With the LoadLibrary function (followed by GetProcAddress) you can get a function or any other thing that is on DLL export. AFAIK, when you assemble one program, it loses all user-reading data (names in general). How do the OS's get them?
View 3 RepliesI am a newbie to C++ and VS ++. I have created a windows form application by dragging and dropping button, label..etc. i wish label text to be appeared as return value from a function. The function returns ' const char* '.how this returned string pointer can be used to display label text.?
View 9 Replies View RelatedI wrote this code behind a button
"
colordialog.showdialog();
File.WriteAllText("dlg.txt",this.BackColor.Name);
"
And I wrote this code in Form Load as well
"
this.BackColor = Color.FromName(File.ReadAllText("dlg.txt"));

but I got an error and I dont know what is this.... "Control does not support transparent background colors"
I'm writing a server/client application in C++, one linux and one windows. The generic communication method is to use the boost::serialization package, but I'll also use a header to distinguish the type of the serialized string.
Here is the struct that the two programs communicate with
struct SerializeString {
std::string type_name;
std::string serialized_string;
friend class boost::serialization::access;
template<typename Archive>
void serialize(Archive& ar, const unsigned version) {
ar & type_name & serialized_string;
}
};
When one side wants to pass an object to another side, it uses typeid(T).name() for the field type_name. The receiving side receives SerializeString and checks its type_name against various acceptable structs as follows:
if (ss.type_name == typeid(XXX).name()) {
// deserialize ss.serialized_string to XXX and do something with it
} else if (ss.type_name == typeid(YYY).name()) {
// deserialize ss.serialized_string to YYY and do something with it
} else if (ss.type_name == typeid(ZZZ).name()) {
// deserialize ss.serialized_string to ZZZ and do something with it
} else {
// etc...
}
This worked fine when I was using Windows VS2013 on two different windows platform. However when I switch one to Linux there is a problem because their typeid(XXX).name() returns different things. So question here, is there a generic way to get some sort of unique names across platform / compiler? Or is my method reasonable at all?
i have a vector of stores. i would like to delete the specified choice(store) from the list. Here is what i have but my erase statement is wrong and wont compile.
void Store::deleteSpecifiedStoreFromList(string choice) {
for (int i = 0; i < this->stores.size(); i++) {
if(this->stores[i].getStoreNames() == choice) {
this->stores.erase( std::remove_if( this->stores.begin(), this->stores.end(), choice ), this->stores.end() );
}
}
}
I am stuck on my program right now, what i am trying to do is get the sum of the amount from a access database table and than display it on a label, however i cant seem to get this to happen. This is what I have so far:
OleDbConnection conn = new OleDbConnection();
conn.ConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=Church.accdb";
conn.Open();
Form1 frm1 = new Form1();
//frm1.Show();
//string tableName = frm1.tableName;
//string time = "4/5/1991";
string fullName = memberscmb.Text;

I'm trying to print numbers in a label but I'm not having success. For example, I have the following code:
private: System::Void txtLeftWheel_Click_1(System::Object^ sender, System::EventArgs^ e)
{
for (int i = 1; i <= 1000; i++)
{
Sleep(100);
this->lblLeftWheel->Text = (Int32::Parse(this->lblLeftWheel->Text) + i).ToString();
}
}
The idea is that when I click the button, the numbers on the label increment from 1 to 1000.
The Sleep() is there to slow down the loop and the user can see something happening. However, if I put the Sleep() before the label->, the form freezes completely. If I put the Sleep() after the label-> text, the form freezes for a few seconds and the label text goes from 1 and jumps straight to 1000.
The expected functionality is that the label displays numbers 1 through 1000 but increment every second.
I have a label on my main form. When I menu select my settings form, I make a change to the label text on the main form but the label text does not update with the new text.
So here is my code in my settings form:
MainForm frm = new MainForm();
frm.paintMainFormThemeTitle(logoText); // updates the main form label
I may not fully understand the new instantiate key word, but doesn't this create another, new copy of my main form to operate on? And isn't that why I can't see my label text change on my main form that is previously in view?
All of the examples that I have been able to find show using this new key word to be able to access a component on another form. But to my understanding, I'm creating another, new form.
In my program I have WinForm and on this WinForm I have a User Control. On the User Control I have a TreeView.
So what I'm trying to do is passing a number, which is in the TreeNode Text to the WinForm. On the Winform I have a couple of Labels which I want to fill with Informations. To get those informations I have a class with a method which Needs my number from the User Controller. But I can not Access the Labels in the WinForm Method.
Here my code:
User Control
private void TreeView_SelectedNode(object sender, TreeViewEventArgs e) {
CwiaMain frmMain = new CwiaMain(TFS, TfsConnect);
TreeNode tn = _tvWorkItemList.SelectedNode;
if (tn == null) {
MessageBox.Show("Error");

My program has a goto label in it and when the program is not instructed to goto the label, it does. When control goes to the line that it is on, even if no where does it say to execute the label's content, it does execute it.

Value x is a 32-bit unsigned integer 3:
00000000000000000000000000000011
If we use bitwise-shift to shift all bits to the right by 2, x is 0:
00000000000000000000000000000000
If we then do a bitwise leftshift on x by 30, do we end up with:
11000000000000000000000000000000
or
00000000000000000000000000000000
In other words, when we perform right shift which clips away the least most significant bits, and then do a left shift, is it possible for those bits to reappear?
Here is a simplified version of my Menu class, where submenus can be inserted arbitrarily deep. I need to add a new functionality "go back to previous menu", which I would like to be activated by entering 0 (universal command for all Menu instances). I considered the Memento Pattern, but that doesn't seem to quite fit. add that functionality to my Menu class.

I am trying to use push back in a 2D vector but I don't know how to. This is what I have:
vector <vector <BigInt> > matr;
for (BigInt i=0;i<rij;i++) {
for (BigInt j=0;j<kolom-1;j++) {
matr.push_back().push_back((i+1)^(pow-j));
}
}
I quickly invented something but that doesn't work obviously. it should be equivalent to this: (the only problem in the code below is that those indexes don't exist yet that's why I need push_back())
for (BigInt i=0;i<rij;i++) {
for (BigInt j=0;j<kolom-1;j++) {
matr[int(i)][int(j)]=(i+1)^(pow-j);
}
}
