Hello there,
I found a wayout to check for the end of stream.
<br />
using (BinaryReader br = new BinaryReader(fs))<br />
{<br />
while(fs.Position<fs.Length)<br />
{<br />
}<br />
}<br />
...assuming that "fs" is defined as the FileStream in the outer block.
Hope this works...

Hi all,
Can anybody tell abt the VB's chr() function equivalent in vc++ ?
|
|
|
|
|
In C++ doesn't exists. 
Example:
VB:
Chr(13)
C++:
char mychr = 13;
|
|
|
|
|
One is not really needed in C++, but the compiler mite complain.
Implicit conversion:
char ch = 10; // compiler mite complain
Explicit conversion:
char ch = char(10); // compiler happy
Explicit conversion:
char ch = (char)10; // compiler happy
INTP
Every thing is relative...

we are trying to create a login for our application, but its not working, we know that we need the code to check against the database to see that the password and the login is correct but our code doesnt seem to work.
The code is:
If my.User.isauthenticated then
Textuser.text=my.User.name
If userexixts(my.user.name) then
Textpassword.focus()
Else
MyNewUser = true
Messagebox.show("Please chose the Reguest Account link")
End if
Else
messagebox.show("Contact help if you are a Auckland University Staff member")

What do you mean by "doesn't seem to work"?

You will have to describe in more detail on "not working", what happened, which line of code causing error, any error message. Without know what are the inputs, and what your functions (isauthenticated, userexists) doing, nobody can help you.
You should first do a debug by tracing how the code flow. If you can't do that (due to not able to use debugger), you can print out the values and look at why it doesn't work according to your intention.
There's no such thing as "not working". It's either working, or not working as intended.

Hi. I have two winform one of them have region tranparency ("foreground" form); the other no ("backgroung" form). I want to move the background form and make the foreground form move with it. Any ideas?
Thanks a lot, Gonzalo.

|
|
Well, in the Move Event of the Background Form, add this code :
ForegroundForm.Location = BackgroundForm.Location
I haven't tested it though, but it should work.

Hello DotNet group,
I have a general question in regard to running an insert command using a sqlDataSource.
I have a gridview that displays things that can be inserted into my database.
I now can select an item from the gridview (just one), and run the insert.
But, I might want the user to select multiple items in the gridview, and then perform an insert of these items (like 2 or 3 or whatever). I have a button to click when it is time to do the insert, the insert does not happen when the user clicks the "select" button in the gridview. What would be a good way to handle performing the insert on multiple items?
My first thought would be to create an array (in the code-behind page) that would hold the items to insert (in this case single integers), and set up a loop that reads the array values, and runs an insert for each item.
Any other ideas will help.
Thanks,
eric
Thanks for the information!

I have developed a SmartDeviceApplication in Visual Studio 2003 that connects to a SQL database. It works when it runs in the Visual Studio pocket pc emulator but when I try to run it on the pda itself an error occurs when it trys to connect to the database. The error reads:
SmartDeviceApplication1.exe TypeLoadException
Application::run+0xf
Form1::Main+0xa
I'm wondering if it errors because I need to install sql server ce on the pda? And if it needs to be installed, how do I do it? Or is there something else I need to do? Please help!
Thanks for any help you can provide.

Hello there,
I have a Requirement class. I wanted to instantiate a number of objects of the same class. So I created a array of Requirement object. Here is what I had:
<br />
dim req() as Requirements<br />
<br />
Private sub CreateRequirements(num as Integer)<br />
for i as integer=0 to num<br />
req(i) = new Requirements<br />
next<br />
<br />
end sub<br />
Above code gives an error like "Object reference not set to an instance of an object". Can someone help me out?
Thank you,

You should Redim the array first:
dim req() as Requirements
Private sub CreateRequirements(num as Integer)
Redim req(num) as Requirements
for i as integer=0 to num
req(i) = new Requirements
next
end sub
|
|
|
|
|
Thank you. It solves the problem but does not need "as Requirements" for the Redim statement.
I have another question. If you do not know the size at a time and I want to create the Requirement object dynamicly, do I need the Redim statement?

Just curious: Do you have a hard reason why you need to use an array as opposed to an arraylist?
It would handle all the resizing issues for you and, if needed, you can always generate an array from the ArrayList using ToArray().
Q.
|
|
|
|
|
This statement:
dim req() as Requirements
only declares a reference to an array of type Requirements. It doesn't instantiate it.
You need to initialize the reference to an instance of an array of that type before you can start assigning values to it.

Hello there,
I am trying to perse a word document by reading the style property of each paragraphs. Here is what I have so far:
<br />
dim myDoc as new Document<br />
dim pp as Paragraph<br />
dim str as String<br />
<br />
myDoc = CType(GetObject("test.doc"), Document)<br />
for each kk in myDoc.Paragraphs<br />
if Mid(kk.Style.ToString(),1,12) = "requirement" Then<br />
str = kk.Range.Text<br />
SaveData(str)<br />
end if<br />
next kk<br />
"requirement" is a name of style I have created in the test document. In short how I can read the stylename for the paragraph? Can anyone please let me know what is wrong with this code.

I've created a PrintDocument and have used PrintPreviewDialog as I'm designing it to preview the document... The PrintPreviewDialog appears EXACTLY how I want it to print, but when I print the document it shifts every item on every page to the right. It seems to increase the left margin.
Any suggestions on where too look or what to do?
Thanks,
Andrew
