Yes, I understand they are similar.

how to add a windows control(e.g. Button Control) to a collection
Suman
|
|
|
|
|
What kind of collection do you mean?
ArrayList list = new ArrayList();
list.Add(button);
|
|
|
|
|
'Declaring Collection
Dim mycol as collection
'If I have two button control button1 & button2, Then I want to add this two button to the collection so that I can control them using
"For each button in mycol " command
Thank you
Suman

|
|
|

Dim coll As Collection
coll = New Collection
coll.Add(Button1)
coll.Add(Button2)
Dim b As Button
For Each b In coll
b.Text = "Got you!!!"

hi
please send me source code for audio recording for incoming/outgoing voice.
advance thanks

Firstly your question is one of the vaguest I have heard. What exactly do you want to capture. Do you want to capture audio from a microphone plugged into your PC or from a modem or from a VoIP phone?
Secondly nobody will send you the source code. Most people however will be willing to help with a specific problem. I will forgive the rather aggressive and ignorant tone of your question as I am guessing English is not your fist language. Others may not.
So….. If you are really at a total loss try google. Its pretty good for general ‘How do I …?’ type questions.
(It wasnt me who voted you a 1 by the way. In case you dont know a 1 vote means somebody was a little bit annoyed by your post).

Hello,
I want to initialize a variant in VB6. I want this variant to hold a double arrary. To do so, I did the following .
<br />
Dim a(0 To 6) As Double<br />
Dim Points As Variant<br />
<br />
a(0) = 0#<br />
a(1) = 0#<br />
a(2) = 0#<br />
a(3) = 0#<br />
a(4) = 0#<br />
a(5) = 1.2<br />
<br />
Points = a
This piece of code does not give me any error on compiling as well as on run time. but the trouble in "Points" in not filled. and when it is passed to one of the activeX controls I am using, it has nothing in it. I think I am not doing enough to intialize the variant. Can any body suggest me the right way of doing it.
thanks
|
|
|
|
|
This code will create a variant array named Points that holds 6 elements of type Double. If it isn't being received by the activeX control, then something else is wrong. How is the receiving function defined, and how are you passing it?
----------
There go my people. I must find out where they are going so I can lead them.

Here is how I am sending it
Dim a(0 To 6) As Double
Dim Points As Variant
Dim np As Long
Dim nr As Long
Dim b(0 To 1) As Double
Dim Radii As Variant
a(0) = 0#
a(1) = 0#
a(2) = 0#
a(3) = 0#
a(4) = 0#
a(5) = 1.2
b(0) = 9.5
b(1) = 8.9
Radii = b
np = 2
nr = 2
MyCtrl1.Insert_Polycylinder np, Points, nr, Radii, "cap"
!!!!!!!!!!!
And here is how my control recieves it
STDMETHODIMP StreamCtrl::Insert_Polycylinder(int pcount, VARIANT * points_var, int r_count, VARIANT *radii_var, BSTR capping)
{
if (m_pView)
{
HPoint *points = new HPoint[2];
int dummy;
float *radii = new float[2];
char capping_char[4096];
ConvertToChar(capping_char,capping,4096);
GetPointArrayFromVariant(points_var, &points, dummy);
GetFloatArrayFromVariant(radii_var, &radii, dummy);
Insert_PolyCylinder(pcount, points, r_count, radii, capping_char);
}
return S_OK;
}
and then
Here are other relevent functions
void StreamCtrl::GetPointArrayFromVariant(VARIANT * varKeys, HPoint **arrayfloat, int &length)
{
int len;
GetArrayFromVariant(varKeys, (float **)arrayfloat, 0, 0,len);
length = len/3;
}
void StreamCtrl::GetArrayFromVariant(VARIANT * varKeys, float **arrayfloat, int **arrayint, char **arraychar, int &length)
{
length = 0;
VARIANT jArray;
VariantInit(&jArray);
if ((varKeys->vt & VT_TYPEMASK) == VT_DISPATCH) {
IDispatch* disp =
(varKeys->vt & VT_BYREF ? *varKeys->ppdispVal : varKeys->pdispVal);
DISPID DISPID_GET_SAFEARRAY(-2700L);
DISPPARAMS dispParams = {NULL, NULL, 0, 0};
HRESULT hr = disp->Invoke(DISPID_GET_SAFEARRAY, IID_NULL,
LOCALE_USER_DEFAULT,
DISPATCH_PROPERTYGET, &dispParams,
&jArray,
NULL, NULL);
if (SUCCEEDED(hr))
{
length = jArray.parray->rgsabound[0].cElements;
if (arrayfloat)
*arrayfloat = new float[length];
else if (arrayint)
*arrayint = new int[length];
else if (arraychar)
*arraychar = new char[length];
for (int i=0;i<length;i++)
{
VARIANT *res = (VARIANT *)jArray.parray->pvData+i;
if (arrayfloat)
(*arrayfloat)[i] = res->dblVal;
else if (arrayint)
(*arrayint)[i] = res->intVal;
else if (arraychar)
(*arraychar)[i] = res->bVal;
}
}
}
}

