Hi Lokesh,
It's been a while since I dealt with this issue. But the URL works just fine. I just tested it. Might've been a hiccup at the Microsoft end, or perhaps you cannot access it for some other reason? But rest assured, the website is there.
I can't upload the code. I would be violating Microsoft's ToS. Please visit the web-site in the link.
As for your second question, you can't. The IMsTscAx is an interface exposed by the Remote Desktop ActiveX Control. What you need to do is instantiate the RDAC itself, and query it for the IMsTscAx interface. I can't remember the RDAC's CLSID value out of the top of my head, so you'll need to use the OLE/COM Object Browser tool in order to determine it. It might be the CLSID_MsRdpClient2 you discovered) Once you have the CLSID, call CoCreateInstance with it and query for the target interface. If this fails, ask the object for IUnknown first and use the returned pointer to query for the IMsTscAx. All COM objects support IUnknown, so if you have the CLSID correct, you should be able to get it at least. If the IMsTscAx interface query returns a failure through IUnknown::QueryInterface, at least you'll have more details on why and how it fails.
As for the reasons why the 'Connect' call refuses to work, I can't say. There are numerous reasons why a Remote Desktop connection may fail, and not all of them are related directly to code. Perhaps the service is disabled? Perhaps access is prohibited? You should first try to connect to the Remote Desktop service by manually using the RDS software (Found in Start -> Programs -> Accessories -> Remote Desktop Connection). If you can connect manually to the host computer, then try the code-wise approach.
Regards,
Antti

I need a windows control that has multiple radio buttons in a row, to allow the user to select and deselect a number of options specific to a single item.
Does this exist, or is the only way to roll my own?
If I have to roll my own is the a good article to look at?
Thanks

Are you talking about having a row of radio buttons, from which the user can select one ?
Then the answer is control grouping. Take any dialog template. Then place the row of radio buttons there. Now, go to the Tab Order option, and make sure that the radio buttons are set into an ascending order so that the first radio button has and index, say, 6, the next is 7 and so on, until the end of the row. Then go to the properties of the first radio button, and check the option 'Group'. All other buttons must NOT have the Group option set.
The Group option works so that the first control in the tab order that has the Group option set becomes the first member of the group. All adjacent controls (in the tab order) of similar type belong to the same group until a) another similar control with the group option set is met or b) a different type of control is met.
To access this group code-wise, add a member variable to the first radio button control, and take it's value. The value returned is a zero-based index on the radio button that is selected. Like, it's 0 if the first one is selected, 1 if the second and so on..
For a good example, go here[^].
Remember that the radio buttons can be vertically, horizontally or diagonally placed on the dialog. The tab order determines how they are grouped, not their physical position.

Yes, kind of, the only trouble is that its purpose is to allow the user to select/deselect 0 or more types that a particular row on a database table is applicable for. This means that at runtime every row returned from the database needs to have one of these multi-row radio buttons next to it. I was going to use a Listview control in report view with one of these multi-row radio buttons attached to each item. And then in the OnOK handler for the dialog I would set up the database links according to the types selected for each row.

If the items are mutually exclusive, use checkboxes instead.

The items arent mutually exclusive, hence 0 or more types. Zero types could be set or 3 of them or all of them. It needs to be a unified control so that I can have one of them for each row in the Listview that have been returned from the database.

Exactly my point. With radio buttons, one and only one in a group is selected. With checkboxes, all, some, or none of them can be selected. If you are allowing 0, 3, or all types to be set, then a checkbox is your only option.
In your original post, you likened it to a "voting control." When you are voting for a group of related items (e.g., size of pizza, score of an article), you only get to select one of them. If the items are mutually exclusive (e.g., toppings on a pizza, favorite programming language), then you can select any number of them.

Sorry when I referring to "Voting Control" I was talking about the look of the CodeProject article voting control, rather than its function.
OK, if we change this to a row of checkboxes where 0 or more items can be selected. I still need it in the form of a single control that would be able to return its state and live in each of the rows in the Listview control

No problem. I've used this control for exactly that purpose. For each row was the name of a scheduled job in column 1, and in the other dozen or so columns were the different permissions (e.g., read, write, execute, delete, manage) for that particular job. Worked great.

