I'm trying to add Microsoft IObjectSafety Interface to my code. I send string "MyParam" from JavaScript and catch it in my C# code like this:
private string myParam = "Empty";
public string MyParam
{
get
{
return myParam;
}
set
{
myParam = value;
}
}
After I add the IObjectSafety interface this doesnt work anymore, I get error interfaces cannot contain fields. How do I get the MyParam without using fields?
This is the code:
public interface IObject
{
[DispId(1)]
string MyParam; <--- error
};
public class WMC.PlayerLoader : IObjectSafetyImpl, IObject
{
#region [IObject implementation]
private string myParam = "Empty";
public string MyParam
{
get
{
return myParam;
}
set
{
myParam = value;
}
}
#endregion

Are you sure that an interface[^] is the correct mechanism for your problem?
One of these days I'm going to think of a really clever signature.

I need to add the IOBjectsafety interface to get rid of the message ActiveX might not be safe message when using it locally, I don't think there is any other way around that except verisign. All the methods on the interface work fine except getting that string.

Your implementation of MyParam is a property, not a field. You should declare this as string MyParam { get; set; } in the interface definition (which overcomes the interface containing fields error as well).

I've newer done this like that before. Do I need to change anything in this, or should it work as it was?
public class WMC.PlayerLoader : IObjectSafetyImpl, IObject
{
#region [IObject implementation]
private string myParam = "Empty";
public string MyParam
{
get
{
return myParam;
}
set
{
myParam = value;
}
}
#endregion

Fair enough, but isn't that a great big hint as to which forum you should post this question in instead?

How do you programmatically expand a url link to its true location?
Do you know about tinyurl.com and baidu.com? Baidu.com is a search engine that tries to discourage people from using their web site to make metasearch engines by hiding their links in a way that is a lot like how tinyurl.com works. TinyUrl.com is a web site where, if you want to present someone with a link to something and that link is long, you can use tinyurl to produce a tiny url for presentation purposes.
Anyway, what I want to do is to find a way to programmatically take the link http://www.baidu.com/link?url=mW91GJqjJ4zBBpC8yDF8xDhiqDSn1JZjFWsHhEoSNd85PkV8Xil7qccoOX3rynaE (the first link in a search for Jessica Alba using baidu.com) and have it return the actual link, http://baike.baidu.com/view/270790.htm . That is just one example. What I want to do is not specific to Jessica but for using Baidu.com as part of my group of search engines in my meta search engine project.
Maybe there is a way of using the WebBrowser class but I did not see a member that was the URL.
Maybe there is a way of using WebRequest and WebResponse.

By requesting the URL shown on Baidu. Then analyse the response. Somewhere there you'll find the redirection information, either in the HTTP header (e.g. a REDIRECT response code plus the correct URL) or a JavaScript in the HTML document, or something similar.
Do not forget that Baidu could find out that you do too many surch requests, and just stop responding to your requests (e.g. block your IP address).

I am a VB.NET Programmer learning C#. One of my applications I transfered over to C# via an online converion tool. I am receiving an error which I do not see why it's causing an error.
What I have now is:
try {
if (System.IO.File.Exists(srcedest) == false) {
My.Computer.FileSystem.RenameFile((dest), newName) sheet.Cells(row, 1).value;
}
} catch (Exception ex) {
txtLog3.AppendText(sheet.Cells(row, 1).value);
}
With the error of "expecting ;" at the "sheet" in My.Computer.FileSystem.RenameFile((dest), newName) sheet.Cells(row, 1).value;
Why would this cause an error since you don't put a ";" until the end of a statement?
Thanks in advanced.

Dunno, maybe remove the newName) and stick a ) just before the ; ?

My.Computer.FileSystem.RenameFile((dest), newName) sheet.Cells(row, 1).value; Your second line isn't the same as the first one. The reason is down to the fact that in the VB line, it's attempting to put sheet.Cells(row,1).value into the optional parameter newName. In your version, you don't do that - so the statement ends after the call to RenameFile.

Using a parameter name followed by a := means that you create that variable on the fly and assign the value to it. Just think of two statements:
string newName = sheet.Cells(row, 14).value + "_" + sheet.Cells(row, 15).value);
My.Computer.FileSystem.RenameFile(dest, newName);
|
|
|
|
|
Try to change to this line
My.Computer.FileSystem.RenameFile((dest), newName = sheet.Cells[row, 14].value + "_" + sheet.Cells[row, 15].value)

a) don't use bold: it's shouting!
b) what have you already tried for yourself?
c) one question at a time.

To add to that;
- It's a lousy subject line; doesn't tell us anything about your problem.
- You're not urgent to me. Why would it, just because it's included in the subject?
- Don't use text-speak. We're not sms-ing, and you don't pay by the character.

Depends. Read the documentation that comes with the SDK. Yes, it's called "research".

By having each known fingerprint known in a table, and executing a query to verify it's authenticity.

I have a c# .net project that has a button on the form. When the button is clicked twice, bad things happen. How do I disable the button?
I've tried disabling my button as follows but it doesn't work.
btn_Program.Enabled = false;
I've searched for this online, but every solution seems to reference asp.net. I don't think I have that, do I? I'm fairly new to c# and visual studio, so I may have it and not know it.
I liked the following discussion, but again, it refers to asp.net.
http://stackoverflow.com/questions/8473261/how-to-disable-a-button-after-1st-click[^]
The example I liked had the following code in it, but when I add it to my form class, it gets a compilation problem for ClientScript and Attributes:
static void DisableButtonDuringPostback(Page page, Button control)
{
StringBuilder sb = new StringBuilder();
sb.Append("this.disabled = true;");
sb.Append(page.ClientScript.GetPostBackEventReference(control, control.ID.ToString()));
sb.Append(";");
control.Attributes.Add("onclick", sb.ToString());
}
It said to add the following to Page_Load
DisableButtonDuringPostback(this.Page, Button3);
Compilation problems:
1. 'System.Windows.Forms.Button' does not contain a definition for id and no extension method id accepting a first argument of type 'System.Windows.Forms.Button' could be found (are you missing a using directive or an assembly reference?)
2. System.Windows.Forms.Button does not contain a definition for Attributes and no extension method Attributes accepting a first argument of type System.Windows.Forms.Button could be found (are you missing a using directive or an assembly reference?)
Any help would be very much appreciated.
