I have a richedit control which first time I am not able to clear out to nulls or have no value
Below is the code for CGRegs which a modeless Cdialog in which the client area is filled by a rich edit
as you can see all the way on the bottom I select the entire richedit and do a Clear
The first time around before General Purpose Registers Cdialog/richedit is filled I do a Stream out
I would assume the value of cb would be zero but its not its 0x7b for some unexplained reason more so
the value of the buffer of the rich edit is
pbBuff = 0x000001d45061df80 "{\\rtf1\\ansi\\deff0{\\fonttbl{\\f0\\fnil\\fcharset0 Courier New;}}\r\n\\viewkind4\\uc1\\pard\\lang1033\\f0\\fs17
Dont know what this is when I try to populate the the richedit with the register value it puts after the string
{\rtf1\ansi\deff0{\fonttbl{\f0\fnil\
\viewkind4 GPR 00=000000_00000114 GPR 04=00000000_FFFF
Any one the know who I can clear the inital value of the rich edit
thanks
static DWORD MyStreamOutGPRCallback(DWORD_PTR dwCookie, LPBYTE pbBuff, LONG cb, LONG* pcb)
BOOL CGPRegs::OnInitDialog()
{
gprrichedit = new CRichEditCtrl;
CDialog::OnInitDialog();
gprrichedit->SetSel(0, -1);
gprrichedit->Clear();
return TRUE;
}
CGPRegs::~CGPRegs()
{
}
void CGPRegs::DoDataExchange(CDataExchange* pDX)
{
CDialog::DoDataExchange(pDX);
DDX_Control(pDX, IDC_RICHEDIT22, (CWnd &)*gprrichedit);
}

gprrichedit->Clear();
You are creating a new RichEdit control so it will not contain any data, so no need to clear it. As to the other code you show above, I cannot understand what it is about; e.g:
pbBuff = 0x000001d45061df80 "{\\rtf1\\ansi\\deff0{\\fonttbl{\\f0\\fnil\\fcharset0 Courier New;}}\r\n\\viewkind4\\uc1\\pard\\lang1033\\f0\\fs17
is not valid, since the parameter is a long integer.

That’s the data I find the first time I call streamout with cb being x’7B’
Okay thanks

I think that is just the base control data for CRichEdit text, which is used to format it in the display. If you want pure text then you need to use CEdit.

Solve in C language:
1: "A savings account was opened with a deposit of $500.00. Imagine that this account is paid at 1% interest per month. What will the account value be after three months?"
2: "Make a program with 2 variables, A and B, where A will have the value 40 and B will have the value -1. Print the value of A+B, A-B, AxB and A/B. Then make B increment by a drive and repeat the 4 operations."

And what is your question?
|
|
|
|
|
as a starter, I give you the 'compute_interest' skeleton. To complete it is up to you
double compute_interest(double deposit, int months)
{
double interest;
return interest;
}

What does that mean? Is it a quirk of Google Translate?
Based on the language that I thought seemed reasonable given your CP username, I tried Google translate from English to Portuguese (Em seguida, faça o incremento B por uma unidade e repita as 4 operações) and back to English. That gives "Then increment B by one unit and repeat the 4 operations." - that makes more sense.

Maybe Google Translate tried to solve it and encountered a divide by zero error.

I think you are a bit harsh! We all had to learn! Maybe Codeproject should start a Beginners Page

Indeed we did, and for many of us there was no internet to help.
But there seems to be an attitude among a number of students (I assume a minority) these days that they do not have to put any actual effort into learning. We get regular questions in QA of this type, which at best are, "please do my assignment". Some of them even use the excuse that they don't have time to learn, or it must be ready by tomorrow at the latest.

The question is:
Do you seriously want to learn how to become an IT specialist, who can code, or are you more interested in the party type student life.
The problems you want resolved are quite trivial, and I could easily write you the required lines.
However, I will not! You seem to be early in your course. I have no doubt that your college provided you with the resources required where you can find out how to write this code. Read it, and Try it out, fail and Learn. Writing Code is about Trying and Learning, the whole time. You write the Code, Compile it. You get Compiling errors. That means that the Compiler does not understood what you wrote. Solve them, it Compiles. Now you have a running program or App. Does the App do what you want it to do! Very Often it does not. They call that Debugging!
I learned C and CPP/MFC the hard way. By myself, trial and error. My University simply did not have a computer that students could work with in 1974. My first computer was a Commodore 64 in 1985, where I learned the beginnings of Machine Code and ASM programming. A small PC with a C Compiler came as a godsend, and at the time I was in no doubt what compilers linkers, and debug/retail versions did and could do.
You have an institution with resources behind you. Use those resourses and learn. Stop asking this forum to resolve your exam questions.

Given following definition for singly linked list node and a pointer type:
struct Node {
int num;
Node* next;
Node() = delete;
Node(int num) : num{ num }, next{ nullptr } {}
};
typedef Node* NodePtr;
Use following prototype:
void quiz2(NodePtr& head1, NodePtr& target, NodePtr& head2)
to design a function that:
Takes in two linked lists, indicated by head1 and head2, and a NodePtr target
Searches target Node in linked list 1 (by comparing address, not by value):
If found, then connect the whole linked list 2 to the target node. In other words, use list 2 to replace nodes after target. Also update head2 to nullptr as the merged linked list should have only one entry point at head1.
If not found, then connect list 2 to the end of list 1, and set head2 to nullptr for the same above reason.
For example,
list 1: 10->20->30->40, target is the address of node 20, list 2: 11->12->13, then after calling the function, list 1 should be 10->20->11->12->13.
list 1: 10->20->30->40, target is an address that cannot be found in list 1, list 2: 11->12->13, then after calling the function, list 1 should be 10->20->30->40->11->12->13.
When merging, please take care of memory and do not let leak happen. You will be deducted by 10 points if memory leak happens. (Hint: in the first example, what should happen to nodes 30 and 40?)

Hi!
I am pretty new to this, but im trying to present when the latest winupdate was done on computer, and only found in powershell to present that, and i tried to run it in C#, but no error and no result.
I understand that im doing wrong, but what is the best way to do this?
private void LastWinUpd()
{
Runspace runspace = RunspaceFactory.CreateRunspace();
runspace.Open();
PowerShell ps = PowerShell.Create();
ps.Runspace = runspace;
ps.AddCommand("$a = (New - Object - com 'Microsoft.Update.AutoUpdate').Results");
ps.AddCommand("$a.LastInstallationSuccessDate | Get - Date - Format 'yyyy-MM-dd K'");
Collection<PSObject> results = ps.Invoke();
runspace.Close();
StringBuilder stringBuilder = new StringBuilder();
foreach (PSObject obj in results)
{
text_LastWinUpd.Text = obj.ToString();
}
}

What happens when you run the powershell commands in PowerShell and not via C#?
|
|

|

As the other Richard said, you've posted this in the wrong forum.
But you don't need to invoke Powershell in order to create and use a COM object. You can do that directly from C#:
Type t = Type.GetTypeFromProgID("Microsoft.Update.AutoUpdate");
dynamic a = Activator.CreateInstance(t);
DateTime lastSuccessfulUpdate = a.Results.LastInstallationSuccessDate;
text_LastWinUpd.Text = lastSuccessfulUpdate.ToString();

Hi!
Yeah if possible i want it in C# only.
I trid the code but i gives this:
0001-01-01 00:00:00 +00:00
|
|
|
|
|
What do you get when you run the Powershell code in Powershell on the same computer?

2021-09-20 is the result from PS command
|
|
|
|
|
The Powershell script and the C# code return the same result for me. Are you definitely running them both as the same user on the same computer?