Hi,
I am having some problem with property sheet.
A property page contains static text and one command button (namely "Click")
When we press the Click button on a property page then static
text should be Changed or hide.
What should we write code?

try,
((CWnd*)GetDlgItem(YOUR_STATIC_ID))->SetWindowText("the text");
good luck.

Hi,
Please help me!
How use ProgressCtrl to present runing program in another main form?
Thanks
|
|
|
|

You need to do what ? Could you be a bit more specific ?
If you need to use a progress control, familiarize yourself with CProgressCtrl class in MFC. This class represents a progress control that can be stepped through to represent the advances during a lenghty operation.

Unless you know how long the other program is going to run and how long it has run (e.g., it has run 13 of 17 minutes, so the control will reflect 76% completion), a progress control is of no use here. Make sense?
You might want to further explain what you are after.

I have a CWebBrowser2 control on my dialog. I navigate it in a worker thread.
It works on mostly computers, but on a few computers it can't browse the URL content.
I have monitored these status:
"NavigateError"
"NavigateComplete2"
"DownloadComplete"
"DocumentComplete"
On those computer that the CWebBrowser2 control refuse to work there is no "NavigateError", but after "DownloadComplete" there is nothing to happen, so I think there is something wrong in the display process, but I have no idea about the wrong and how to solve it. (winXP,win2k, ADSL)
Any suggestions?

Hi,
I have defined a new TreeCtrl in my project with checkboxes. What I would like to do is, that these checkboxes have a third state. Not only checked and not checked but also, the third state from the normal checkboxes (checked but disabled).
Is there any way to do this without bitmaps??? 
Thank you in advance!
Xia.

I have constant connection to the .mdb '97 file and use local variables for executing temporary queries:
CDaoQueryDef query(&db);
query.Create("", NULL);
query.SetSQL(strSQL);
query.Execute(strSQL);
...
query.SetSQL(strSQL);
query.Execute(strSQL);
When i execute 1000 INSERT/DELETE statement, I have more than 35MB memory lost, but when I comment just the execution lines, I have no memory losts.
Is this some DAO enternal caching that may allocate memory, cause I can't find any other reason?

i wrote the following code
FILETIME ftNow;
SYSTEMTIME ftSys;
FILETIME ftTemp;
GetSystemTimeAsFileTime( &ftNow );
FileTimeToSystemTime(&ftNow,&ftSys);
SystemTimeToFileTime(&ftSys,&ftTemp);
here the problem is
ftTemp.dwLowDateTime != ftNow.dwLowDateTime
why?
but if i use
CoFileTimeNow(&ftNow) instead of GetSystemTimeAsFileTime( &ftNow );
the code works fine
why?
does any one know about it?
how can i get the actual file time as ftNow from the system time.

In either case, the wMilliseconds member of the SYSTEMTIME structure is the same. Since the GetSystemTimeAsFileTime() function does not need granularitry beyond milliseconds, the extra value can be ignored.

Is that considered good or bad?
I just read a paper by Bjarne, where he used
Vector::Vector(int i) : sz(i), v(new int[i]) { }which I never do myself.
If heap allocation is needed, then I initialize the pointer with NULL in the member initialization list (MIL) and allocate the memory with new in the ctor body. But if you're using standard compliant tools that throws correctly if new fails, then it's perhaps OK to do it in the MIL.
Any thoughts on this?

i write a global CBT_HOOK function in a win32 DLL ,and i want to send a message to the DLL's calling windows.But it doesnt work. Here is my code:
HWND hCallWnd = NULL;
LRESULT CALLBACK CbtProc(int nCode,WPARAM wParam,LPARAM lParam)<br />
{<br />
switch(nCode)<br />
{<br />
case HCBT_CREATEWND: SendMessage(hCallWnd,MyMsgID,0,0);
break;<br />
}<br />
return CallNextProc(nCode,...);<br />
}<br />
void InstallHook(HWND hcallwnd)<br />
{<br />
SetWindowsHookEx(WH_CBT,CbtProc,DllHandle,0);
hCallWnd = hcallwnd;
}
the Error is : in InstallHook() function,the hCallWnd's value is correct. But in CALLBACK CbtProc() function, the hCallWnd's value is always ZERO! so my SendMessage() doesnt work at all.
Who can point out reason ?
|
|
|
|
|
The DLL is loaded into the address space of each process and each process gets a separate copy of the global variable. You need to put hCallWnd into a shared partition.
