Then you should reply in the already existing thread instead of starting a new.
ahmad25 wrote: string s = "select picture from tiff";
string str = Path.GetFileName(s);
As the string s doesn't contain a file path, using it in a call to GetFileName doesn't give you any meaningful result.
Despite everything, the person most likely to be fooling you next is yourself.

What is this supposed to return??
You are calling the fill method with "" as you sqlcommand
path.getfilename("c:\\x\myfile.jpg") returns the extension of a file

Try the Following
I assume that you know to add custom actions for a web setup.
follwing are the answers (Piont wise).
1. Use SQLDMO Namesspase for detecting the sql server. (You can add a form to the Installer for user to speciy the server name, or you can read the system where you are trying to install.)
2. For this step you have to add a action script again and a user interface form.
3. you can use a option of desktop shortcut folder. (Drag the home page. and drop in the desktop shortcut folder.)
4. repeat the step 3. but drop in program shortcut folder.
5. you can user readme dailod. or use a custom action to launch the file either in notepad or word pad.
6. You can convert whole MDF file to a sql script. and Using SQLDMO you can execute the script on the selected instance in step 1.
7. Using SQLDMO run the scripts for inserting the values.
8. rolling back is handled automatically by the installer (But customaction exceptions should be handled carefully).
Thanks & Regards
Pete

I am trying to setup a site where I connect to an SAAS system via an iframe in my default.asp page. However I seem to be having troubles getting the iframe to pass a variable in the URL.
Here's what I'm trying to do. If I click on the following link, I am immediately logged in as a guest at the SAAS site. Just pasting the link in my browser works correctly.
http://www.mywebapp.com/home/login.asp?FromLogin=1
However, if i use the same URL an iframe, it doesn't seem to pass the variable because I end up at the login page.
<iframe src="<a href="http://www.mywebapp.com/home/login.asp?FromLogin=1">
Can anyone provide a suggestion? This is driving me nuts!
Thanks in advance for your help!

Hi,
I have a web app in asp.net 1.1 . I've created resource files (.resx), and need to add images to it that can then be displayed using the html img tag. How do I load images into .resx files? Should I be loading the image or a path to an image?
Also, I'd like to place all resource files in a sub-directory in the root, and then have them be compiled and placed in a dll in the bin dir. How do I do this? As of now, the only option I see is that I place all the .resx files in the root, and VS will compile them, and place them in a dll in the bin folder. I'd like to see the many .resx files in a dir of their own. How do I do this, and have the vs compiler find them?
Thanks.

public class GridViewTemplate : System.Web.UI.Page, ITemplate
{
private DataControlRowType fTemplateType;
private string fColumnName;
CheckBox rowCheckBox;CheckBox headerCheckBox = new CheckBox();
public GridViewTemplate(DataControlRowType type, string colname)

fTemplateType = type;
fColumnName = colname;
headerCheckBox.ID = "hdrCheckBox";
}
public void InstantiateIn(System.Web.UI.Control container)
{
switch (fTemplateType)
{
case DataControlRowType.Header:
container.Controls.Add(headerCheckBox);
break;
case DataControlRowType.DataRow:
rowCheckBox = new CheckBox();rowCheckBox.ID = "chkUserCheckBox";
container.Controls.Add(rowCheckBox);
break;
}
}

Hi friends,
I have to create a Message board. I'm planning to create a class for this, whick is going to include a collection of messages. This is the general idea:
MessageBoard Class
UserId
Collection of Messages
AddMessage()
RemoveMessage(messageID)
MarkAsRead(messageID)
MarkAsUnread(messageID)
Message Class
MessageBoardId
Text
Read
I have read some about Collections I saw some examples where they use ArrayList, SortedList and CollectionBase among others for this. What do you think is the most suitable Collection type to use in this case?
Thanks a lot

Put the control in a div tag perhaps.
I didn't get any requirements for the signature
|
|
|
|
|
Well, I tried even putting a div element with its scroll property set to auto. Was helpless.!?!
Muthu
|
|
|
|

some properties to try setting on your div tag.
style="width:300px; display:block; overflow: scroll; height:200px;"
I didn't get any requirements for the signature

Instead of div, you can also use a panel control and set the corresponding properties like haight and scrollbars

I want a js function using confirm js function to determine whether the user wants to exit the current page, by the onunload js event.
That is when user unloads a page, there must be a confimation, whether user really wants to exit.
When i press ok, i must retain the current page. if cancel is clicked then current page must be closed.
any sample piece of code available..Thanks for reading..
Muthu

See the js function in the post message here at codeproject
If you have something writen and try to go back or toa new page, it asks you if you really want to do that
Alexei Rodriguez

what is the subject name? i could not find, unless i have some keyword.?!
Muthu
|
|
|
|

No, i meant:
Go to "New message" as if you were gonna post a new message and see how it works
You are gonna have to look for that js function,, maybe it is embeded in the html or maybe it is in an external .js file

I am running into an issue with the fileupload control.
Standard code... just a test After clicking on button1 I do get the Yay response. Clicking button1 again right after, I get the Nay response. However, if I choose a file and then click on button1 and it has a file, I get the Yay response and the text in the upload control clears. I refresh the page, and I get the Yay response. Is there a way to control this?
protected void Button1_Click(object sender, EventArgs e)
{
if (this.FileUpload1.HasFile)
{
Response.Write("Yay!");
}
else
Response.Write("Nay!");
}
|
|
|
|
|
That is how the file up load works. The file upload control will post the file only once.
Think about it. If you have a file selected by the user, would you want that file to be sent to the server on every additional postback?
protected void Button1_Click(object sender, EventArgs e)
{
if (this.FileUpload1.HasFile)
{
Response.Write("Yay!");
//Implement method to save file
}
else
Response.Write("Nay!");
}
I didn't get any requirements for the signature
|
|

|

I understand that's how it should work. And no, I don't want the file to be sent on every postback. Just if you click an upload button with a file in the upload control, and a user clicks refresh on their browser, the same action is performed and the upload control still is showing HasFile = true. I'm trying to not let the code to add a file run again if a browser refresh is performed after clicking upload.
