If this is in response to an article you should post it in the forum for that article, not here.

This is the third time you have asked this question. If you do not understand something about the explanations you have been given then go back to the original question and ask for clarification. Please do not keep posting the same question.

A heap is a memory storage and retrieval construct I learned about in college. It's a memory allocation and storage scheme not terribly unlike a stack. I honestly can't remember the exact details (from 1972...) but it's used extensively in compilers and other system level programming to manage limited memory efficiently. Google "memory heap", or consult Knuth's "The Art of Computer Programming" Volume 3 page 145. [Addison-Wesley, 1973]

Hey there!
I have a program that sends lines from a textbox which generally contains a lot of +, < and ~.
The problem I have is that the program does not always write out the tildes (~).
My code looks like this:
string T = this.TText.Text;
T = T.Replace("+", "{+}");
T = T.Replace("~", "{~} ");
statusLabel.Text = "Sending Text...";
progressbartimer.Start();
await Task.Delay(2000);
SendKeys.Send(T);
Is there a workaround to make it always write out the tilde signs so it does not just write it out as nothing?

Which program do you mean. If it is the one receiving the keystrokes then you need to explain what you mean by "not always write out".

My own program, a regular Windows Form.
Example:
I have a line like this in a textbox:
X: 24+/10~/<12
The program does not always write out the tilde, sending an output like this:
X: 24+/10 /<12

Sorry, but there is no way anyone can guess what your program is doing. You need to run it in your debugger to find out what is happening, and then come back here with some detail that we can work on.

I just tried it:
I added two textboxes to a form, and a button.
One textbox I called TText as in your example, the other I called OutText.
I then created a button Click handler:
private void button1_Click(object sender, EventArgs e)
{
string T = this.TText.Text;
T = T.Replace("+", "{+}");
T = T.Replace("~", "{~} ");
OutText.Focus();
SendKeys.Send(T);
}
I run it, and put your data in the TText box:
X: 24+/10~ /<12
When I press the button, my OutText contains:
X: 24+/10~ /<12
As I would expect.
So I have to assume that something in your code is filtering out the tilde before it gets to your display control.

Could it possibly be that I have a Swedish Keyboard and a swedish OS?
I always have to press space, or another button when doing the tilde sign. I'm not sure how it works for you.

Ah!
A quick google says it probably is: http://superuser.com/questions/414405/pressing-the-tilde-key-waits-for-a-second-key-stroke-how-do-i-disable-this[^] - Tilde is used for diacritics in Swedish systems.
Not sure how you get round this: I don't have Swedish Windows (and am not about to switch mine, I can't read the language except for the tiny bits I had to add for internationalization of some embedded software fifteen years ago).
This may sound like a silly question: why are you using SendKeys at all? There may be a better way that doesn't need the complexities.

I'm just going to drop a little something you might not know about SendKeys an d then step out.
SendKeys does NOT guarantee that the window that has the function when SendKeys starts executing is the window that gets the keystrokes. If another window pops up anywhere in the system, like a dialog box from a service monitor or another application, SendKeys will send your keystrokes to whatever window has the focus, including those other dialogs that are not part of your application!
Just a little food for thought. You may want to really think twice about using SendKeys.

Yeah, I'm aware of this, and I do not believe that is not what is causing the program to ignore the tilde.
I have been searching around on google, but cannot find any alternatives really.
What are good alternatives to SendKeys?
|
|
|
|
|
I never said it was the cause of your problem, only that there are pitfalls to using SendKeys.
The most direct method is to craft key messages and send them directly to the application that is supposed to receive them using SendMessage. You can find examples and discussion on the technique here[^].

I have a datagridview that items are being added to it. I have the code to check if the item has already been added. If the item has been added then I want to put that row into text boxes for editing.
Here is the code that locates the item that has already been added.
foreach (DataGridViewRow datarow in purchase_Order_ItemsDataGridView.Rows)
{
if (datarow.Cells[2].Value.ToString().Equals(part_NumberComboBox.Text))
{
datarow.Selected = true;
}
}
I have a form with text boxes to populate from the datagridview row for editing. I have tried this line of code to identify the row in order to get the data into the text boxes.
DataGridViewRow duprow = purchase_Order_ItemsDataGridView.CurrentCell.OwningRow; I end up with this unhandled exception ' Object reference not set to an instance of an object'.
I have been running in circles for a couple hours now and all I want to do is see if a duplicate is being added to datagridview and do something about it.
Thanks for the help
In the end I simply placed a messagebox after the datarow.Selected = true; and after the messagebox I used return; to exit the code block.

It should be easy enough to step through your code in the debugger to see which reference is not being set (duprow?). What are the values of CurrentCell and OwningRow in the above code?
|
|
|
|
|
As I stepped thru the code I realized that duprow is not being set. In fact I don't even need that line of code. The duplicate line in datagridview is identified with the line of code just before.
I can see now that I will be using a different method of locating a duplicate entry into datagrid view or use the datarow.Selected = true to process the notification to the user of a duplicate entry.

How to use dialog and divc tag in ASP.Net MVC 4
|
|
|
|
|
<dialog> is just an element you use in your views. There is nothing in MVC that prevents you from using it in your markup, but there is nothing that generates it either. You just wrap whatever code you want in a dialog element, then use a technology like jQueryUI-dialog to utilize it.
I've never heard of divc, and can find no reference to it.. so not sure what you're referring to.
