Data being erased

Question

My friend has a 30GB. He recently purchased an iPhone and since upgrading to iTunes 8 his iPod has erased itself twice. Both times it has happened within 30 minutes of being disconnected from the computer. He is running Vista.

Hi aeroFromSpace,
Thanks for posting in MSDN forum.
You need to debug your code and find out all the value of Rows, Value, count is correct.
Can you provide a simple sample to test this issue? I am trying to reproduce this problem. Actually, I have made a sample to test your code in a simplified version on my side. See this:
cliext::vector <int>^ data;
A fixed datagridview
private: System::Void MyForm_Load(System::Object^ sender, System::EventArgs^ e) {
this->dataGridView1->Rows->Add(2,2);
this->dataGridView1->Rows->Add(2,2);
this->dataGridView1->Rows->Add(3,3);
this->dataGridView1->Rows->Add(2,2);
data=gcnew cliext::vector<int>();
for (int i=0;i<5;i++)
data->push_back(2);
data->push_back(3);
Use your code to display the count to column3:
private: System::Void button1_Click(System::Object^ sender, System::EventArgs^ e) {
for( int index = 0; index < 4; index++) {
count=0;
int temp1=dataGridView1->RowCount;
cliext::vector<int>::iterator itt;
for(itt = data->begin(); itt < data->end(); ++itt) {
int temp=*itt;
if(temp == int::Parse(dataGridView1->Rows[index]->Cells[0]->Value->ToString())) {
count++;
dataGridView1->Rows[index]->Cells[2]->Value = count;
As above image, this works well on my side. If woulbe be better if you could make a sample for us to reproduce this issue.