Hi,
I am working on VB application in which i want a textbox to accept only integers and few other characters.
like for house no I want only integers, #, / and backspace to be allowed. I wrote code it restricts alphabets only, not other alphabets.
If KeyCode >= 48 And KeyCode <= 57 Or KeyCode >= 35 And KeyCode <= 44 Or KeyCode = 45 Or KeyCode = 47 Or KeyCode = 8 Then
txtDoorNo.Locked = False
Else
txtDoorNo.Locked = True
End If
but its not working properly.
plz help ASAP.
With Regards  ,
Chandan Kumar

End If
If you are using vb6 try to use the code keyascii = 0 or in vb.net use e.handle = true or e.handle = false
Try to test it.

Looks like the logic is not being expressed rigorously. Perhaps a few parenthesis would help.
If (keycode >= 48 and keycode <= 57) _
or (keycode >= 35 and keycode <= 44) _
or keycode = 45 _
or keycode = 47 _
or keycode = 8 then

salam every one
i want ask again about data base with vb.net
iam working in project to build compiler to c++ not proffetional one but its project to compiler class
iam stop now in type cheking that takes about check if the type for the identefier correct or not
i was storing the data type as reserved in tabel and i connected this with the vb.net program to show if the string that i have it from reading it from text foun in data base or not
if found return it from data base if not found insert it as identefier with it's type
like when i type (int x;) in text and read it as line store it in string and convert this string to char array
and take int alone and search about it in the database if it found in data base return int
and take x alone too and search about it too if not found in the data base insert it as identefier x type int
what is the sql statment that i can use it
i know it is select and insert statement but how i can use it correctly
if i can do this one (type checking) it will be easy with parssing too
thanks alot and iam sorry to this long letter

Hi,
What vb.net form events do we use when we need to detect if the "up" arrow key has been pressed? (down and up)
Right now, I am programming a simple "mario" game. When I press the up arrow key once, Mario has to jump up and land down in one smooth motion, just like in the original Nintendo Mario game.
The Mario character is represented by an Imagebox displaying the mario cartoon character.
I use the key down event handler but the problem is, once I let go of the up arrow key, Mario immediately stops. If mario is in the process of jumping up, it will just stop there in mid air. I have to press the up key continuously for the jumping motion to complete smoothly.
What event handler and keyboard code should I use for the "press a key once" event?
|
|

|

There is no event to handle directly for Arrow keys. Yes if you are talking about regular keys like A,B etc then keypress event will work. on Your situation use form level variable
on KeyDown Event set the time in that variable and on key up check the time of keydown and this way you can calculate that how much time the key was pressed . or if it has no concern with your applicaiton then only use KeyUp event of the container .
