Hi to all, long time no see.
Recently I had to make some modification to my app. When I was done I've tried to rebuild the project but I've got numerous errors like:
- "d:\program files\microsoft platform sdk for windows server 2003 r2\include\shtypes.h(102) : error C2011: '_SHITEMID' : 'struct' type redefinition",
- "d:\program files\microsoft platform sdk for windows server 2003 r2\include\shtypes.h(120) : error C2011: '_ITEMIDLIST' : 'struct' type redefinition",
and so on ....
Now it may be I've downloaded other platforms or so could this be it or...?
How can I fix this?
Thanks in advanse.
P.S.
VS6, WinXP SP3

Hai!
I am using the following sorce code to display JPEG images in my Win CE application developed using eVC++ for a pocket PC device.
http://www.pocketpcdn.com/articles/jpeglib.html
Actually i get a bitmap handle by using the above source code, i display this bitmap handle on my picture control.
Actually i am displaying the image with its original size, but i am not able to see the whole image as the size of screen of my WIN CE device is very small, so i want to display compressed image or display the image after reducing its size?
Is there any function to do it?
Thanks!

My DLL [^] performs such task. You may use, as well, the GDI+ for the purpose.

Also StretchBlt[^], which has the advantage of definitely being available of any WInCE build, but the disadvantage of using a lousy resampling algorithm.

I have to use skip list to store ~109000 words from a text file.
Here's the code (I'm using Visual C++ 2008):
Struct of the node:
struct SkipNode
{
SkipNode ** forward;
CString mots;
CString longe;
CString pos;
};
Make a new node:
SkipNode* make_node(int level, CString mots, CString pos, CString longe)
{
SkipNode *sn;
sn=new SkipNode;
sn->forward = (SkipNode**)calloc(level + 1, sizeof(SkipNode *));
sn->mots = mots;
sn->pos = pos;
sn->longe = longe;
sn->level=level;
return sn;
}
Insert a node:
void insert(SkipList* ss, CString value, CString pos, CString longe)
{
int i;
SkipNode* x = ss->head;
SkipNode* update[MAX_LEVEL + 1];
memset(update, 0, MAX_LEVEL + 1);
for(i = ss->level; i >= 0; i--)
{
while(x->forward[i] != NULL && x->forward[i]->mots < value)
{
x = x->forward[i];
}
update[i] = x;
}
x = x->forward[0];
if((x!=NULL)&&(x->mots!=value)||(x==NULL))
{
int lvl = random_level();
if (lvl > ss->level)
{
for(i = ss->level + 1; i <= lvl; i++)
{
update[i] = ss->head;
}
ss->level = lvl;
}
x = make_node(lvl, value, pos, longe);
for(i = 0; i <= lvl; i++)
{
x->forward[i] = update[i]->forward[i];
update[i]->forward[i] = x;
}
}
}
My MAX_LEVEL = 17 (log109000).
I read that skip list takes less time to insert a node than some other data structure (O(log n)). So I wonder why I need ~3 minutes to make the skip list above. And when I stop debugging, the program is still running!? I've just started studying programming, please help me!

What that defines is how the insertion time grows with n. It does not say that the skip list insertion time is less than the time taken to insert an item into other data structures.

Pass things like CStrings BY REFERENCE. In this case, by const reference:
void insert(SkipList* ss, const CString & value, const CString & pos, const CString & longe)
SkipNode* make_node(int level, const CString & mots, const CString & pos, const CString & longe)
Other data structures probably have better characteristics for this
- vectors are nice because they've been optimised - it's generally reckoned that if you're going to be reading from and searching in your data structure a lot, you're best off using a vector, sorting it and using std::lower_bound to search.
- std::map or std::set has probably been better optimised
- A trie[^] or alternatively a ternary search tree[^] is generally reckoned to be good for storing words

Thank you so much I'll try it out. My professor asked me to use skip list to make a dictionary, so I don't have any other choice.

