While I appreciate all the syntactic shortcuts Anders and friends are giving us in the C# language, I feel it's getting a bit ridiculous. We're quickly approaching a point where the shortcuts are making the code unreadable and harder to understand for noobs in favor of making it faster to type.
I suspect the new shortcut is giving the OP trouble in understanding what's going on.

I agree - the same thing happened to C++ to the point where it's almost unreadable now.

LOL. I think that's the primary reason why I don't do C++ anymore. That and someone has to pick up my code and maintain it after I'm gone and it's easier to find a C# dev (or Java dev we can convert) than it is to find a C++ dev for the team I'm on.

Is there a way to exclusively identify email-enabled public folders using Microsoft.Office.Interop.Outlook? EWS or PowerShell should not be used. The program should run on the workstation and utilize the installed Outlook.
Once I've found an email-enabled public folder, I should list the emails contained within it.
So far, I'm encountering difficulties. For instance, I have the following method:
static void ListPublicFolders(Outlook.Folder? folder, string indent)
{
if (folder != null)
{
foreach (object obj in folder.Folders)
{
if (obj is Outlook.Folder)
{
Outlook.Folder? subFolder = obj as Outlook.Folder;
if (subFolder != null && subFolder.DefaultItemType == Outlook.OlItemType.olMailItem)
{
Outlook.MAPIFolder? parentFolder = subFolder.Parent as Outlook.MAPIFolder;
string parentName = parentFolder != null ? parentFolder.Name : "Parent folder not found";
Console.WriteLine($"{indent}- {subFolder.Name}: {parentName}");
if (parentFolder != null)
{
Marshal.ReleaseComObject(parentFolder);
}
}
ListPublicFolders(subFolder, indent + " ");
if (subFolder != null)
{
Marshal.ReleaseComObject(subFolder);
}
}
}
}
}
The query
if (subFolder != null && subFolder.DefaultItemType == Outlook.OlItemType.olMailItem)
fails because subFolder.DefaultItemType returns the value Outlook.OlItemType.olPostItem, even though the public folder was set up as an email-enabled folder in Exchange.
Specifically, this is in Microsoft 365. In the Exchange admin center, when creating the folder, I explicitly checked the box for "Email-enabled." This action resulted in two additional options: "Delegation" and "Email properties." In "Email properties," I can specify an alias and a display name. By default, both fields are set to "Orders." Now, I expect the public folder to be email-enabled, with the email address orders@domain.tld.
I don't understand why Outlook is treating the folder incorrectly (I can only create posts and not send emails).
Perhaps someone can help me figure this out.
Thank you and best regards,
René

Hi All,
Stupid Question time. If a value is read to a textbox it is a String, to convert it to a value in the past I have done:
int Value = 0;
Value = Convert.ToInt16(textBox1.Text) I'm sure of it and then done maths and operations on the Value such as:
if(Value > 1000)
{
MessageBox.Show("Here!");
} But it won't run in VS2022 it returns a System.Format.Exception error. What have I done?

Don't use Convert as any error in the format of the input string will cause an exception.
Instead use int.Parse because you can check the result of the parse operation to see if you have entered a valid or invalid string.
From memory you should do the following
if (int.Parse(textBox1.Text, out int result))
{
}
else
{
}
|

You mean TryParse; Parse returns the parsed value or throws an exception.

What value is in the textbox? If it can't be parsed as a short using the current culture settings, then Convert.ToInt16 will throw an exception.
You should use TryParse[^] rather than the Convert method to avoid the "can't parse this" exception:
if (int.TryParse(textBox1.Text, out int value))
{
if (value > 1000)
{
MessageBox.Show("Here!");
}
}

Hmmm, I'm reading back a sensor, it's giving values all over the show!
private void button1_Click(object sender, EventArgs e)
{
if (int.TryParse(textBox1.Text, out int value))
{
if (value > 1000)
{
MessageBox.Show("Here!");
}
MessageBox.Show(value.ToString());
}
MessageBox.Show(value.ToString());
}
value is taken as 0, despite textBox1.Text having 1234.56...

But 1234.56 is a Float/Double not an Int; the two are quite different.

You are right, but even if make 1234 it still returns a 0...

Come on Glen, you need to show us the exact code, and the exact text that you are using.

Hi,
This is the code I have been trying to get all afternoon!
private void button1_Click(object sender, EventArgs e)
{
float ForceVal = 0;
<pre>
decimal.TryParse(weightTxt.Text, out decimal value);
if (value > 1000)
{
MessageBox.Show("Here!");
}
MessageBox.Show(value.ToString());
}
I think that should do it. I'm hacking together a test program that interfaces to a Phidget load cell in trying to measure a value that needs to converted to Newtons from Grams (I think!). I hate the fact I wasted so much time trying to get the value to be used out of a darned label. I haven't really done much Windows code (I'm an embedded guy really) since VS2008 was the new kid on the block and times like these it shows!

Did the TryParse call succeed, return true?

Sort of I had to:
decimal.TryParse(weightTxt.Text, out decimal value);
as I was messing with a floating point number, haven't coded in Windows for a while, man it shows!

Maybe try decimal.TryParse()? as the input is not an int.

I have tried to pass command line arguments to IrfanView to rotate a image, the code is below, the commented code works without a problem. The problem is the uncommented code, when the process is started, there are no errors but no changes are made to the image. I have tried the proper syntax code in VB.NET and it works as expected, any insight as to what's wrong?
//args = file1 + " " + "/rotate_r " + "/convert=" + file2 + "/killmesoftly";
//args = " " + file1 + " " + "/rotate_r " + "/jpgq=100" + "/convert=" + file2 + "/killmesoftly";
args = " " + file1 + " " + "/jpg_rotate=(3,1,0,1,0,0,0,0)" + "/killmesoftly";

I don't know why newbs always insist on breaking up what should be a single string into a bunch of string concatenations, making it harder to debug your code. You can do this all in one string:
args = $"{file1} /jpg_rotate=(3,1,0,1,0,0,0,0) /killmesoftly";
Take a closer look at your uncommented code:
args = " " + file1 + " " + "/jpg_rotate=(3,1,0,1,0,0,0,0)" + "/killmesoftly";
This will result in an arguments string that looks like this:
[file1]
Notice there is no space before the /killmosoftly switch. That will probably generate an error for the Irfan command.

Dave;
Thank you for responding, unfortunately the image was not rotated. As I stated previously the string works in Excel VBA & VB.NET with the correct file location syntax.
Thanks again for your help

I didn't say I knew anything about Irfan, only that your code is unnecessarily complicated, making it harder to debug.

Adding to Dave's wise words, your uncommented string doesn't specify an output file, so it may very well execute the process and discard the result.

Peter;
Thank you for responding. There is no switch for an output file, because the original file is overwritten.
