code, PlaySound() is called.
Before formatting my PC, it works.

But I what else should I install to make it work...

You did not answer my question. Does sound work at all on this machine, or does it just not work via code?

The sound device is ok. Only the program cannot play the wave files now.

Other programs like windows media player amd games can play sound. Only my program cannot.
2 computers have the problem after formatting.

What are the attributes of the sound you used? I mean the sampling rate, bit, etc. May be some driver mismatch after formatting? Did you try with some other wavs?

I am NOT sure the wave attributes.
I am in office now.
I will try to replace the project wave files by windows wave files.
Thanks for you suggestion.

Hey guys, I'm having some problems adding a groups to a list control object. Here is what I'm trying:

LVGROUP group;<br />
ZeroMemory(&group, sizeof(group));<br />
<br />
			// Set group<br />
			group.cbSize = sizeof(group);<br />
			group.mask = LVGF_HEADER | LVGF_GROUPID | LVGF_ALIGN;<br />
<br />
			// Convert string value to LPWSTR value for group.pzHeader<br />
			LPWSTR header = new WCHAR[printableAttributes->name->size() + 1];<br />
			MultiByteToWideChar(0, 0, printableAttributes->name->c_str(), -1, header, <br />
				(int)printableAttributes->name->size() + 1);<br />
<br />
			// Set Group name<br />
			group.pszHeader = header;<br />
			group.cchHeader = (int)wcslen(group.pszHeader);<br />
<br />
			group.iGroupId = index;<br />
			group.uAlign = LVGA_HEADER_CENTER;<br />
<br />
			listControl->InsertGroup(index, &group);<br />
<br />
			// Temporary variables<br />
			NonCompositeJob* temp;<br />
			LVITEM item;<br />
  <br />
			// Insert items into group<br />
			for(int i = 0; i < (int)((CompositeJob*)job)->getNoJobs(); i++)<br />
			{<br />
				ZeroMemory(&item, sizeof(item));<br />
				item.iItem = i;<br />
				item.mask = LVIF_GROUPID;<br />
				item.iGroupId = group.iGroupId;<br />
				item.iSubItem = i + 1;<br />
<br />
				temp = ((CompositeJob*)job)->getJob(i);<br />
<br />
				//Name<br />
				listControl->InsertItem(i, (LPCTSTR)printableAttributes-><br />
						name->c_str());<br />
<br />
				//Total Copies Printed<br />
				listControl->SetItemText(i, 1, (LPCTSTR)printableAttributes-><br />
						totalNumberOfCopiesPrinted->c_str());<br />
<br />
				//Job Status<br />
				listControl->SetItemText(i, 2, (LPCTSTR)printableAttributes-><br />
						status->c_str());<br />
<br />
				//Job Type<br />
				listControl->SetItemText(i, 3, (LPCTSTR)printableAttributes-><br />
						type->c_str());<br />
<br />
				//File Size<br />
				listControl->SetItemText(i, 4, (LPCTSTR)printableAttributes-><br />
						fileSize->c_str());<br />
<br />
				//File Location<br />
				listControl->SetItemText(i, 5, (LPCTSTR)printableAttributes-><br />
						fileLocation->c_str());<br />
<br />
				listControl->SetItemData(i, (DWORD_PTR)temp);<br />
				listControl->InsertItem(&item);

groups is the LSVGROUP object and item is the LVITEM. index is the index of the list control object(listControl). CompositeJob is an object that holds 2+ print jobs.

In the loop, I'm trying to add the items one at a time and getNoJobs returns the number of jobs inside of the CompositeJob object. After creating the group, I try to add each item to the group, I set the text of the fields that will be displayed for each of the objects in the group, return to the top of the loop, and continue for each job in the CompositeJob object.

When I add 2 composite jobs to the list, I end up with 4 entries, two for each one.

Have you tried replacing the second InsertItem call with MoveItemToGroup. The result you are seeing is what I would expect with 2 InsertItem calls.

Re: Groups in List Controls

Alex Cohn16-Oct-07 1:35

first, call listControl->InsertItem(&item);
Your first call

<br />
 //Name<br />
listControl->InsertItem(i, (LPCTSTR)printableAttributes-><br />
name->c_str());<br />

should be converted to

<br />
listControl->SetItemText(i, 0, (LPCTSTR)printableAttributes-><br />
name->c_str());<br />

BTW, why do you cast to LPCTSTR? If you have your Unicode setting right, it should compile cleanly without the cast; if your Unicode settings are wrong, the cast will not help at runtime.

Cheers,

Alex

Hi all,

I am doing multiple SQL statement into the database. But what to do when the database connection was dropped or lost. Is there a function I can use to test the db connection before performing the SQL statement?? or is there another technique I can use ??

Many thanks in advance

Are you using SQLExecDirect()? If so, what does it return when you try and interact using a dropped connection?

Hi David,

Thanks for your reply, and I must say point made. Yes I am using SQLExecDirect(), can I use the return message to establish whether a connection exists or not?

Thanks again

I haven't check it yet, but it would make sense to use the return message, the return code is -1. But the return code when a sql error occurs, is also -1. Thus going on the return code is not accurate, but I can get a hold of the return message. Which I can use to see what the real problem was. Making use of SQLGetDiagRec(SQL_HANDLE_STMT, hstmt, 1, sqlState, &nativeErr, Msg, sizeof(Msg), &TextLengthPtr); function.

Thanks for the advice David.

A Q&D way to ensure that you are correctly roundtripping to the RDBMS and successfully executing SQL is to execute something like:

select 1

-or if using Oracle:

select 1 from dual

   If you get back a successful return code with a result column of "1", then you know everything is working correctly.

   Note: this is a fairly heavyweight solution to what may be an easy problem, depending on the API(s) you have avaialble for your target RDBMSes. But it might be easier than decoding error messages from different RDBMSse...

   Peace!

Such as,software can produce electronic album
I have no idea,please introduce some skills about this.
Sorry,My english is not very good. Sniff | :^)

In order to create a .exe file, you first need to become very familiar with the PE file format. As you are an obvious beginner, I would advise against it. Stick with something more on your skill level.

If you want to write a compiler that can create .exe files then you need to know about the PE (Portable Executable) format. This defines the header format and internal layout for executable files on Windows. There are articles on Code Project about the PE header format and Microsoft have some Knowledge Base articles on in, there are tools on www.sysinternals.com and on Code Project for examining PE headers and you'll probably want a book or two on compilers as well. Good luck.

Nothing is exactly what it seems but everything with seems can be unpicked.

Hi All,

I need to decrypt a file encrypted by a php script..it can be any algorithm which is good enough and cannot be cracked easily..if it cannot be cracked at all will be the best solution..but for now i am just looking for any of the encryption algorithm that can encrypt the data good enough not to be cracked..easily...and that can be decrypted easily using VC++...can someone help me out in doing the same..I need it very urgently...any of the algorithm..Rijndael..or Blowfish or anyone..but it can also be decrypted easily..

Thanks a lot..