Hi,
I am getting a string from the server , and doing following operation to get the BYTE format of that
string key;
This variable contains the value, which I received from server.
BYTE key1[24] = {0};
DWORD dwBase64Size;
CryptStringToBinary(key,0,CRYPT_STRING_BASE64,0,&dwBase64Size,0,0);
if (dwBase64Size>24)
return "";
CryptStringToBinary(key,0,CRYPT_STRING_BASE64,key1,&dwBase64Size,0,0);
This function is working fine for WINXP, but fails on Win2K, as it does not allow the dll to get registered.
In the same way the prolem is with CryptBinaryToString also.
can you suggest a alternate of this code, which works on WIN2K.
Thanks

Why don't you try to build your own [^]?

Hi,
I was playing with edit control,
after entering a number
Accidentally i pressed CTRL + SHIFT keys.
This sent the text to right align..
How to over come this..
|
|
|
|
|
Goto Edit box Properties select styles. you can see a combo box. change it per your needs.
|
|
|
|
|
Keeping the property to align left.
On debugging if we press ctrl+shift together,
the text will shift to right align.
|
|
|
|
|
are you asking a question?
If its a question, then i don't think if you press SHIFT + CTRL during debug the text will shift to right align
|
|
|
|
|
It will shift..
try ur self
|
|
|
|

Dear,
Below are the steps i followed to create the problem.
1. Created the simple dialog based app. And placed the editbox control in dialog.
2. style align property of the editbox is set as left.
3. Run the app in debug mode.
4. enter some text in edit box.
5. press ctrl + shift keys as u mentioned . The text remains at the same place ie left . ie no shift .
Hope u have tried it in VC 6.0 and if there is any change in our approach kindly reply back.
|
|
|
|
|
your approach is correct
if u have set the property to left align then.
while debugging you need to press right side ctrl+shift(near to arrow keys)
this will surely shifts the cursor to right side.
once it is in right side if u press left side ctrl+shift
it comes to left..
Plz try again and reply

hallo, how can i blind out Effects, color, Script, underline , struck through in CFontDialog?
i used this code but it did not work:
CFontDiaolg m_cfdlg;
m_cfdlg.m_nFlags |= ~CF_EFFECTS; // did not help
m_cfdlg.m_cf.Flags |= CF_NOSCRIPTSEL;// only disabled but not blind out
|
|
|
|
|
It should be
m_cfdlg.m_nFlags &= ~CF_EFFECTS;
«_Superman_»
I love work. It gives me something to do between weekends.
|
|
|
|
|
thanks for the answer but it did not work.
|
|
|
|
|
The fact that it did not work could be related to the flag not being the right one.
The example shows the following.
Assume the m_nFlags variable currently contains the value 0x99999999.
Further assume the CF_EFFECTS field is the value 1.
To remove CF_EFFECTS from the m_nFlags variable,
Do a bitwise NOT of the CF_EFFECTS.
~CF_EFFECTS will give the value 0xFFFFFFFE.
ANDing m_nFlags and ~CF_EFFECTS will now give you 0x99999998, which is then re-assigned back to m_nFlags.

Thanks alot ist worke, but i still have another problem with the script element:
m_cfdlg.m_cf.Flags |= CF_NOSCRIPTSEL; // Disabled but not blind out the script element
m_cfdlg.m_cf .Flags &= ~CF_SHOWHELP; // Disabled the Help Button, but the Question mark in the Dialog still showed.

I am building legacy application in VS2008 solution. I have the followng lines in my code
template <class MapType, class DestinationType = MapType::referent_type>
class MapCopy
{
public :
typedef DestinationType destination_type;
typedef typename MapType::value_type source_type;
static HRESULT copy(destination_type* pTo ,source_type *pFrom)
{
}
on building this project i am getting the following error
error C2664: copy' : cannot convert parameter 2 from 'const std::pair<_Ty1,_Ty2> *' to 'std::pair<_Ty1,_Ty2> *' C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\atlmfc\include\atlcom.h
How to getrid of this error?
Regards

Check this page for details on Compiler Error C2664[^]
Possible solutions specified in MSDN
1. Recheck the prototype for the given function and correct the argument noted in the error message.
2. Supply an explicit conversion if necessary.

Could it be as simple as adding the "const" declaration to the second type?
