i am trying to test the c dll in vb. but while calling the function it is giving me the follwing error.
Unhandled exception at 0x77f75a58 in Project1.exe: User breakpoint
the call from vb is like:
Dim buf As String
Dim xml As Long
buf = " "
xml = xmlnode_GetXml(root, buf, 10000)
and the code in c is like:
long __stdcall xmlnode_GetXml( XMLNODE xnode, char* pBuffer, long lBuflen )
{
std::string s = ((XMLNode*)xnode)->xml();
long l = (long)s.length();
if( pBuffer && lBuflen>0 )
{
memcpy( pBuffer, s.c_str(), (lBuflen

You have to allocate the right amount of memory for your buffer variable.
For instance:
Const lBufSize=10000
Dim buf as String * lBufSize
xml = xmlnode_GetXml(root, buf, lBufSize)
I used a const to highlight the requirement that buffer size must match the one passed to the called function.
Hope that helps

It depends on how you want to connect.
If you are using a PABX you need a TAPI driver from the vendor and make an application which instructs the TAPI driver.
This is called CTI(Computer Telefony Integration) and CSTA (Computer Supported Telefony Application).

Hi, can anyone tell me how to disallow setting a property at run time like that of the Style property of a ComboBox where we are allow to set the style at design time but not via code.
|

In the Set code for your Property, check the status of the DesignMode property of your control. It'll return True of False depending on if your code is running under the forms designer or not.

Hi!
I have a string something like.
"#Title#CodeProject.#Description#The title name is CodeProject.#Summary#This is summary"
Which is stored in sql server and is rendered in powerpoint slides using automation using interop library. My problem here is I have to make any strings BOLD thats in between # and #.
Could someone please help
|
|
|
|
|
Does the automation library support RTF?
|
|
|
|

I dont know. coz i am hardcoding those strings with that are between "#" while inserting into sql table so that i could read anything that goes between # and make it bold.
please help

How are you moving the text into Powerpoint? What method calls are you using? Because it will be somewhere close to here that you will probably select the text between hashes, using the positions of the hashes in the original text, and set the bold attribute of the font for that text.
Example (pseudo code, you'll have to read up on how to really do this in Powerpoint VBA):
Dim oldText as string
Dim newText as String
Dim start as Integer, end as Integer
oldText = "I want #this# word bold"
start = Pos("#", oldText) ' Get pos of first #
end = Pos("#", oldtext, start) ' Get pos of first # after start pos.
newText = Strip(oldText, "#") ' Removed # from text
PPSlide.Insert(newText)
PPSlide.Select(newText, start, end)
PPSLide.Selection.Fond.Bold = true

Hi!
I am using vb.net and sql server 2005 as an winform environment and i am using Microsoft.Office.Interop.Powerpoint to render the data that i get from sql to powerpoint.
In a powerpoint textbox i have texts just like an in crystal reports( e.g. @value) as
:value and the code to render data
---
If Len(Trim(dr.Item(Strings.Right(Trim(ppItem.TextFrame.TextRange.Text), _
Len(Trim(ppItem.TextFrame.TextRange.Text)) - 1)))) > 0 Then
Dim s As String = dr.Item(Strings.Right(Trim(ppItem.TextFrame.TextRange.Text), Len(Trim(ppItem.TextFrame.TextRange.Text)) - 1))
s = s.Trim
ppItem.TextFrame.TextRange.Text = s-
----
Earlier, the bold text was hardcoded in ppt template slide. this created a layout problem e.g. overlapping text in a slide. now i just have one ":value" instead of multiples where i am concatenating every columns that i get from database. its working fine so far just except from making the text bold that are in "#"
sql code looks like
select '#Marketing & Publicity Points#'+char(13)+char(10)+cast(marketingpoints as varchar(5000)
----
please help

hi there,
i have a problem in conversion string to single, two textboxes have some alphabets and numerical values too
i want to comparision between them so i coded but its giving error
The error is: Input string was not in a correct format.<br />
Dim z, z1 As Single
z = Convert.ToSingle(zc.Text)
z1 = Convert.ToSingle(zc1.Text)
If z > z1 Then
MsgBox("It can not greater than other z")
zc.Text = ""
ElseIf z < z1 Then
MsgBox("It can not less than other z")
zc1.Text = ""
End If
someone know the solution

wow - that's some real world code if I ever saw it.
use Single.TryParse. Why is your data of type Single ?

mmm... some numerical values and alphabets , they can be in points
i just need numbers

OK, so you're saying that your problem is that you need to sanitize your data first ?

yeah, can you please stop questioning???? and let me know the solution???

Well, gee, if you made yourself clear, I wouldn't be asking you these questions.
Again, the TryParse method is the way to find out if your data is a number or not. If you want to find a number in your string, you can use a regex to find the number within the string, or you can use the split method on the string class, if the noise is always the same.
If that doesn't help, you need to explain yourself better. Probably with examples of the data you're dealing with.

How did you implement this communication? Sockets? Remoting? RPC?

communication under the Windows.so use common IP Address"127,0,0,1".i think it isconnect in Remoting.

This tells me you have code that sends a message between your client and server, but you don't have a single clue how how it works or what you used. How am I supposed to explain what you should be doing if you can't tell me what you're using?
