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 and then display a link to the HTML file. my html basically looks like: ImageFilename.html

is this coding correct? -
is this coding correct?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...?
-
is this coding correct?yes :) i store those image descriptions to a HTML
// Save the stream to disk System.IO.FileStream newFile = new System.IO.FileStream(Server.MapPath(sSavePath + sFilename), System.IO.FileMode.Create); newFile.Write(myData, 0, myData.Length); newFile.Close(); TextWriter tw = new StreamWriter(Server.MapPath("Images/Saved Images/" + sFilename + ".html")); // write a line of text to the files tw.WriteLine("<html>"); tw.WriteLine("<img src=\"" + sSavePath + sFilename + "\">" + " " + "<desc=\"" + desc.Text + "\">" + " " + "<mat=\"" + materials.Text + "\">" + " " + "<date=\"" + date.Text + "\">"); tw.WriteLine("</html>"); // close the stream tw.Close();right now i have to solve this function... and next is the toughest part since not using DB.. which is the Searching :) -
is this coding correct?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?
-
is this coding correct?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))) { Response.Write("<script type=\"text/javascript\">var result = confirm('Image already existed. Click OK to overwrite. Click NO for new filename.')</script>"); } -
is this coding correct?ok finally thanks for ur constructive response......... so it's possible to use javascript on asp.net for that? im doing a simple website that allows users to upload image (simply copy/paste image from other folders to my application/images folder). also additional functions.. one of them is to validate whether the image i'm going to upload already existed.. if yes, ask user for input yes/no, if yes overwrite, if no, change a new filename. i downloaded the sourcecode from here http://www.codeproject.com/KB/aspnet/netimageupload.aspx also from there modify. atm im stuck at this function... later i'll have to do a Search function on the webpage. that is to search via descriptions/properties of the image not just the filename and i'm not allowed to use DB for that (tho its quite easier right)?
-
is this coding correct?ok i'll rephrase my question, i'm doing asp.net with c#. for this particular function, i need to use VB input box in c# to validate user input. i've read http://www.mdibb.net/net/using\_the\_visual\_basic\_input\_box\_in\_c/ but it doesnt seem to work as it says MessageBox.show does not exit in current context. PS: christian, if you don't feel like answering is ok, no one is forcing you. and btw this forum doesn't state its not for beginners. if you have no patience teaching, then don't. ;P
-
is this coding correct?heh i might missed the entry, sorry about that. i know i'm not an expert but please at least if you're not gonna provide something constructive, then shut it. for sure a book may help but if thats the option i wouldn't post here lol.
-
is this coding correct?string sFilename = System.IO.Path.GetFileName(myFile.FileName); string ans; while (System.IO.File.Exists(Server.MapPath(sSavePath + sFilename))) { Console.Write("Do you want to overwrite? (Yes/No)"); ans = Console.ReadLine(); Console.WriteLine(""); while (ans = Yes) { } logic: check if image already existed when uploading, if yes, ask user for input yes/no, if yes overwrite, if no, change a new filename. im lost.. plz help
-
Prompt user for Input1.sorry but what do you mean by server application? i'm doing asp.net c#.. images upload 2. oh path.combine works too? oh so ty lol
-
Prompt user for Input// Make sure a duplicate file doesn’t exist. If it does, keep on appending an incremental numeric until it is unique string sFilename = System.IO.Path.GetFileName(myFile.FileName); string ans; while (System.IO.File.Exists(Server.MapPath(sSavePath + sFilename))) { Console.Write("Do you want to overwrite? (Yes/No)"); ans = Console.ReadLine(); Console.WriteLine(""); } lblOutput.Text = "File already existed. A duplicate file has been created"; the logic is upload file -> if file exists -> prompt for user input -> if yes -> overwrite -> if no prompt for user input for new file name the code is not finished.. but am i on the right path??

Need Help on Writing to New Line// Save the stream to disk System.IO.FileStream newFile = new System.IO.FileStream(Server.MapPath(sSavePath + sFilename), System.IO.FileMode.Create); newFile.Write(myData, 0, myData.Length); newFile.Close(); TextWriter tw = new StreamWriter(Server.MapPath("Images/Saved Images/info.txt")); // write a line of text to the files tw.WriteLine(txtFName.Text + " " + txtLName.Text + " " + IDTextBox.Text + " " + sSavePath + sFilename); // close the stream tw.Close(); it works but whenever i try to upload 2 or more files/images... it will just overwrite the exisiting texts.. how do i make it such that it will create a new line each time i upload an image upon the existing ones?
