If you actually replied to my posts instead of yours, I'd get an email, and the threading on the forums would make sense.

Kind of. You can show prompts using javascript. However, once you've done a postback, your chance for javascript validation is over, I'd just show a message saying the filename already exists in a control on the page, asking them to rename it and reupload. That is, if you need to do that, overall, I'd take one of the other approaches I suggested ( rename it, put it in a DB, etc )

You're actually doing a paid project here ? Why can't you use a DB ?

thanks but i don't quite understand your sentence
"However, once you've done a postback, your chance for javascript validation is over"
it's a school project.. no idea as teacher said DB is unnecessary..is there any other way? i've done a simple but not yet complete code lol...
if (System.IO.File.Exists(Server.MapPath(sSavePath + sFilename)))<br />
{<br />
Response.Write("<script type=\"text/javascript\">var result = confirm('Image already existed. Click OK to overwrite. Click NO for new filename.')</script>");<br />
<br />
<br />
}

You're on the right track, but, your page will reload, then your file upload control is empty, and your message box pops up. You will need to do another postback, after the user selects the file again, to get anotehr shot at it. You could use AJAX, but even then, you can't access file paths from javascript. So, your only option as far as I can see, is to find a way to rename the files, or to store the files in folders so the names don't clash. For example, you could store it to a temp filename, store that name in the viewstate, then postback and ask for a new name or if you should overright, but you are better to ask that in the page, not with a popup.
Why can't you use a DB ? You're working on a photo site that needs to be searchable, but can't have a database ? For school, or for a client ?

i'm not sure whether the teacher is dumb or what lol. personally i think DB is so much easier and i have no idea why she said it's unnecessary not needed.
well, i guess i'd have to follow your path lol.i rougly know your idea.. is there a website guide that you could show me so that I can follow the guide?

OK - well, your only other option is to store the text in something like an XML file that you maintain. A DB would definately be easier.

yes  i store those image descriptions to a HTML
System.IO.FileStream newFile = new System.IO.FileStream(Server.MapPath(sSavePath + sFilename), System.IO.FileMode.Create);<br />
newFile.Write(myData, 0, myData.Length);<br />
newFile.Close();<br />
TextWriter tw = new StreamWriter(Server.MapPath("Images/Saved Images/" + sFilename + ".html"));<br />
<br />
tw.WriteLine("<html>");<br />
tw.WriteLine("<img src=\"" + sSavePath + sFilename + "\">" + " " + "<desc=\"" + desc.Text + "\">" + " " + "<mat=\"" + materials.Text + "\">" + " " + "<date=\"" + date.Text + "\">");<br />
tw.WriteLine("</html>");<br />
<br />
tw.Close();
right now i have to solve this function... and next is the toughest part since not using DB.. which is the Searching

Well, that's not much use. A single XML file with all your metadata is the most sensible way to do non DB search.

ok i got you... a single XML with all my metadata.. but i remember teacher mentioning about each image file -> each html .. nevertheless, is there any keyword i shld search online for any guide or maybe u could provide some...?

I would expect that having a single XML file with the file path as the key to storing/updating data would be best. The XmlDocument class is the way to parse XML and XPath is the language you use to do that. If you have a bunch of HTML files, then you can load those as XML, if it's XHTML, but how do you write the code to search ? Sounds messy. A single file with all the metadata, which you can then search, seems best, although it's a long way away from the ease of doing it with a database.

hi,
sorry to post again lol.
is there a basic code sample or guide for html search/parse/display?
on this search.aspx.. i have to do a search function whereby it'll search/parse my HTML files and look inside their's metadata for eg <desc> and then display a link to the HTML file.
my html basically looks like:
ImageFilename.html

Hi, the following code is about getting the right thread to run something left stoped before.
No need help here
private void AppendToRichEditControl(string msg)
{
if (InvokeRequired)
{
object[] pList = {msg}; // this line here
richTextBoxReceivedMsg.BeginInvoke(new UpdateRichEditCallback(OnUpdateRichEdit), pList);
}
else
{
OnUpdateRichEdit(msg);
}
}
private void OnUpdateRichEdit(string msg)
{
richTextBoxReceivedMsg.AppendText(msg);
}
What i want to now is why the use of the {}? why not ()? its wierd.

Because {} is the syntax for creating an array. IF you had more than one element it may be more clear
object[] pList = {msg, msg2, new object()}; // creates an array with three elements

Consider the code below:
<br />
int[] numbers = new int[] {1, 2, 3, 4, 5};<br />
This would initalise an array of 5 data locations (i.e int[4]).
The values would be set to the following:
numbers[0] = 1
numbers[1] = 2
numbers[2] = 3
numbers[3] = 4
numbers[4] = 5

The documents says right click on class in 'class view' and click on 'add > method'. I do not see this option.
Thanks

Even if such a method existed, you'd do better to learn to code. Just type your method in.
Odds are it's not in the express edition or something.

coding by hand is always fun but at least if the documentation says something, we should expect it to happen. And then wizards speed up things a little too. I am using VS team suite.

You can only add classes using the class view.
Cheers,

I don't know what documents you are referring to, but you cannot add methods using the "Class View" window. I think what the documents are referring to is the class diagram. You can right click the model of the class in the diagram and choose Add->Method.
|

It is in MSDN. Yes i did try the class diagram and it works there but as a previous VC++ user, I thought C# will provide the same functionality as well.

I'm getting issues while validating the phone number entry...i applied validation so that user could enter only digits as phone no...however it is creating problem if user acidently clicks in ph no box & tries to go to another entry...user gets error msg----"pleaseenter digits only" for even name !!!

Get it to not validate on an empty entry. A validator should have a field for that.

Simple return without doing anything from your validation function.
you can do that by checking the text if it is empty do nothing.

I have two classes (of my own creation) that I instantiate in my app.
public partial class MyForm
{
MyObject1 m_myObject1;
MyObject2 m_myObject2;
}
I have another class (ThreadData) that contains objects of those two classes as well (and I use the same names for the variables in this class as I do in the app).
public class ThreadData
{
MyObject1 m_myObject1;
MyObject2 m_myObject2;
}
In a function, I create an instance of ThreadData, and use clones of the app's objects to set the objects in ThreadData. When I try to compile, I get this message:
error CS0052: Inconsistent accessibility: field type 'MyForm.MyObject1' is less accessible than field 'MyForm.ThreadData.m_myObject1'
Even if I don't use Clone(), it still gives me the same errors. Why?

What's the accessibility on your MyObject1 type? m_myObject1 is public, so basically MyObject1 has to be the same.
|
|
|
|

Here's a better example of what I'm doing.
public class MyObject1 {}
public class MyObject2 {}
public class MyData
{
public MyObject1 myObj1;
public MyObject2 myObj2;
public SetData(MyObject1 ojb1, MyObject2 obj2)
{
myObj1 = obj1;
myObj2 = obj2;
}
}
public partial class MyForm
{
private MyObject1 myObj1;
private MyObject2 myObj2;
private void MyFunction()
{
MyData data = new MyData();
data.SetData(myObj1, myObj2);
}
}
That should be perfectly okay.
